FAQ
How exact is the years, months, and days breakdown?
Age is computed from the birth date you enter to today (or a date you choose, if the tool offers one), accounting for calendar months and days—not just dividing by 365.
What if I was born on a leap day?
Leap-day birthdays are handled with normal calendar rules in non-leap years. For legal age cutoffs, follow the authority that defines your deadline.
Can I calculate age on a future date?
Use the tool’s date inputs if available to compare birth date against a target date such as an exam or visa day. Double-check official forms for their own age rules.
Is my data private?
Dates are calculated locally in your browser and are not uploaded to compute age.
