Age Calculator
Exact age in years, months and days, total days lived, the weekday of birth, and the countdown to the next birthday.
Example — Born June 15, 1990 — age on October 13, 202636 years, 3 months, 28 days old
How we got it — the example, step by step
- Subtract the dates part by part — years, then months, then days — borrowing a month of days when the day count goes negative.
- Total days lived: 13,269 — that is 1,895 full weeks and 4 days.
- Born on a Friday. Next birthday: June 15, 2027, in 245 days.
Check it backwards
Add it back: June 15, 1990 + 36 years + 3 months + 28 days = October 13, 2026 — the 'as of' date.

Why can two age calculators differ by a day?
Time zones and the hour of birth. This one works in whole calendar days — your legal age changes at the start of your birthday in most places, and the page counts that way.
