How to use the online alarm clock

Fifteen minutes is the length of a useful nap — long enough to be restorative, short enough to stop well before the deep sleep that leaves you groggy afterwards. It is also close to the running time between several of the busier metro stations, which makes it a handy unit for anyone judging whether a journey is worth starting.

Around the house it covers rice resting off the heat with the lid on, a short set of laundry, and the interval most delivery services quote once a rider has picked something up. In an office it is the standard length of a stand-up meeting that is meant to stay standing.

The alarm is set fifteen minutes from the moment you open the page. As with everything here it needs the tab to stay open and the device awake, which for a nap on a phone is exactly the situation where that caveat bites hardest.
