House Division Calculations in Astrology Explained

[@TheAstrologyPodcast]

Let us know what system or systems of house division you use below! Also let us know if you have any questions!

[@mesmer1218]

Whole Sign Houses and sometimes Koch.

[@spiritofmatter1881]

Grew on Placidus because astrodienst. Tried whole sign after watching your houses, signs planets cast with Kelly and Austin and I like it a lot. I am biased as I like the story my chart tells in whole sign which is even funnier than Placidus. All in all each system adds its own perspective. I cannot say one is more accurate. Now I am studying Uranian which has no houses and signs at all so that's a shift in thinking as well. Very interesting topic! Thanks for sharing so much technical details/topics on the cast. It is good food for the astro geeks.

[@Invictus7941]

Whole Sign House and Placidus, Regiomontanus for Horary, and a consideration of all for every read, purpose and need. If only we had the charts of exact time of each house system..

[@shaktiveda7041]

Hey there, good to see you doing well! By the way, although it would be in some ways a little boring, I agree with you there, I have to admit that there is a part of me that has been very curious to see how that clock actually works from the inside...Since childhood I always like to open things up to find out how they're actually made, done or work, so yay, an explanation on how to draw our own chart from scratch would be very good and helpful even though I am not exceptionally incline to math I still can take simple stuff as long as we're not diving into trigonometry, thank you for your care and for share Chriss! Ps: You are both right about this, in my opinion too I think it is important to know how to pull our own chart even without the computer and even if we might end up not using it too often, at least there will be some bare basic there to help us lay better foundations.

[@miamedina1419]

Whole sign and placidus

[@VicDiCaraAstrology]

This is QUALITY.

[@murilkaa]

I would absolutely love the episode about calculating charts by hand! I've learned how to calculate a few things in order to understand them better, like the lots and harmonics (I was going through a phase), which of course are pretty simple to calculate, but it was very useful to train doing maths in terms of degrees. So yeah, learning how to do the whole chart would be pretty awesome!

[@CatBearChick]

yes!

[@Stoic_Astrology]

Muriel are you on Instagram?

[@LouValcourt]

My condolences on your loss Luis. Thank you to both you and Chris for a highly informative episode.

[@shadesofbrooklynn5]

‘On the heavenly spheres’ was my first astrology study-book. It is Amazing, so understandable and clearly written. ThankYou for passing on thhe Knowledge Mr Ribeiro and Mrs Avelar 🙏

[@M313-u8d]

Apparently you should also get their companion book for reading On the Heavenly Spheres, do you think one can only do with the latter book alone?

[@shadesofbrooklynn5]

@@M313-u8d hello, I did not get the companion book. It takes some time to absorb the info, maybe u could order just the first book and work with it… if u notice that u might not grasp the concepts well u always can order the companion book. It depends on how deep you wanna go with it…

[@sonyak9879]

Yesssss please a session on how to calculate charts BY HAND💖Please and thank you so very much...... P.s. I could listen to ur guest speak for hours🌹 That voice☺

[@empressadelexxmotherofjohn10]

Voices are incredibly personal and individual. 😀♌⛎🔯🔱

[@katiemarie144]

I would love an episode or a few on calculating charts by hand!

[@csabasaf]

I love this video. Finally the illustrations helped me to get the difference between the house systems. In most books, the differences are poorly explained and there are rarely figures showing what exactly happens in the sky. No wonder a mathematical dummy like me didn't get it.

[@kCeciliaNightRain]

Wow! This has got to be one of my all time favorite episodes. It was super fascinating being able to visualize the way houses were divided. And awesome to insert historical information as always. Those image animations were super helpful; great presentation… will definitely be rewatching again :) ✨

[@Akaridances]

I went to school in 1978-80. We learned but i since cant remember. I think the great part for people is that you can check the math with the computer.

