FAQ
How is age calculated?
Using a calendar-accurate method: full years are counted first, then remaining full months, then remaining days — leap years are handled automatically.
Does this give the correct age for government forms?
Yes — this is the same standard calendar age used in forms, exams, and official documents (completed years as on date).
What about birthdays on a leap day (Feb 29)?
For people born on Feb 29, the next birthday counts as March 1 in non-leap years — the tool handles this automatically.
Can I calculate age on a future date?
Yes — enter any future date in "Age on date", e.g. your exact age on an exam's cutoff date.
