“This year minus my birth year” gets you close, but it's usually wrong by up to a year — it ignores whether your birthday has happened yet. And months don't all have the same number of days, so a precise age has to walk the actual calendar. This calculator does that, leap years included, so the years-months-days figure is exact.
Your exact age is the difference between your date of birth and today, expressed in years, months and days. This calculator handles the tricky parts — different month lengths and leap years — so the result is precise, not just today’s year minus your birth year.
Enter the birth date and set the second date to any point you like. The calculator returns the full age at that date. This is handy for working out how old someone was on a past event, or will be on a future one.
The calculator shows your total age in days, weeks and months as well as years. Total days is the exact count between your birth date and the chosen date, including every leap day along the way.
Yes. It counts the real calendar difference between the two dates, so leap days are included automatically in the total-days figure and the year/month/day breakdown.
