Frequently Asked Questions

How is age calculated?

Age is calculated by subtracting your date of birth from the current date, giving you the exact number of years, months, and days you have lived. Our calculator also shows your age in total months, weeks, days, and even hours.

Does the age calculator account for leap years?

Yes. The calculator correctly handles leap years, including February 29, so the day count is always accurate no matter which years your age spans.

Can I calculate age between two specific dates?
