Age Calculator
Current age in years, months and days from a birth date.
How it works
Subtract year/month/day with borrow, as on a calendar
Result is whole years + whole months + remaining days, by calendar arithmetic, not simple day division.
FAQ
Does leap year matter?
Yes — Feb 29 is handled by calendar borrowing; leap years are accounted for automatically.
Worked example
Born 1990-05-20, reference 2026-11-02:
Subtract component-wise: 2026−1990 = 36 years; 11−5 = 6 months; 2−20 = −18 days.
Borrow from the month (October has 31 days): −18 + 31 = 13 days, and months drop to 5.
Result: 36 years, 5 months, 13 days.
Notes and limitations
Age is calendar-based, not "days ÷ 365". People born on 29 February are usually treated as 28 February or 1 March in non-leap years, and institutions differ — follow the receiving authority’s rule for documents, pensions or school entry.
