How to use the online timer

A countdown in seconds is useful when the duration matters more than the clock time.

Enter the number of seconds, check the displayed finish, and press start when the activity actually begins.

If the browser sleeps, the battery runs low, or the device is muted, the alert may be missed, so keep another cue for anything safety-critical.

Elapsed time does not change when daylight saving starts or ends, although the clock shown at completion may jump during that overnight change.

Use a quiet alert on public transport or in a library, and never handle the timer while driving.

Because mains power is 230 volts, keep a plugged-in device clear of steam and wet benches.

Check the clock, then begin.
