Timer in hours

00:00:00

How to use the online timer

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

Enter the number of hours, 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.

On public holidays such as Matariki, household routines may run later than they do on an ordinary weekday.

Check the clock, then begin.
