Does a February 29 birthday mean you only age every four years?

No. You age every year, and the calculator counts full years, full months, and remaining days from your birth date.

Why does the calculator show March 1 in non-leap years?

Because February 29 does not exist in common years, the calculator places the next birthday on March 1.

Can I check my exact age on a past or future date?

Yes. Change the Age on field to any date to see how old you were or will be on that day.

Is my birth date stored anywhere?

No. Everything runs in your browser and nothing is sent or saved.
