I hope questions are allowed here. I am curios if there is a different sort of scientific calendar which does not use the birth of Jesus as a reference like AD and BC. For example Kurzgesagt’s calendars use the the current year plus 10000 as this represents the human better or something like that.
Would there be a way to do this more accurately? How could we, in a scientific correct way, define a reference from where we are counting years?
Also I have read about the idea of having 13 months instead of 12 would be “nice” because then we could have a even distributed amount of days per month.
Are there already ideas for this? What would you recommend to read?
You can also make a quarter align with the seasons, so you can just call it spring, winter, …
You can also keep 12 months and make them 30 days each, and add an equinox day in between the seasons. Winter solstice has new year tacked to it and in a leap year summer solstice is two days with the leap year. Keeps it all nicely aligned with the sun.
If you really want you can do weeks of 6 days so each month comes down to exactly 5 weeks of 6 days so the calendar is perfectly reusable each year.
Doesn’t the Southern hemisphere experience winter when we have summer?
Yeah but with the 7 day week you only have 1 or two intercalaries to figure out
6 day weeks leave you with five or six, and having almost a week on average of extra days to make work feels like too much of a nuisance just to be able to keep a unit of measure that doesn’t really serve any actual specificity that you can’t get with the Q-W-D format date.
