Frequently Asked Questions
How is age calculated?
Age is calculated as the exact difference between your birth date and today (or a chosen end date) in years, months, and days. Leap years and varying month lengths are accounted for.
Can I calculate age on a specific date?
Yes. Set a custom end date to calculate how old someone was (or will be) on a specific date. Useful for eligibility checks, anniversary calculations, and historical age verification.
Does it handle leap year birthdays?
Yes. If someone was born on February 29, the calculator handles leap year logic correctly for non-leap years, typically treating February 28 or March 1 as the birthday depending on convention.
What additional stats are shown?
Beyond years, months, and days, the calculator may show total days lived, upcoming birthday countdown, and zodiac sign. These are computed from the date difference.
Is my birth date sent to a server?
No. All calculations run in your browser. Your birth date is never uploaded or stored.
