About the age calculator
This free age calculator tells you exactly how old you are — in years, months, days, and even live-ticking hours, minutes and seconds. Enter your date of birth (adding the time of day makes the live counter even more precise) and your age is worked out instantly, right in your browser.
It’s the easy way to answer “how old am I?” down to the second, count the total number of days you’ve been alive, or check your age on any given date.
How do I calculate my exact age?
Enter your date of birth above and the calculator instantly shows your age in years, months and days, plus a live count of the hours, minutes and seconds since you were born.
How many days have I been alive?
Along with your age, the tool shows the total number of days, weeks, hours and seconds you have lived so far.
Is the age calculator free?
Yes — it’s completely free, needs no sign-up, and everything is computed privately in your browser.
