Why use this age calculator?

Sometimes you need more than just your age in years. You may want to know your exact age in years, months, and days, check how old you were on a particular date, or find out how many days are left until your next birthday. This age calculator gives you all of these details in one place.

Here’s what you can find with the calculator:

  • Exact age: See your age in years, months, and days based on your date of birth.
  • Total time: View your age in total months, weeks, days, hours, minutes, and seconds.
  • Next birthday: Find out how many days are left until your next birthday and the age you will turn.
  • Age milestones: Check which major age milestones you have already reached and which one is coming next.

  2. If needed, change the Age at date field. It uses today’s date by default, but you can select another date.
  3. Click Calculate my age to see your complete age breakdown.
  4. Use the preset buttons if you want to quickly check the age for a specific number of years ago.
  5. Click Copy result if you want to save or share the calculated result.

An example

Suppose your date of birth is June 15, 1995 and the selected date is September 15, 2024. The calculator would show:

  • Age: 29 years, 3 months, 0 days
  • Total days: About 10,684 days
  • Total hours: About 256,416 hours
  • Next birthday: 273 days away, when you will turn 30

You can also change the selected date to a date in the past. This can be useful if you want to know how old you were when a particular event happened.

Useful tips

  • Try the preset buttons: They are useful when you want to quickly check the age of someone born a certain number of years ago.
  • Use a specific date: Change the Age at date field when you need to know your age on a past or future date.
  • February 29 birthdays: If you were born on February 29, the calculator handles leap years when calculating your age and birthday information.
  • Check important dates: You can use the calculator to check your age on birthdays, school or college dates, or other important events.
  • Keep the page handy: If you regularly need to calculate ages, you can bookmark the calculator for quick access.

A note on privacy

Your date of birth is personal information, so it is important to know how a calculator handles it. This calculator performs the calculation in your browser, so your date of birth does not need to be sent to a server just to calculate your age. Once you leave or refresh the page, the entered information is not intended to be stored by the calculator itself.

Age Calculator – FAQ

Yes. The calculator uses your date of birth and the selected date to calculate your age in years, months, and days. It also takes leap years and different month lengths into account. The smaller time units, such as hours and seconds, are based on the number of days between the two dates.
Yes. You can enter anyone's date of birth to calculate their age. It can be useful for checking a family member's or friend's age, or simply finding out how old someone was or will be on a particular date.
The "Age at date" field lets you calculate an age for a specific date instead of today. You can choose a date in the past or future to find out how old someone was or will be on that day.
The calculator handles February 29 birthdays when calculating your age. Since February 29 does not occur every year, the way a birthday is observed in a non-leap year can depend on the purpose or local convention. The calculator still uses the actual birth date when working out your age.
The calculator looks for your next birthday based on your birth month and day. It then calculates how many days are left until that date and shows the age you will turn on your next birthday.
The fun facts are based on general estimates rather than personal measurements. For example, estimated heartbeats or breathing counts use average rates over time. They are included for interest and should not be treated as medical or scientific measurements.
The age calculation is performed in your browser, so your date of birth does not need to be sent to a server for the calculation itself. However, your browser or other website features may have their own storage or data policies. For privacy-sensitive information, avoid entering details you do not want to share online.
The calculator is useful for everyday age calculations, but it should not replace official documents. If you need to prove your age for legal, medical, government, school, employment, or other official purposes, use the date of birth shown on your official records and follow the rules of the relevant authority.
