[@CraigKostelecky]

A few years ago, I decided to try to make my own calendar and let the seasons decide the month length and I was amazed at how well it works. First you start your year on March 1 and sync that up with the spring (I'll use the northern hemisphere for all of my seasonal names) equinox. Spring is 93 days long, so March, April and May all get 31 days. Which makes June 1 the start of summer. Summer is also 93 days, so June, July, and August also get 31 days. So September (which is now the 7th month again) begins on the first day of fall. Since autumn is 90 days, each month gets 30 days. And that leaves us with winter beginning on December 1, which is 89 days. So December and January get 30 days and February gets 29 or 30 days depending on leap year. With this calendar, you always know which season it is based on the month you're in and it's super easy (barely an inconvenience) to know how many days are in each month. There is no completely arbitrary date which the year begins. And finally the names that use numerical prefixes again make sense. The only downside is transitioning to this calendar would be difficult as we would need to shift the dates back by about 20 days (or ahead by about 345). Edit: I later learned that this calendar is the same idea as the old Persian calendar.

[@aaravdiwakaristhebest]

I appreciate ya

[@AJAYSINGH-ns1vv]

Because you got very near to hindi calender which is oldest and most accurate.

[@JohnFallot]

Intriguing! I’m tinkering with a calendar myself, although my approach is to just add a 13th month and make all the months 28 days long. There’s also an Intercalary period for New Years, which is 2 days long on Leap Years. Aligning that with the seasons (starting from the winter solstice) means Spring always starts on the first week of the 4th month, Summer on the 2nd week of the 7th month, and Fall on the 3rd week of the 10th month.

[@MrsKoldun]

Would have been great to explain why 01.01 was chosen as the start of a New Year. In Ancient Rome 01.03 was the start of a new year (marking September the 7th month just as its name suggests, and so on for October, November, December), thus making January and February the last two months of a year. However new officials like consuls assumed their offices on the 01.01 and over time the calendar was matched with this date, taking the last two months and pushing them to the front, consequently causing the names of the months to be out of sync with their position in the calendar.

[@tompoessy]

no, the reason theyre out of sync is because january and february were added later, it was originally a 10 month calendar, with the months martius (march), aprilis (april), maius (may), junius (june), quintilis (july), sextilis (august), september, october, november, and december

[@seanvasquez523]

@@ChoCoMoCo69, Yeah and when you think about it I think most ancient calendars and some modern calendars that don't use the decimal system in them didn't even have a year zero in their systems to begin with because they don't know such number ever existed or even if they did have a idea of what it is was, they either didn't have a symbol of it didn't knew all the general concept of it well enough and couldn't use it so some numeral systems didn't have a zero in it. So I think the Indian calendars and other modern calendars are exception to this because not only the Indians "invented" the zero but we also now have a general idea of the decimal system and the number zero because of Hindu-Arabic numerals. That's why no one gave a big deal about no year zero in our most used calendar system anno domini until around the time when the Gregorian calendar came to be a thing, when both Hindu-Arabic numerals starting to be used widely, and both the concept of zero and the decimal system came widely in Europe around the time of the calendars introduction so that's why after the calendar introduction Astronomical year numbering and much later ISO 8601 were made in the first place so to get around this problem.

Y2K was a real worry. Not in terms of end of the world (obviously), but in terms of badly designed computer systems not coping with overflow from 99 (1999) to 00 (2000).

Today is the 16th day of the ninth month of the year 2076 according to Bikram Sambat, the official calendar we Nepalese follow. Months can be as long as 28 days to 32 days. We also go by a different calendar(which follows lunar days/tithi) that is mainly used for religious purposes, as in determining festival dates, auspicious date and time for weddings, coming-of-age ceremonies and so on. Astrological signs also differ from (what is considered)the usual as the 12 zodiac signs are assigned according to the 27 nakshatras(don't know what to call the English equivalent of it) you're born under.

The Indian calendar seems to have a good amount of similarities with the Chinese and Hebrew calendars. But then again there apparently are more than one traditional calendar systems that's followed in India.

[@user-uq1wq2mz2q]

Westerners only look at the sun, and Arabs only look at the moon. The Chinese calendar is based on the sun and moon.

@@booksanimeenthusiast3802 but, the Indian calendar does not start every month with a new moon, nor does it mean that every month 15 is a full moon.

What I certainly know about the Ethiopian calendar is that it is just the Coptic calendar with different names. The name change happened when the Ethiopian church split from the coptic church, the coptic calendar was made to determine the months of farming and harvesting, and it is still used in Egypt to this day but rarely. Idk about whether Ethiopians use it or no, though.

There's actually two more new years in the Hebrew calendar: 15th of Shvat, the new year for trees, which is a minor holiday, and 1st of Elul, new year for beasts, which almost no one has ever heard about. Also at 9:42, you try to fast in Summer when it's 40 degrees outside.

[@SabaRaba1913]

ממתי לעזאזל יש חג בראשון לאלול Never heard about the 1st of Elul

[@shimmeringqueer9605]

in the Hebrew calendar, Adar is the month which is repeated and Adar bet(2) is the month that always happens.

In my country we still use the Julian calendar for religious purposes. For example we celebrate Christmas on 7th of January instead of 25th of December and we celebrate old new year on 14th of January.

[@therversonkanavathy7554]

@WonderWhy The Chinese and Indian calendar has their roots in the Tamil calendar. The epoch of the Tamil Calendar is said to be the start of recorded human history rather than a religious start of the world. Therefore it is interesting to research it further.

I never realised how dumb that 2012 hoax was till just now. Like I thought the Mayan calendar specifically put 2012 as the end of the calendar.

[@jayit6851]

Yeah media made it out to be the end of the the entire mayan calendar, not the ticking over of a friggen baktun...

[@joed72]

@@jayit6851 2020 was 2012 in the Ethiopian calendar...

remembered Mayans' calendar got misused to be "the end of the world on 21st December 2012"? that day was just a new year to Mayans.
