How to use the online alarm clock

Twenty minutes sits comfortably in nap territory — enough time for a proper rest without tipping into a full sleep cycle that leaves you groggy on waking. It's also a common cooking length, covering everything from a batch of biscuits in the oven to a pot of rice on the stove.

It's a useful buffer length too, whether that's twenty minutes before it's time to leave for an appointment or twenty minutes to let something cool down before it's handled. Because twenty minutes is just long enough to properly lose track of time, setting an alarm beats trying to keep half an eye on the clock.

This preset triggers an alarm exactly twenty minutes from the moment it's set.

Common questions

Is 20 minutes better than 15 for a nap?

It's a personal preference — both sit within the recommended power-nap range, with 20 minutes giving slightly more rest time.
