Why Do Some Countries Use Different Calendars?

▶ In this video I talk about the different calendars that exist throughout the world. I explain how, in general, calendars are categorized as either being Solar, Lunar, or Lunisolar; with the first being related to the position of the sun, the second related to the position of the moon, and the third related to both. I list some of the more well known calendars in each of these categories - such as the Chinese calendar, the Hebrew, the Islamic, or the Indian National Calendar - explaining in which circumstances they are used and understanding how most of the world, save a few exceptions, has adopted the Gregorian Calendar as its main civil calendar, using local ones for cultural and religious purposes only.

Some exceptions as always. My country is really hot (the Dominican Republic) and we use a solar one.

[@espvp]

@@raycedano hi, fellow dominican. OP is speaking in the sense of historical origins. We use the gregorian calendar, like much of the world, because that's what the europeans established during colonization. In our case, had the indigenous people (Tainos) created a calendar before European contact, it would've been different to the gregorian calendar we all know. Though I would hypothesize that it would still be a solar calendar given that here in the Caribbean we do have distinguishable seasons, just not the traditional ones in europe, north america and other regions of the world (winter, spring, summer and autumn); we have only two season --rainy and dry-- that do repeat on a yearly cycle, hence, would've still been a solar calendar, but focused to keep track of those two seasons instead. Regardless, Tainos probably didn't have a calendar because they never needed one in the first place, simply because they weren't an agricultural society (yet) and the few produce they did collect was available _mostly_ throughout the whole year. So no point for them on keeping track of the seasons, which circles back to OP's theory, where they are making the observation that societies that did got to create their own calendars but whose environment didn't pose significant changes throughout the year, then those societies created calendars that weren't linked to the sun, i.e., to the yearly seasons, but instead a moon-based would suffice.

Some time ago, the Finnic peoples used a calendar system whose time calculation was tied to and based on the cycle of nature. For example, the year changed at the end of the harvest season and winter began when snow fell on the ground and summer began when the snow melted and etc. There are still signs of that agriculture-centered system in Finnic tradition and culture, even though the Gregorian calendar is used in Finland and Estonia today.

The Japanese also use an era calendar, generally named for the emperor, and starting with year 1. Thus Showa 1 was 1926 when the Emperor known as Hirohito was enthroned; I remember it as just adding or subtracting 1925. Some emperors also would come up with a new era name after a string of calamities, such as famine or earthquakes. The details of choosing it over the Gregorian are beyond my experience.

[@kamikazeviking3053]

The actual year is the same as the Gregorian calendar with the only difference being that the 1st year being when a new emperor takes up the throne. This also means that the first and the last year of the era are shorter than the rest, so if a new everyone takes the throne in October, the 1st year of the era only lasts for 2 months and it becomes the second year on January 1st of the Gregorian calendar.

The Maya/Aztec calendar is particularly fun because the 260 year cycle means it’s never remotely in sync with solar calendars. It also means you “age” faster because birthdays occur more often. It has a “zodiac” of 20 animals/natural forces that takes 20 days to cycle through, plus a number for each day that resets after 13. My birthday in this system for example is Two-Dog. There are exactly 260 combinations of numbers and symbols because the two cycles won’t arrive at the same combo until 260 days later.

On the subject of naming of years, some calader systems start a new "era" when the ruler of the country changes. Some examples are Japan and the UK. Often these are only used for official archiving purposes. It is hard to write dates in the future when you don't know if that future date will still be in the same era as the current date, so these kind of systems are mostly for recording things as they happen, or when referring to events in the past.

Actually the Julian and Gregorian calendars also include a luni-solar component: The date of Easter is set to be the first Sunday after the first full moon following the 21th of March (because the day of the crucification is assumed to be either the 14th or 15th of Nisan in the Hebrew calendar). This influences also all holidays of Christian origin for which the date depends on the Easter date, like Passion Week, Pentecost, and Carnival. Most of Eastern Christianity however still uses the Julian calendar to determine the date of Easter, so the date will differ in most years from Easter in the Gregorian calendar (by a week in most years, but in some years up to 5 weeks, like in 2027).

In the Hebrew calendar, every month begins once there is a new moon. Also, every day begins when the sun starts to set. This is because the first chapter of the book of Genesis states: "ויהי ערב ויהי בוקר יום אחד", which translates to: "And there was evening, and there was morning-the first day." From this, we can infer the first part of the day is the evening, and after that comes the morning. Hope this is insightful. Maybe make a video about the Hebrew calendar.

The Sunday is a day where all banks and governments offices are closed. For this a working shift is normally 10 till 12 hours and at morning at 8 and evening at 6 sounds the national anthem hymn of the Kingdom of Thailand. The King of Thailand have own anthem hymn! Most Thai folk use thai calendar so mostly if ask born date they follow to ask "How old are you?". 🤗

my favourite one is Coptic - 13 x 28d months (=364) with 1 or 2 days for leap year (365 or 366) - in the 'west' we could put the leap day at Christmas/New Year 🙂

In the Hebrew Calendar, a day begins at sunset and ends with three stars. And, like the Chinese one, a month starts with a new moon. Also, it is actually an ancestor of the Babylonian and Assyrian calendars; the names of the months are of Akkadian origin.

[@General.Knowledge]

Very interesting! Are they ancestors with a direct connection? Or do they just happen to measure things in a similar way?

