About this page
Enter your date of birth, and optionally the time, to see how long you have been alive as a live counter of seconds, plus the total in years, days, hours and minutes. The count uses your device’s current time zone and updates every second.
Frequently asked questions
How is the number of seconds calculated?
It is the time elapsed from your birth date and time (midnight if you leave the time empty) to now, using your device’s clock and time zone.
Is my birth date stored or uploaded?
No. It stays in your browser and is never sent to time.foo.
Why might the result differ slightly from other calculators?
Different tools may assume a different birth time or time zone; adding your exact birth time gives the most precise result.
