Frequently asked questions
Why not just divide days by 365?
Leap years and unequal months make that drift. Calendar borrowing gives the legally and culturally correct age.
Can I compute age at a past or future date?
Yes — set the "as of" date to anything: visa forms, school cutoffs, retirement dates.
How are leap-day birthdays handled?
Feb 29 birthdays roll to Mar 1 in non-leap years for the next-birthday countdown.
