What is Age?
Age is calculated as the difference between your date of birth and today. This calculator handles calendar quirks like varying month lengths and leap years so the result matches official forms (passport, PAN, exam applications).
Formula
Years = current year − birth year (adjusted if month/day not yet reached) Months = current month − birth month (adjusted if day not yet reached) Days = current day − birth day (borrowed from previous month if negative) Days until next birthday = (next birthday date − today) in days
How to use this calculator
Pick your date of birth in the calendar input. The breakdown shows completed years, months and days, plus how many days remain to your next birthday. Useful for filling exam, visa or insurance forms that ask for age in years and months.