[@daniellebrook3333]

I wonder how many hours of my life have sat in front of my TV watching your podcasts??? What's a few more? Of course I would love a series on writing a chart!! I really appreciate all your podcasts Chris, I've learned so much over these last couple of years. I'm never board. Thanks again 😎🤩

[@quietwyatt4045]

This should go in the “Greatest Hits” of the podcast. This topic is never covered with the necessary technical attention it requires. That’s understandable to a degree considering all that is involved. Nevertheless, it’s really fantastic that you _did_ take the time required to give this the attention it deserves.

[@01Esoteric]

I am a new student of the course on chart rectification and I'm going through the basics here before I proceed to part 3, and YES, I'd love a video on how to calculate the chart by hand, if you haven't done it yet.

[@miabernau7908]

Whole sign houses works very good . Thanks the two of you very intresting good work ❤️❤️

[@HauntedCerebralAstrology]

This was an epic meeting of two great voices in astrology, fantastic! Would love to see you both together again in future podcast episodes! Thank you! x

[@brittanymcnair8238]

I’d like a chart calculation episode. And thank you so much for for your work, I’ve learned so much. Got your book.

[@kippbleu8289]

This is a video all astrologers need to watch before choosing ones preferred house division. Great stuff! 🤓👍

[@khansenvt]

I would love an episode on calculating charts by hand! I love this channel so much. Thank you, Chris.

[@rebellerevelle]

Wow, thank you both for a generous, comprehensive overview of the house systems. I don't know how you can go on for 4 hours without taking a break! I greatly appreciate the helpful visuals to explain the differences between the systems. My sincerest condolences to Luis, and I look forward to learning more about his and his late partner's work in your other videos! 🙏

[@sarahkris7011]

This is the BEST thing I've ever seen. There are no words. THANK YOU!

[@stephaniejakobs8273]

Yes! I have forgotten how to calculate charts and personally understand more when having to go through the steps manually.

[@eternalcheesecake]

I've been waiting for years for this kind of explanation of the house systems, this has brought so much clarity to my mind, thank you!

[@treesa2732]

Vedic Astrology podcasts Fiona Marques is a double mathematics major and her natural wonder and ability to think and communicate the language of Vedic Astrology, through her lens, is fascinating and i feel a great contribution to this field ! She is also in Portugal.

[@nathaliescutari1407]

I would love an episode about how to calculate a chart by hand.

[@devanirguna]

For me this was a very informative episode by setting the houses in their mathematical and historic settings as different attempts to give structural meaning to our view of the heavens. Maybe now we can take the next step of giving each of them their distinctive interpretative value so maybe we can move between them for different consults. For the first 40 ears i just differred to Koch without much real enthusiasm now I enjoy the simple solidity and elegance of whole sign houses but now feel open to the possible nuances of each system

[@solmma]

I didn't know how important this information is!! Thank you so much you two!

[@shelliecrowastrology2923]

I use Porphyry because my teacher recommended it, but I am not particularly attached. I would love to learn more about calculating charts by hand. That seems to be a most valuable skill for an astrologer! Thank you so much for this episode and all of your amazing episodes. I learn so much from this podcast!

[@aqualeo-leo3063]

Eyes Wide Open. Thank you Luis and Chris. I had been using the Koch House System since 1985, when I picked up The Koch Book Of Tables, and learned how to cast a natal horoscope. After this podcast, I will experiment with other house systems, (e.g., Whole Sign, Alcabitius, etc). I enjoyed this podcast very much. Thanks, again.

[@geminibrett]

2:10:15 I like "angle of Earth" for the I.C. as well. First time I've heard that. I call the IC "the Root". The four Rs describe the astronomical happenings at the pivots (the angles)... The Rise (AS), the Reach (MC), the Rest (DS), the Root (IC)

[@mari2710br]

I was thinking about that...and then you post a class about it. Fantastic! 👌

[@isshaelaingham9396]

yes please! The way the Astrology Podcast would present house calculations would be an amazing opportunity and learning experience

[@alfialambert5777]

Thank you so much for this episode, Chris and Luis! Amazing visuals and even more amazing content. I did not notice how the time flew by.

