Calculate your exact age in years, months, and days.
Checking figures on paper takes time and invites small mistakes. Age Calculator takes date of birth and calculate age as of and gives an instant result you can recalculate with different values.
Most people know their age in years, but forms, exams, insurance and legal documents often need the exact figure in years, months and days on a particular date. Doing this by hand is surprisingly error-prone because months have different lengths and leap years add an extra day. This calculator does the date arithmetic for you.
The calculator subtracts the date of birth from the target date in three steps. It first subtracts the years, then the months, then the days. If the day of the month is smaller than the birth day, it borrows a month and adds the number of days in the previous month. If the month then becomes negative, it borrows a year. For example, from 25 November 1995 to 8 November 2026: years 31, months 11 minus … after borrowing it becomes 30 years, 11 months and 14 days.
A year is a leap year if it is divisible by 4, except century years, which must be divisible by 400. So 2000 and 2024 were leap years, while 1900 and 2100 are not. A person born on 29 February is counted by many authorities as turning a year older on 28 February or 1 March in non-leap years, which is a legal detail that differs by context, so check the rule of the body that asked for your age.
Beyond years, months and days, the same dates give total months, total weeks, total days and even hours lived. These make fun facts, for example celebrating your 10,000th day, which arrives at about 27 years and 4 months. You can also find out how many days remain until your next birthday and which weekday you were born on.
The dates you enter are processed only in your browser, so your date of birth is not uploaded or stored by this page. If you are calculating for a child, the same approach works; just enter their birth date.
To sanity-check a result, subtract the birth year from the current year and then subtract one if the birthday has not happened yet this year. That gives the age in completed years, which should match the first figure shown by the calculator. If it does not, re-check that the dates were typed correctly.
Government and school forms usually ask for age "as on" a specific date, not today's date. Enter that date in the second field and note the result in the format the form asks for, such as "25 years 3 months". When a form asks only for completed years, ignore the months and days. Keep a photocopy of your birth certificate or school leaving certificate handy, because the date printed there is what officials will verify, and a mismatch of even one day can cause a rejection. If you spot a wrong date on an official record, correcting it early is far easier than during an application deadline.
