Age Calculator — Exact Age in Years, Months, and Days
Find an exact age from a date of birth, accounting for leap years and varying month lengths. Useful for forms, eligibility checks, and milestones where "about X years" is not precise enough.

Age Calculator — Frequently Asked Questions
Got questions about Age Calculator? Here are clear, honest answers to the most common questions about pricing, privacy, compatibility, and features.
Does the Age Calculator account for leap years?
Yes. It correctly counts February 29 in leap years and handles months of different lengths, so the day count is exact rather than an approximation.
Can I calculate age on a future or past date?
It calculates age as of today by default. The difference is measured in completed years, months, and days from the date of birth to the current date.
Is my date of birth stored anywhere?
No. The calculation runs entirely in your browser and the date you enter is never uploaded, logged, or shared.
Why does my age in days seem high?
A single year is about 365.25 days, so even a few decades adds up to many thousands of days. The calculator shows the precise total based on actual calendar dates.
