Find Your Exact Age
Enter a date of birth and this calculator shows the exact age in full years, months and days — the way ages are counted in documents and on birthdays. It also gives the age as a total number of months, weeks, days and hours, the day of the week the person was born and how many days are left until the next birthday.
By default the age is calculated for today, but you can choose any other date — for example, to find out how old someone will be on a certain day or was at an event. Everything is calculated in your browser.

Frequently Asked Questions
Is this age calculator free?
Yes, it is completely free and has no limits.
How is the age calculated?
The calculator counts the full years since the birthday, then the full months since the last birthday, then the remaining days. Months have different lengths, so the day count is measured from the same day of the last full month.
What about people born on 29 February?
In years without 29 February the birthday is counted on 28 February, so the next birthday and the age in years are always shown correctly.
Is my date of birth sent anywhere?
No. The calculation is done in your browser; nothing is stored or sent.
