FAQ
How does it count leap years?
Native Date object with the full rule: every 4 years is leap, except those divisible by 100 unless also divisible by 400. So 2000 was leap, 1900 wasn't.
Does my age change when crossing time zones?
Dates are handled in your local time zone. Switching zones may shift age by a few hours but not days.
Useful for gestational age?
Yes. Enter the last-period or conception date and get weeks + days in the standard obstetric format.
Pre-1900 dates supported?
Yes, no problem. Works fine for genealogy.
