What is Age Calculator?

An age calculator works out how old someone is on a given day, down to the month and the day, and counts the days until their next birthday.

What this tool does

Takes a date of birth and a second date (today if you leave it empty) and shows the age in years, months and days, the total months and days, and the next birthday. A birthday on 29 February is counted on 28 February in years without a leap day.

How to use it

  1. Enter the date of birth.
  2. Leave the second date empty for today, or pick another date.
  3. Read the age and the next birthday.
