Age Calculator
Exact age in years, months and days, plus your next birthday.
Age rules for legal and eligibility purposes vary by country — check the exact cut-off rule that applies to you.
How this works
Years = completed years between the dates
Months = completed months since the last birthday
Days = days since the last monthly anniversary
How do I find my age on a future or past date?
Fill in the "age as of" field. This is useful for eligibility cut-offs, exam applications and retirement planning.
How is age counted for a 29 February birthday?
In years without a 29 February, most legal systems treat 1 March as the anniversary. This calculator uses the same convention.
Does this send my date of birth anywhere?
No. The whole calculation runs in your browser. Nothing you enter is transmitted or stored.
