How to Calculate Your Exact Age From Date of Birth

Forms, applications and eligibility checks often need your exact age — not just the year. A quick calculator gives you years, months and days, and doubles as a date-difference tool.

Find your age in 2 steps

1. Open the Age Calculator and pick your date of birth.
2. The result shows your exact age plus totals and days to your next birthday. Change the 'age at date' to check any past or future date.

Nothing is stored or uploaded — the calculation runs entirely in your browser.

Set both dates to any two days and it works as a simple date-difference calculator too — handy for counting notice periods, deadlines and anniversaries.
