How to use the online alarm clock

An hour is a genuinely useful stretch for a proper rest, particularly for people doing shift work who need to sleep during the day before an overnight shift starts. It allows time to fall properly asleep and get a meaningful amount of rest, rather than the shallow doze a shorter nap provides.

It's also a common length for waiting on something specific — a load of washing on a longer cycle, a slow-cooked meal, or an appointment with a defined start time still an hour off. Because an hour is long enough to completely forget what you were originally waiting for, an alarm removes the risk of losing track entirely.

This preset sets an alarm for exactly one hour from the moment it's activated, with the finishing time calculated automatically.

Common questions

Why do night-shift workers often set an hour-long alarm?

It's a common length for a pre-shift nap, giving enough time to fall properly asleep and get some meaningful rest before starting work.
