About the Age Calculator
An age calculator works out the precise time between your date of birth and today — not just the number of years, but the exact months and days too. It is useful for forms, eligibility checks, or simply satisfying curiosity.
This calculator runs in your browser and accounts for varying month lengths and leap years, so the result is accurate. It also tells you how many total days you have lived and counts down to your next birthday.
Frequently asked questions
Does it account for leap years?
Yes. The calculation uses real calendar dates, so leap years and different month lengths are handled correctly.
Is my date of birth stored?
No. The calculation happens locally in your browser and nothing is saved or sent anywhere.
