Phobos and deimos align every 10 days, so that seems like a good way to define a week to me. There are 687 days in a Martian year, and if we divide that into 13 full months and one partial month, we get 50 days in a month or 5 weeks in a month. The remaining time would be used to make a 35 day martian holiday period. We could either have this all in one go or spread it out by adding 2 days to the end of each month and a 7 day break at the end of the year that could be adjusted in length to keep the whole calendar aligned. That's my suggestion anyway.

3:43 A minor correction: The 23 hours and 57 minutes you give are the length of the sidereal day, meaning the rotation of the earth relative to the background of the stars. On the other hand, what we call a day, what we use for timekeeping and what you explained is the solar day: Since the earth revolves around the sun once a year, it has to rotate just a bit extra to make the sun appear in the same spot again - the solar day is is therefore a bit longer than the sidereal day (in fact the difference makes up a day per year, since the earth has to rotate once more to "compensate" the rotation around the sun). The solar day has an average length of pretty much exactly 24 hours, otherwise our solar noon would slowly drift each day. Otherwise a great video and thanks for your work!

I saw an idea for a Martian calendar that used 24 months and each month had 28 days except every 6th month had 27 days instead. The system uses 7 days a week like earth so each month is exactly 4 weeks (27 day months omit the last Saturday to keep things neat and structured). The system is also really nice because you can divide the year up into fourths which can make it easier to process since its so long. Leap years can also just turn the last 27 day month into a 28 day month which is very convenient too.

The base 60 system was likely created by the Sumerians giving that we have four fingers with 3 segments on them. Using your thumb to count the segments and using your other hand to keep track of how many times you did it you arive at 60. 12 segments on all 4 fingers, multiply that by 4 again from your other hand and you get 60.

For the purposes of intra-stellar colonization, wouldn't it just make more sense to use Earth years as the generic standard, with Martian years providing a secondary system predominantly used for crop growth and seasonal dictation? That is, of course, assuming that we are able to actually grow things on Mars outside of hydroponic systems with sufficient terraforming.

[@Yvaelle]

Mars time is completely useless. Nothing will grow on Mars surface for the foreseeable future (and I mean hundreds of years, we would need to reboot the magnetosphere - by reigniting the core of a planet - to hold a realistic atmosphere, before we could even begin seriously terraforming Mars). For hundreds of years, any humans on Mars will live completely underground to survive the surface radiation - no glass domes - just deep mines. All crops will be deep underground too. All lighting will be artificial, and will need to be on Earth circadian rhythms anyways. The purpose of measuring time is to coordinate with others - giving every rock a different system of time seems insane to me. We may as well give every person their own system of time: my minutes are different than your minutes.

[@frankb3347]

As I understand it 12 and 60 were used as in ancient Mesopotamia they had the idea that a perfect year would be exactly 360 days. Which is why there's 360 degrees in a circle. 12 and 60 are just handy units that divide into that evenly.

[@mageshwaridr.1927]

Note: *Minutes and seconds are in 60 not in 10 it's coz babylons who modified it and they always used to measure everything divisible by 6 and not 10*

[@markedwards9247]

Absolutely Dr Mageshwari. The fundamentals were sort of lost on this video. There is a fundemental difference between the calendar and the clock. The calendar is generally reciprocated by astronomical events of the particular planet you happen to be on. ie. One day is one rotation of the planet, one year is one orbit around the sun, one month is generally one orbit of the satellite, which is only really relevant for tidal reasons. The clock however, is not reciprocal with any astronomic events whatsoever. So it is within reason, and possibility to universally change the clock to a daily division of 10 hours, divided up into 100 minutes, and 100 seconds. On a different planet, all of those measurements would be different only because the 10 hours refers to one day. However, there would be little matter to say that a Mars day is 15 hours, 37 minutes, and 24 seconds long, whereupon it returns to 00.00.00. intrinsically, it doesn't matter, because any human living on Mars would find it difficult to adjust to normal sleeping patterns anyway. Biologically, we sleep when it is dark, and are awake when it is light, over a 24 hour period. The Martian day would mess that up completely.

The weird stuff comes in how school years get broken up. With years on Mars being *almost* 2 years on earth (687 earth days) a person would either be considered an adult at 9 or 10 Martian years (17.8 or 19.7 Earth years old) and standard education would start at 3 or 4 Martian years old (just under 6 or just under 8 Earth years) meaning there would be between 5 and 7 Martian years of basic education.

