Age Calculator
Find an exact age and how many days until the next birthday.
How age is counted
Your age in years goes up on each birthday. For an exact figure, the calculator counts whole years first, then whole months, then the remaining days since the last monthly anniversary of your birth date.
What you get
- Your age in years, months and days.
- The total months, weeks and days since birth.
- The number of days until your next birthday.
Use it for other dates
Change the second date to find a person’s age on any day in the past or future, such as a school cut-off date or a milestone. It can also tell you how long ago any event happened.
Frequently asked questions
How are leap years handled?
Calculations use real calendar dates, so leap days are counted in the total days.
Is the day of birth counted?
The calculator counts the days elapsed between the two dates, so your birth date itself is day zero.
