Calculate your exact age in years, months, and days

About this age calculator

How is age calculated?

Age is calculated by subtracting your birth date from today's date. The result accounts for leap years and varying month lengths to give you an exact count of years, months, and days.

What is my age in days?

Multiply your age in years by 365 and add the extra days — or use the total days counter above which calculates it precisely including leap years.

When is my next birthday?

The calculator shows exactly how many days until your next birthday based on today's date.
