Up to 100 laps and seven days per duration. This browser timer is not calibrated timing equipment and cannot alert after the page is closed.
Elapsed timing uses a monotonic browser clock. Duration countdown tracks elapsed time rather than subtracting assumed interval ticks. No audio or notification permissions are requested.
A 60-second duration counts down from 00:01:00.
