How is age calculated?

Age is calculated by finding the difference between your birth date and the current date (or a specified date), accounting for years, months, and days.

Can I calculate age for a specific date?

Yes! You can change the "Calculate age as of" date to find out how old you were or will be on any specific date.

What does "Next Birthday" mean?

This shows the day of the week and date of your next birthday, plus how many days remaining until then.

Is my birthdate stored?

No! All calculations happen directly in your browser. Your birth date is never sent to any server or stored anywhere.