[@kstar313]

I really enjoyed this discussion. Thank you so much! Really clear descriptions and beautifully illustrated with visuals and examples. You both have such pleasant, soothing voices and communication styles 🌟 chart calculation demonstration would not be too boring for me 🤩

[@geoffgrigg]

This is so interesting. The technical interviews are really valued. It would be amazing to see a video of how to calculate a chart. Thanks for another incredible episode. I do whole sign houses. This edition has prompted me to try others.

[@Holybasil29]

Thank you, for this and the other podcasts. love them all. Yes, please have a talk/Demo on manually calculating the Natal chart.

[@17Radiance]

Providing the world does not blow up, your book on Hellenistic Astrology, I am sure, will be read centuries from now! :) Fantastic episode with Luis Ribeiro!

[@mari2710br]

29:43 Yes, exactly! people don't use the whole sign house system for its simplicity, we use because it works better, it is more clear and coherent... even when we are aware of others systems we stick with this system! the choice is simple not the system :D

[@SaraFaithJacobsen]

i just switched to whole sign from placidus, and i love whole signs!

[@YouNolf]

But what about planets that have risen over the horizon still considered as first house? Or planets under the horizon that have set, invisible, and still considered in the 7th?

[@ginadiamond2959]

Interesting point you made about learning how to cast a chart by hand...I am in the Level-1 Course for certification with the NCGR and the one thing that I am most excited to learn is how to calculate a chart by hand. Doing things by hand or writing really impacts my ability to full comprehend what I'm doing and in turn with add more depth and meaning in reading these charts. This video is A-1. I am leaning in on the whole house division because I love going back as far as possible in time but for the sake of my certification and for keeping in modern times, I will study both Placidus and Whole House. Bless you and your work and all of those you collaborate with to so generously give these lectures.

[@karen.hunter]

Brilliant lesson, thank you both ao much. It will take me a few repeat watches to really appreciate the second half. I was very sad to hear about the passing of Luis partner towards the end of the video and will watch the follow up session to find out more about her and her work. Blessed be.

[@geminibrett]

I'm so stoked to watch this. Thank you! I'm writing early in the broadcast to say, yes, I think it would be wonderful and important for you to have a show on how to hand draw a chart from tables, Chris.

[@stevenvallee1369]

Yea i want that boring podcast about how to calculate charts by hand, in any form it takes!

[@ewadsworth]

Agreed. I'll second that vote! And it would not be boring, I'm sure we'll all be hanging on the edge of our seats🤤🤣🤓📚📝💰🙏🏾

[@mabsweb]

Agreed!

[@mathhew7352]

Yes!!!!!!!!!!!!

[@growing.grounds4054]

Yea the astrology podcast trolling now 😂😂

[@jackque5199]

So glad I found this. I am just starting my journey with astrology. I reread the first part of my book thinking I missed something reading about houses. I didn’t miss it because the information wasn’t there. It is very confusing being new to have one system say my moon was in 3 various houses depending on the house system. I could understand what was being explained in this video. I thank you very much. I did have to watch it at 3 different time intervals to allow myself to absorb the new to me information.

[@geminibrett]

3:38:00 This is a wonderful point you make, Chris, regarding modern astrologers basing the application of different house systems upon the sources of those systems in practice. The example you give is that some modern astrologers claim Whole Sign is more applicable for prediction and Placidus more applicable for psychological investigation, which might be based, not upon what those house systems do, but rather upon astrologers who use them. Modern astrologers see many modern psychologically-inclined astrologers using Placidus and learn about the use of Whole Sign houses in the Hellenistic period when astrologers were more predictive. I use several house systems, but source their applications astronomically (or rather upon my own projections of what their astronomical basis might suggest). In that approach, I suggest quadrant house systems are actually more Earthly than other systems since they are entirely dependent upon a very specific Earthly experience of the Heavens. Of course, Whole Sign house are based upon an Earthly experience of the astronomy as well since the first sign is determined by the Ascendant, but in any given movement of time, that rising sign is rising for about one twelfth of the Earth. We need both AS and MC degrees to determine a unique location for any moment of time.

