How to use the online alarm clock

A quarter of an hour is the classic short-nap length. Sleep researchers tend to point at ten to twenty minutes as the window that leaves you refreshed rather than groggy, because it stops short of deep sleep — fifteen sits neatly in the middle of it.

It has plenty of non-sleeping uses too. Short-stay parking bays are frequently set at fifteen minutes, a batch of scones takes about that long, and it is a sensible warning to give children before something has to end. Meetings scheduled as "a quick fifteen" almost never keep to it without a prompt.

Selecting this preset sets an alarm exactly fifteen minutes from now. It recalculates against the current time each time it is used, so the finishing point is always accurate to the moment you started.

Common questions

Why is fifteen minutes recommended for a nap?

It is long enough to feel restorative but stops short of deep sleep, which is what tends to leave you groggy on waking.
