Is there a scientific calendar which uses a different reference than Jesus? (lemmy.world)

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?

Barycentric Dynamical Time is one example of an astronomical time standard used in orbital dynamics models requiring consistency across billions of years and relativistic reference frames.
