Frequently Asked Questions
How is age calculated?
Age is the difference between the date of birth and today, counted in completed years, months, and days. Someone born on March 15, 1990 turns a year older each March 15 — not on January 1.
Does the calculator account for leap years?
Yes. It uses the actual calendar, so February 29 birthdays and leap years are handled correctly.
Can I calculate the age difference between two people?
Yes. Enter each person's date of birth and subtract, or use the date-difference calculator in the same category for the gap in years, months, and days.
Is my date of birth stored?
No. The age is computed in your browser from the date you enter, and nothing is saved or sent anywhere.
