Age Calculator
Find your exact age in years, months, and days from your date of birth.
About This Tool
The Age Calculator works out an exact age from a date of birth to any reference date. It shows the age in years, months, and days, the total number of months and days lived, and how many days remain until the next birthday. It is handy for forms, eligibility checks, and curiosity.
By default the age is calculated as of today, but you can set any reference date. Everything runs in your browser.

Frequently Asked Questions
Can I calculate age on a future or past date? expand_more
Yes. Set the second date to any reference date, and the age is calculated as of that date instead of today.
How are months and days counted? expand_more
The calculator counts full calendar years and months first, then the leftover days, accounting for different month lengths and leap years.
Is my date of birth stored? expand_more
No. The calculation runs in your browser and nothing is uploaded or saved.
