Frequently asked questions
How do I calculate my exact age?
Subtract your birth date from the target date, carrying days and months where needed. This calculator does it precisely — years, months, and days — and also shows total days and weeks lived.
Does it account for leap years?
Yes. It uses real calendar dates, so February 29 and varying month lengths are handled correctly.
Can I calculate age on a future or past date?
Yes — change the "age at" date. Leave it as today for your current age.
Is my date of birth uploaded?
No. TryCalculatingNow computes entirely in your browser. Your date of birth never leaves your device.
