Age Calculator

Enter your date of birth and get your exact age in years, months, and days. Also shows how many days you've been alive and how long until your next birthday. That number is either exciting or a little scary depending on your age.

How to use

  1. Enter your date of birth.
  2. The Age as on date defaults to today. Change it if you want to know your age at some other specific date.
  3. Your age in years, months, and days shows up along with total days lived and a countdown to your next birthday.
  4. Hit Reset to clear and start fresh.

An age calculator finds your exact age by comparing your date of birth with today, or any target date you choose. Beyond years, it tells you the remaining months and days, the total number of days you have been alive, the day of the week you were born, and how many days remain until your next birthday.

Age calculation looks simple but has edge cases: months have different day counts (28–31), leap years add an extra day, and the definition of 'one year older' shifts by a full calendar year. This calculator follows the standard Gregorian calendar convention used worldwide.

Frequently Asked Questions

How is exact age calculated?

The calculator counts full years from your birth date to today, then counts full months in the remaining period, and finally counts the leftover days. This matches how age is counted legally and in everyday use.

Can I calculate age between any two dates?

Yes. Set the birth date to any start date and the 'as of' date to any future or past date. This is useful for calculating the age of a document, contract, project, or historical event.

What if I was born on February 29 (leap day)?

In non-leap years, most countries legally recognise February 28 or March 1 as your birthday. Our calculator treats February 28 as the birthday in non-leap years.

What is the minimum legal age for common milestones in India?

Voting and driving: 18 years. Marriage (women): 18 years (proposed to be 21). Drinking alcohol: varies by state, typically 21–25 years. Senior citizen status for tax purposes: 60 years (super senior citizen: 80 years).
