Frequently asked questions
How is exact age calculated?
The calculator counts complete years from your birth date, then the complete months since your last birthday, then the remaining days — respecting the actual lengths of each month and leap years, so the result is accurate to the day.
How does it handle leap-year birthdays (February 29)?
If you were born on February 29, your age still increases once per calendar year. In non-leap years the birthday is treated as falling on March 1 for the countdown, which matches how most jurisdictions handle it.
Can I calculate age at a date other than today?
Yes — set the "as of" date to any day, past or future. That is useful for forms that ask your age on a specific date, like school enrollment cutoffs or eligibility deadlines.
Is my date of birth stored anywhere?
No. The calculation runs entirely in your browser and nothing you enter is sent to a server or saved.