The reason they used 12 and 60 is that if you look at a finger on your hand your finger is divided into 3 parts, so if you count them up your 4 fingers by 3 parts of a finger (you don't count your thumb) then that counts up to 12. So when you reach 12 on your right hand then you raise one finger or thumb and that counts as 12, then you continue counting until you reach 24 and then you raise a second and so on until you reach your 4th Finger and your Thumb which is 5 x 12 which gives you 60. Hence the 12s, 24s, 60s etc. This counting system of time is over 5,000 years old and originated with the Sumerians and is the reason the days and years are divided into 12 hours or months.

Just wanted to come down here and say that the "60" is a hold over from Sumerian/Babylonian system for tracking time. They used a base-60 system, in which you count each knuckle on each finger that isn't your thumb, and then use the fingers on your other hand to count up 5 times. 3 knucklesx4 fingers=12 (where we get the 12 from in time). Then 12x5 fingers on the other hand make 60.

solar day is the time between two succesive moments of the sun being at its maximum elevation. The sideral day is the same thing but with a very distant star.

The sexagesimal (base-60) system was developed by the Sumerians and is an extension of the duodecimal (base-12) system, which is convenient for counting on one hand - each finger has 3 bones, so the four fingers make 12. Every time 12 is reached, one finger of the other hand is held down, so the 4 fingers and thumb of the other hand make 60.

[@TheBluverde]

In Kim Stanley Robinson's _Mars trilogy_ settlers use regular terrestrial watches that stop ticking at midnight for 39 minutes and 40 seconds before resuming their timekeeping.

[@llearch]

"Comp" time is not an unusual thing in Science Fiction; a set of minutes at around midnight that resync the hour to the local physical planetary hour for the new day. Connecting this to UTC is... unmentioned, but it's generally accepted that cross-system communication is laggy at best, because that makes for better storytelling, but also means problems like this can be hand-waved away. Mind you, it also bears mentioning that we won't be able to use the internet to talk to Mars, because TCP has a timeout in it that is shorter than the lightspeed travel to Mars, and hence you won't be able to send data between the two planets fast enough to keep an internet link up; you'd have to encapsulate it in a different protocol, or run a gateway of some sort. So some of the timesync issues are less important on a tiny scale, provided each planet keeps itself sorted, the wider universe is just fine.

For example, US english vs UK english vs NZ english all have slightly different ways of referring to the same time, and I can never remember which is which...

[@quantumsoul3495]

We should take an universal approach. 1. Small periods need to be understood by everyone, minutes and hours need to be universal: - 1s defined by SI - 1min = 60s - 1h = 60min 2. For common history we need an interplanetary date system, alternative to the current day-month-year. Since month is mainly useful for seasons, a two part system is more appropriate. Let's call them Rev and Rot. - 1 Rev = Average year length of solar system planets, in seconds - 1 Rot = Average day length of solar systems planets, in seconds Date would be written th . For example: "Quantum supremacy was achieved on 162th 24". 3. For planet-wise history each planet would have its own "year-month-day-hour"-like time. Year tells revolution Month tells seasons Day tells rotation Part tells parts of day (1 Earth Part = 1 hour)

[@TimeMeddler]

A few things not quite right here. First, although months on Earth have their origins in the lunar cycle, they have long since become separate and are just generally the year divided into 12 units. This originated millennia ago, in particular with the Julian calendar and the Egyptian one that it was based on. Second, the Earth day is not a fixed length, it varies according to the time of year and other factors. However, we use the 24-hour day as the MEAN day length. The 23 hours 57 minutes relates to the time it takes the Earth to rotate 360 degrees, which is not a full day in human terms. It takes a little longer to rotate to our day, i.e. from midnight to midnight, because the Earth has by then moved a little farther round its orbit and the sun has moved apparently a little further eastwards in the sky. And lastly, it’s spelt “Martian”, not “Martion”.

Actually, Mars is currently not the most habitable of bodies in the solar system (if you include moons) That title goes to Titan. Sure, youd need a heated suit in order to not turn into a popsicle on Titans -180°C surface, but the same is true for Mars. Furthermore, you dont need protection from the sun, or, for that matter, radiation, as Titans thick atmosphere, Saturns magnetic field, and the distance from the sun for the two of them will do that for you. Youd also need a modified oxygen mask to breathe on Titan (Its atmosphere is some 95% Nitrogen and 5% Methane at a density of 1.45 atmospheres, but as long as you adjust your masks pressure output accordingly, thats well within pressures that humans can breathe in) but the fact you dont need a full on space suit to walk around on Titan makes it way more habitable than any other body in the solar system, besides the earth itself of course.

And each dozen was counted on the other hand, 12x5=60. When they counted minute(small) numbers they divided it by 60, and when they divided those minute numbers a second time, they called it seconds.
