The oXben Age Calculator tells you your exact age in years, months, days, hours, and minutes — instantly. Enter your date of birth and the tool calculates how long you have been alive down to the minute. It also shows your next birthday countdown, the day of the week you were born, your Western and Chinese zodiac signs, your generation label, and your age on every planet in the solar system.
The Date Difference section lets you measure the gap between any two calendar dates — useful for project planning, event countdowns, or historical research. All calculations run entirely in your browser; no data is sent to any server.
Is this age calculator accurate?
Yes. It calculates age using your local system clock, accounting for leap years, varying month lengths, and day-of-month offsets. The result matches civil age in all common jurisdictions.
Does it store my birth date?
No. The calculation runs only in your browser and the date is never transmitted or stored anywhere.
