Frequently asked questions
How is exact age calculated?
Full years are counted first, then full months, then remaining days, using the real calendar, including leap years.
What if I was born on February 29?
In non-leap years, the calculator treats March 1 as the birthday for the next-birthday count, which is a common convention. Some people celebrate on February 28 instead.
Does it use my time zone?
It uses calendar dates only, so the result is the same in any time zone for the dates you enter.
Can I calculate the age of a child or a pet?
Yes. Enter any past birth date and the calculator returns the age on today's date.
