Age calculator

About the age calculator

Enter a date of birth and get your exact age, the time you have lived, a live countdown to your next birthday and a few fun facts, without sending anything anywhere.

Calculate your exact age

Type your date of birth to see your exact age in years, months and days, today or on any other date you choose. It is handy for a form, a registration or an age requirement, such as checking how old someone will be on the day of an event.

Your life in numbers

The same age is also given as a total of months, weeks, days and hours, and the hours keep counting live. The tool also tells you which day of the week you were born, and shows your zodiac sign, your Chinese zodiac sign and your generation. Zodiac dates can shift by a day at the edge of a sign, and the Chinese sign follows Chinese New Year, which falls between late January and mid February.

Birthdays and milestones

A countdown shows how long is left until your next birthday, with the share of the year already gone. Round dates, such as your 10,000th day or your first billion seconds, are good excuses to celebrate, and a grid shows your age every five years. Anyone born on 29 February celebrates on 28 February in years that are not leap years: that is the rule this tool uses.

Nothing is saved

The calculation runs in your browser. The date you enter is never sent anywhere and is not saved: close the tab and it is gone.
