Frequently asked questions


Does the calculator account for leap years?
Yes. Leap year handling is included in the calculation so ages are accurate regardless of birth date.


Can I calculate age on a specific past or future date?
Yes. Enter a target date instead of using today to calculate how old someone was or will be on that date.


Why is my age showing as one year less than expected?
If today is before your birthday this year, the calculation correctly shows you have not yet completed that year. You turn that age on your birthday, not on January 1.


Can I calculate time between two dates other than a birthday?
Yes. Enter any two dates to calculate the time elapsed between them.


Is my birth date stored or sent anywhere?
No. Everything runs locally in your browser. No data is transmitted.


What is the youngest age that can be calculated?
Days-old infants can be calculated. The output shows years, months, and days for precise age tracking.
