Missed opportunity to say that the Mayans managed to keep track of dates for so long because they used Skillshare

@InterKELLar

My brother is a leap year baby. He'll be 36 soon but only has 8 birthdays so far. So technically  my 10yo is older than him.

One last video before the year is out, and an appropriate topic – calendars. Like my last video, this is a video I have been wanting to make for some time now. I start by looking at the transition from Julian to the Gregorian calendar, before looking at some traditional calendars from around the world and throughout history.

@Ivienen

You didn't mention the decimal calendar that was used in the French revolution

@thelaniakean

Now we need a galactic calendar for earth’s orbit around the Milky Way

Imagine the people that were born on February 30th in Sweden, they would never have they're birthday's.

@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.

@peachykeen3194

The little things are what make your videos so good, like how you zoomed in on the monthly calendar on the lower right when talking about the 9th month of the Islamic calendar because Arabic is written right to left. Or maybe I'm just reading too much into it.

COINCIDENCE? I THINK NOT

@revinhatol

And that's how BoBoiBoy celebrated Ramadan and started Syawal in a big way, from the first day (of August) all the way to Malaysia's 54th Day of Nationhood.

@OktaSila

The Balinese calendar or also known as the "Çaka calendar" consists of 35 days in a month and 12 months in a year. The new year celebration is called "Nyepi Day".

@Ken19700

Under the Chinese calendar I'm a dog.

@nikkifrozen3814

What about indian and Persian calendars

@sophia.e.cooper
