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?
Id rather intersped the days as out of month days. 4 for the equinoxes and solsti but not sure where to put the fifth although I lean toward an extra one after the winter solsctice as the new year.
