FAQ
What does "Age on date" do?
It calculates your age as of any date, not just today — useful for eligibility checks (like "how old will I be on exam day") or working out someone's age at a past event.
Does it account for leap years correctly?
Yes — the calculation works from actual calendar dates, so leap years are handled correctly rather than assuming a fixed 365-day year.
Is my date of birth stored or sent anywhere?
No — the calculation happens entirely in your browser; nothing is saved or transmitted.
