Enter your birth date to see your exact age, right down to the day.
Your age is worked out by comparing your birth date to today's date, counting full years first, then the leftover months, then the leftover days. This is the same method used on official forms and ID applications, so the result matches what you'd get by counting on a calendar by hand.
Because a full year only counts once your birthday has actually passed this calendar year. If your birthday hasn't happened yet this year, your age in "full years" is still one less than the current year minus your birth year.
Yes. The calculation uses real calendar dates, so leap years (like February having 29 days) are automatically handled correctly without any extra steps.
No. The calculation happens entirely in your browser — your date of birth is never sent to or saved on our servers.
