Calculate exact age from a birthdate in years, months, and days. Also see total months, weeks, and days lived. Free, instant, in your browser.
Enter your date of birth and the date you want to check against (today by default). The tool counts full years, then remaining months, then remaining days — the same way you'd count by hand, but instantly.
Yes. The calculation works directly with calendar dates, so leap years and varying month lengths are accounted for automatically. The totals (months, weeks, days, hours) are derived from the exact difference.
Your birthdate is processed entirely in your browser. It is never stored or sent to a server.
