FAQs
How are leap-year birthdays handled?
If you were born on 29 February, your birthday in other years is counted as 1 March.
Can I find my age on a past or future date?
Yes. Change the 'Age as of' date to any day after your birth.
Why do months have different day counts?
Leftover days are counted against the actual length of the previous month, so results match the calendar.