Chris I think learning the chart by hand would be very useful, it is very important to know the details of the discipline you are working on. Thank you for thinking of it.

[@libragem]

This is why as a math professor I was always against calculators while learning the foundations (theories).

[@e.chandrikagalbacs2449]

Yes, please do a podcast in the future about calculating house divisions. It’s like trying to do math word problems without knowing any very basic arithmetic. I believe it would reinforce a basic foundation for astrology.

[@SimiliaSC]

I feel that the Calculation of a chart by hand is one of the most crucial parts in learning astrology. For it will make very understandable why a chart looks like that at any given time. Please do such a podcast as it will benefit the whole astrological Mind Group...

[@tychase7491]

Chris, I remember when you had Benjamin Dykes on the show to talk about his latest translation interpretation work on Abu Mash'ar solar revolutions and time lord techniques. The two of you discussed the issues that Abu Mash'ar was experiencing with whole signs and divisions deciding which system worked the best when a problem arose regarding a specific technique. Benjamin dykes teased at a possible solution for said issue regarding house systems and the potential for a new approach to apply a hybrid system or a combination of both at different times. Whether it would be ethical or even work, or even if we should be, it would be a great discussion with many tangents.

[@holypunk12]

Very nice explanation !

[@louisetrimble3490]

I think astrologers should be capable of doing charts by hand. What if the grid goes down?

[@omentum1000]

I tend towards whole and Koch house systems and would love to see you do a series on hand calculation.

[@smriti987]

FREAKING BRILLIANT!!

[@gracie_5]

Because of astronomy i use vedic astrology only. But also there are over 5 house systems giving different houses in planets. So in the end i say, look what stays stable and in aspect and what houses move flexible. Then use a range of characterics in these life areas. Beside, charts in pregnancy exist too and human design and numerology added gives a whole set of insight. Only problem is the hobby community like being stagnant on one house or stellium, but degrees were so fine between two houses, that they change

[@anm2945]

It's more than arithmetic. Mathematics has a process. It's useful for everything. Thanks. Great programming.

[@mesmer1218]

I would love a podcast on calculating charts. There’s no telling how the world might shake out and I think it is important for us not to let this valuable craft vanish into the abyss of forgotten wisdom, especially since so many good souls have worked so hard to restore ancient techniques and history. Luis is awesome and I love his devotion. Thank you for the interview. I will definitely follow his work!

[@user-sc8ek9qj5o]

Yes please do it, would be very interesting to learn

[@pamelajoy6037]

Thank-you for this. It is valuable information. I use Placidus by default, via Astrodienst. However I am fascinated by the different House systems as they were explained by the late Howard Sasportas in his book on the Houses. My first class many, many years ago was to calculate the chart by hand. For convenience sake I appreciate the computer service saving. me the time. However, becoming involved in hand calculation deepens connection to the meaning and feeling of the astrology.

[@JWM80]

Thanks for a thorough and enlightening discussion. For the longest time I avoided looking into the origins of different House systems because they all seemd so complex and overwhelming. My current preference is for time-based systems - given that the Houses are based on Earth's 24-hour rotation. I still prefer Placidus for natal chart readings because it appears to be more accurate in interpretations, as well as Topocentric for transits. But I'm somewhat intrigued by the simplicity of Whole Sign and Equal House systems, even though I find them less accurate when interpreting charts.

