How this calculator works
Find exact age in years, months, and days — plus next birthday milestone and total time lived.
How is it calculated?
Calendar difference from birth date to the “as of” date in years, months, and days. Totals use exact day count (leap days included).
Example
Born Aug 11, 1990 as of Aug 11, 2026 → exactly 36 years.
Frequently asked questions
How is age calculated?+
We subtract the birth date from the “as of” date in full years, then leftover months and days.
Does it account for leap years?+
Yes. Total days use the actual calendar span, so Feb 29s are included when they fall between the dates.
Time zones?+
Uses calendar dates at local noon to avoid DST edge cases.