About the Iranian (aka jalali) calendar It start at the moment (not the day) of spring equinox (first day of spring usually is March 21 or 20) as the resurgence of nature. Despite it known as an Islamic country, the months have the names of 12 angels of the Iranian ancient Faith (before 7th century), the zoroastrianism. First six months have 31 day, the subsequent 5 have 30, and the last month has 29 (30 in leap years)

10:09 You forgot about juche, but that Calendar system is the Gregorian one, but the 1 was Kim Il-sung's birthday. (1912). There was no BC for 1911. (I guess)

[@Liggliluff]

Weird usage of "BC" since it still means "before Christ" and using "BCE" would also not work, because it stands for "before common era". It would be either BJ (before Juche) or BJE (before Juche era)

Interesting also to note that about a third of countries start the week on Sunday compared to 2/3 on Monday and a handful even start the week on Saturday

[@General.Knowledge]

Very interesting too! Although I feel like in a lot of cases the Sunday start is more of a formal thing than a reality. Here in Portugal I think it technically starts on Sundays but in reality it's Mondays.

[@StuTun]

@@General.Knowledge Actually my friend in Algeria begins his 5 day working week on Sunday, as Friday is their most holy day, and Saturday is seen as the rest of the weekend for him.

[@Liggliluff]

@@General.Knowledge And due to Portugal officially starting on a Sunday, yet follows the same 4-day rule for which is week 1, that means that 1 out of 7 years, Portugal will be out of sync with the rest of Europe for which week is week 1. This happens every year starting on a Thursday, so next time this will be 2026. Week 1 is 29 Dec to 4 Jan in Europe, while week 1 is 4 Jan to 10 Dec in Portugal instead, which is week 2 in Europe.

Chinese calendar has three dimensions for cycles. Traditionaly, the sexagenary cycle is the most important and the most common, which is a 60 year cycle denoted using two chinese characters. Then there is the zodiac, the 12 year cycle. Historically the emporor will select a name and Chinese will add this name before number to indicate year, such as "Tianbao 5 year". After a couple years if a new emporer reign or some event occur, a new word is used to start a new age. This method is still used in Japan and Taiwan.

Until the 15th century (1420 if I’m not mistaken) Portugal was the only country still using the Caesarian age calendar, so every date before the year of the change is 38 years displaced

I would like to add the Quechua\Aymara calendar used in festivities by the indigenous communities of the Bolivian, Peruvian, Chilean and Argentinian Andes, which is solilunar. The moon has 13 "periods" of 28 days each, and the sun has 8 months of 30 days and 4 of 31 days for a total of 364 days, plus an additional day called "Jach'a Uru", which is both the shortest and coldest day of the year, and also the transitional day from a year to the next. The festivity of the new year happens every 21 of June and is called "Willkakuti" and represents the end of the harvest season and the beginning of a new agricultural cycle. The biggest ceremony happens in the ruins of the ancient city of Tiwanaku, nearby the Titicaca lake in Bolivia. There, indigenous priests (and also tons of tourists) gather each year to wait for the first rays of the sun to come through an ancient monolith called "Gateway of the sun", which used to serve as solar calendar to the pre-inca Tiwanaku civilization. In this system, the Gregorian 2023 will be year 5531, or year 531 of the 5th era (each era is 1000 years). This linear way of counting years is modern (in the old times it was cyclical) and more political than religious. It is the years that has passed since the arrival of Columbus to the Americas in 1492 plus 5000 years, which is more or less the amount of time that some indigenous scholars and philosophers think the old Andean civilizations thrived before being crushed by the European invasion.

New calendar 1: Keyword: Baha’i - 19 months, 19 days per month, 4 or 5 day intercalery festival includes February 28 (29) so that the Baha’i calendar consistently matches the Gregorian calendar. New calendar 2: Keyword: Lotus 1 2 3 - each day has a number starting with day 1 a long time ago (no years, no months, no weeks); the calendar subroutine converts the day number into the format chosen by the user. This is very convenient for calculating elapsed time in days. You may tell me I am mistaken or add details as you choose.

[@toms5996]

What I find interesting is that as late as 1788 (and even in 1998) in Europe Metric time was proposed. Think about it: our current time is quite strange - a 12+12 based system for hours and a 60 based for minutes and seconds - also how months are 'scheduled' to 12 is interesting. A Metric system would have solved everything - dividing the day into 10 hours or 1,000 minutes, each new hour into 100 minutes, each new minute into 1,000 seconds. Year being 10 months. This might seem strange to hear suddenly but think about our current time management a bit more - you knew of course that the the daily time is around 2000 years old based on very 'interesting' things and the yearly time 4000 years old based on Egyptian solstices + gods.

The day for Easter each year is determined using a luni-solar calendar that merges the metonic cycle and the Gregorian/Julian calendar depending on tradition.

[@ayoubgourram9011]

In Morocco, The gregorian calendar is used in almost every situation. But also the Hijri calendar is used for Religious events and in schools as well.. In Subjects like ( Islamic Education and Arabic) teachers tend to use both the gregorian and the Hijri calendars... Also the Berber calendar is used but i might say that it's only celebrated but not used in formal situations... Berber people celebrate the new Berber or Amazigh year each year as a symbol of pride and identity.

There is another such "ceremonial" calendar that is actually used to this day throughout most of the Western world - the Computus, which is used to calculate the date of Easter (and related dates such as Pentecost, Fat Friday and so on). While Easter is theoretically based on the spring equinox and the new moon, it's actually calculated using this special calendar created by the Catholic Church (which does line up very well with the aforementioned celestial phenomena).

The Julian calendar is still used in Eastern Orthodox countries now mostly for religious reasons but it's not that they don't know it's wrong (the year is not quite 365.25 days), it's just that Pope Gregory had no business reforming the calendar. In a couple of centuries, it'll be 14 days out. BTW Bolivia has recently attempted to revive a pre-columbian calendar.