[@geminibrett]

1:23:58... regarding the numbering of the house, which might seem backwards since the Sun (and all Planets and Signs and ecliptic stars) rise from the quadrant 1st House into the quadrant 12th... the 1st House is the first to rise, the 2nd rises second (after the 1st), etc. The first is angular because it is applying to the angle of the Ascendant, the 2nd is succedent because it succeeds the 1st to the Ascendant. The 12th is Cadent (which means falling) because it is 'falling' away from the Ascendant. The Falling nature of the cadent houses is easier to see with the 9th and with the 6th. The stars of the 9th (cadent) are falling away from the MC while the stars of the 10th (angular) are applying to the Mc. The stars of the 11th (succedent) will then succeed the stars of the 10th to the Mc.

[@sarahsierz233]

Yes I want to learn how to calculate charts!!

[@Mr0rafael]

Awsome, as always. I use placidus, but I just got into tradicional astrology, so maybe I'm going to use whole signs... But I'm pretty confused since I'm new astrologer...

[@astraeusgodofthestars676]

I haven't finished the podcast yet but please do a podcast on how to make a birth chart manually sir Chris. I'm your fan from Philippines ✨

[@vintagenewsaz]

Please could you do an episode on the math? May I suggest to keep it watchable, short and to the point with visuals. I’ve been studying this right now and I am desperate to watch a good visually engaging way to learn this. It doesn’t seem like it should be hard at all but for me, keeping my attention on it is so hard. I open my Math of Astrology by Murphy and Rosato and then I get interested in another aspect of astrology and I’m down the rabbit hole! I have not had an actual lecture on the subject and it would really be great!

[@CosmicIntelligenceAgency]

Thanks for this! Wonderful work to explain this all in such a graphic and real time way! After all this i think I'll go back to Placidus! Chart drawing is essential, and one learns a lot, but now we have this! add ing learning the use of the astrolabe would also fair well to be added. Have always wanted to animate an ASTROLABE type chart - like in the Scheme of Heaven by Alexander Boxer.- he mentions in this book Valens using an astrolabe device.

[@geminibrett]

27:00 so probably premature as this might come up during the astronomy section, but I will voice now that only the Equal House System shows the highest altitude degree of the ecliptic above the horizon, which is always 90 degrees from the Ascendant (Equal 10th Cusp). Many astrologers incorrectly teach that the Meridian MidHeaven (Mc) is the highest point of the chart. It is not. The high point is the nonagesimal, the cusp of the Equal 10th, which is always in the 10th Whole Sign.

[@rosyb16]

True. Based on what I've seen, this seems to have a lot to do with the fact that many of them also teach that the Midheaven (MC) is the cusp of the 10H because some house systems tied that angle to such house. However, despite the MC being commonly described as the highest point in the skies from the specific location where a horoscope is cast, this point is actually the intersection between the Meridian and the Ecliptic where that particular degree is in its minimum distance to the zenith during its path throughout the day. The MC can't be properly described by direction (north or south) because this definition does not work for tropical, equatorial zones (for a horoscope cast for a location already in the Northern Hemisphere but very close to the Equator, the MC will be North to their already Northern location blurring the cut and dry concept of such direction. The MC can't be properly described by its position above the horizon either (above or below) because this definition does not work well in the polar zones (during the summer, we have the midnight sun with this celestial body spending 24 hours above the horizon because it does not rise or set in relation to the horizon). Because of these differences regarding the location used to cast a chart, when the MC is projected onto the houses, this angle does not necessarily fall in the 10H, and these two are not the same thing astronomically speaking.

[@Luis-Ribeiro]

True, the nonagesimal is the exact 90º from the ascendant degree, thus the highest. However the point of the quadrant system it is not to do with which degree is highest from the horizon at the time of the event, but to which zodiacal degree (= quality) is culminating, thus reaching it's highest point, at the same time of the ascendant degree - the point representing the essence of the individual/event/question corresponding to that time, date and place. Thus at the same time an ascendant degree rises (=is born) another specific degree its reaching its highest peek possible. Otherwise (except for 0° Aries or Libra) in charts the nonagesimal degree has already culminated or will culminate in the future.

