France tried such calendar in 1789 and 1871. We lost it when Jules Ferry executed all the communalists in Paris. Some people in France still use those calendars to show their support to revolutionary ideas
There are a few websites and twitter accounts that remind you that today is Nonidi, 29 Germinal of the year CCXXXII.
Picking up a newspaper in Thailand reminds you it’s year 2567


The reckoning of the Buddhist Era in Thailand is 543 years ahead of Anno Domini, so the year 2024 AD corresponds to B.E. 2567.
As a software dev who has lost weeks of his life dealing with timezones, leap days, daylight savings time, date math and other associated nonsense I fully support this being the way the world is. I don’t want to go through the transition to get there though
Developers are the only people against DST changes, just because of how complex it will get. Dear God cities are removing DST! Cities! It means I need to know if you are in or out of a city to know if you need to be shown daylight or standard time!
Just please do it nationally yes or no
Write everything in UTC, cast to local time zone for UIs
Life problems solved

That’s why it’s lucky that identifiers in the tz database are already things like
America/New_Yorkinstead of “eastern time.”
Bad news: this has nothing to do with timezones, leap days nor daylight saving time. Honestly, leap days would be worse because they wouldn’t be part of the 7 day week
Just make them holidays, everyone works too much anyway, and it’s just getting worse for no reason.
It’s accounted for just like any other leap year, add it to the end of a month as a universal holiday. Most calendar models make it July 29. It’s also worth noting that this is actually 364 days, and a single day at the end of the year is a universal holiday.
Edit: I think leap years should be at the end of the year too for simplicity.
Which breaks “day of week = day modulo 7” if every month starts on Monday and not every month has the same number of days
In this scheme, new years day and leap days are not any day of the week or part of any month. They exist outside of the regular calendar as obvious and explicit resets to the remainder problem.
Look, short of changing Earth’s orbit, something’s not gonna line up no matter what you do. Extra-weekly days are as good a compromise as any in my book.
There is also a technological solution, I knew it
But how would the corporate world divide the 13 month year into quarters? Don’t you know what that’ll do to the bottom line?! Think of the poor shareholders! /s
A lunar day is 27.3 days and a solar cycle is 29 and change. So we’d be just off the lunar cycles. Like when you’re sitting waiting for a turn lane signal to change and the person in front of you has a blinker that’s just a tiny bit slower than yours.
Yeah sadly the rotations of Earth around its axis, the moon around Earth, and Earth around the sun don’t divide each other nicely
Why would god do this
We should divide the year into four suits — one for each season. Each suit is thirteen weeks long, numbered ace to king. Sometimes we have a Joker day.

I do not want my birthday to fall on the same day of the week each year!
This reminds me of a fantasy series I like, where the world still has 365 day, but every month is 30 days long, and the remaining 5 days are separate holidays for the solstices, equinoxes, and new years.
Also, when are we going to do 10hrs/day, 100 min/hr and 100s/min?
Don’t decimalize time, instead dozenalize our numbers! Twelve is such a better building block than ten. Pretty much all math becomes way easier using dozenal numbers instead of decimal ones.
With base 12 you can actually get a result for 1/3
Also, when are we going to do 10hrs/day, 100 min/hr and 100s/min?
This is how you collectively give the entire scientific community a simultaneous aneurysm. The amount of work needed to convert measurements based on our current seconds/minutes/hours to your “metric” seconds/minutes/hours would be astronomical.
Also, pretty much everyone already agrees on the current system of time, so why change it? It would just create another metric/imperial or F/C divide and cause conversion mistakes.
