How it works
The difference between the birth date and the chosen date is counted in full calendar years, then months, then remaining days. Total days and the countdown to the next birthday are also shown.
Example
Born on 15 May 1990, on 7 November 2026 you are 36 years, 5 months and 23 days old.

How are leap-day birthdays handled?
For 29 February, the next birthday in a non-leap year falls on 1 March.

Is the time zone relevant?
Dates are compared as calendar days, so time zones do not affect the result.