[@geminibrett]

@@Luis-Ribeiro and, therefore, the meridian MidHeaven better qualifies as a "pivot," right? The Mc is where celestial bodies pivot from climbing up to going down. I like to call it the Reach (Rise, Reach, Rest, Root for the four angles). I also call the Mc the high point in time whereas I call the nonagesimal the high point in space. I usually cast Porphyry charts because they help me see the sky in the chart and the pivots, but I also work with a whole sign approach and I keep my eye on the nonagesimal degrees as well. I've had success working with both Mc and upper nonagesimal degrees for vocation signatures, for example. A final argument for the astronomical power of the nonagesimal (and maybe for Equal House, which I don't personally use) is that the nonagesimal better fits the name "MidHeaven" as it is the middle point between the Ascendant and Descendant and is the highest point of the ecliptic. I was born with 10 Gemini rising (azimuth of 60) and 14 Aquarius Mc so my meridian Mc isn't close to the high point or the midpoint between AS and DS. I like that, just as my AS is 30deg north of East, my nonagesimal above is 30deg east of South. I consider Equal Houses to be an expression of a natives "personal directions" whereas the meridian (and therefore quadrant charts) tie the native to "Earth's directions". I will say that I work very little with Porphyry cusps other than the Angles. I haven't tested them, but something in me doesn't get trust quadrant cusps. This wonderful discussion / presentation has convinced me to look into Alcabitius Houses. I would like to start working with house cusps more.

[@Luis-Ribeiro]

@@geminibrett "better" as pivot is perhaps a too definite since its efficiency (as you point out) must derived from experimentation and confirmed with results. :-) In the podcast I completely avoided the discussion of "which one works better" because that was not the objective. My point in my reply to you was to note that there seems to be a correlation (like the one in parans) between the ascending degree and the one culminating at the meridian. As to the Midheaven being better described by the nonagesimal, I disagree. The nonagesimal marks the middle of the ecliptic arc above the horizon and it can be argued that a greater circle can pass by it and divide the sphere in two equal parts. However this division would move constantly throughout the day making it difficult to be discerned by observation. The meridian on the other hand is a fixed arc. It "cuts" the natural and visible movement of the heavens in two and long before there were house systems it was as you know used (for these very reasons) for time keeping. So I believe that the natural ability to observe the meridian point and therefore the culmination of a given celestial body trough it gave it the power it has. Now in my opinion and from my reading of this matter (historical and otherwise) the nonagesimal works as long as you have a more "symbolic" astrological chart and looks nice on paper. But once you begin considering motion things get more complex because the nonagesimal will not be (in almost all cases) the middle point of this movement. This probably is one of the main reasons for the shift to quadrant houses. But we could be discussing this for an eternity :)

[@geminibrett]

@@Luis-Ribeiro Oh, I mean just astronomically. "Cadent," for example is a much better fit for a quadrant ninth house which is actually falling vs. a whole sign ninth which might still be climbing. I couldn't agree with you more the only experience will give me confidence with cusps. I have success with the whole sign houses so it's going to take some discipline on my side to go there.

[@Invictus7941]

Just as I was working through Hellenistic Whole Sign House vs. Placidus vs. Regiomontanus (esp for Horary) the consideration of all, how it differs based on purpose etc. I think that they are essentially all different perceptions of a whole. The circle of 360 degrees as a cyclical union with no beginning nor end, it is us who coexist as part of the universal map, both part of the circle and cycles, while also the circle as a a line, and path that we walk on. Time versus eternity, the physical hand in hand with the non-physical, all these systems have their place and purpose.

[@halfpence1359]

I kinda use my own house system which is the ‘midnight to midnight’ system. To describe the system I use the lowest point of the sun in the sky to calculate the ascendant, I’d use an app called night sky to calculate it and then use that point to calculate the dominant sign and the karmic sign which are east and west respectively, before using the descending sign which is the highest point the sun is in the sky. Then I use the equal house system atop of it but I make it clockwise to follow the suns path rather than the anti-clockwise house system.
