Age Calculator
Your exact age in years, months & days.
Runs entirely in your browser — nothing you enter is uploaded, logged, or tracked.
Enter your date of birth to get your exact age down to the day — plus the total number of months, weeks, days, hours and minutes you have been alive, and a countdown to your next birthday. Nothing is sent anywhere.
Frequently asked questions
How is my exact age calculated?
It counts full years from your birth date to the target date, then the leftover months and days — borrowing days from the previous month where needed — the same way you would say “32 years, 4 months and 9 days”.
Can I calculate age on a future or past date?
Yes. Change the “age at” date to any day — a future birthday, a historical date, or today (the default) — and every figure updates.
Are leap years handled?
Yes. The counts use real calendar dates, so leap days and varying month lengths are accounted for automatically.
Is my date of birth stored?
No. The calculation runs entirely in your browser; your date of birth is never uploaded or saved.
