Age Calculator
Find your age in years and total days.
How to use this tool
Choose a date of birth and a comparison date. The tool shows completed calendar years and elapsed days between the two dates.
What to know about the result
Day totals use calendar dates without time-of-day differences. Completed years increase on the month and day of birth. For a February 29 birthday, this tool treats March 1 as the anniversary in a non-leap year. Local legal rules can differ.
Frequently asked question
Can I calculate age on a future date?
Yes. Choose any comparison date on or after the birth date. The result describes the date you selected, not necessarily today.
