Your date of birth
The years figure is calendar-based — you turn N years old on your birthday, not after a fixed number of days. The total-days, total-hours, etc. are computed from raw elapsed time and update live every second.
We don't store the date you enter. Refreshing the page resets to January 1, 1990.
A note on counting
A person born on May 16 turns N years old on May 16 of year N + birth year — not after some fixed number of days. The total-days, total-hours, and total-seconds figures are the literal elapsed time since your birth instant (treated as UTC midnight on the entered date). They tick up every second.
