So, Theory about this

The Fan-Ball Timeline years are all 366 days in total. January, March, May, July, September, and November have 30 days, while February, April, June, August, October, and December have 31 days, thus putting together a relatively even base for the years

As custom, each day is 24 hours, each hour is 60 minutes, each minute is 60 seconds, etc.

Possibly in the future, tho, if we want to, we can change this system into something less Earth-like in quality, possibly to something else, tho I think this would require figuring out accurate dates for everything that happens first, so
