How is age calculated?

We count completed calendar years from your birth date to the chosen date, then the leftover months and days. For example, someone born 1990-06-15 is 33 years, 0 months and 0 days old on 2023-06-15.

How is a Feb 29 birthday handled?

For the next-birthday calculation in a non-leap year, a Feb 29 birthday is treated as Feb 28. The exact-age count itself is unaffected.

Can I calculate age at a past or future date?

Yes — change the 'Age at date' field. It defaults to today, but you can set any date to find someone's age then.
