Three questions the wake pages do not answer. The bedtime alarm runs on the same two numbers as the wake pages — the length of a cycle and the minutes it takes to drop off; the screen cutoff is one subtraction, and the world clock reads the time-zone rules. Shift work has a section of its own, with the rota planner.
Bedtime alarm
The alarm nobody sets. Give it the hour you have to be up and it gives back one time: when to be told to go to bed. It runs the other way too.
Screen cutoff
You choose the gap between the last screen and the light going out. This turns it into a time on the clock, which is the part that is irritating to do in your head.
World clock
A map with the hour lines drawn on it and the local time in twelve cities, plus the January and July offset of every city the site knows.
Where each one starts
Two of the three open on a worked example rather than an empty form, and every number in the example can be changed; the world clock opens on the time where you are. These are the starting values, and how far each one moves.
| Tool | Starts at | Moves |
|---|---|---|
| Bedtime alarm | up at 6:00 am, with the bedtime alarm 30m before getting into bed | 0m to 1h 30m, in steps of 5m |
| Screen cutoff | in bed at 10:15 pm, with a gap of 1h | 15m to 4h, in steps of 15m |
| World clock | your device's own time zone, and 12 cities on the board | all 89 cities, grouped by offset |
Under the alarm sit the same assumptions as every other page: a cycle of 90 minutes, which moves from 60 to 120 in steps of 5, and 15 minutes to drop off, which moves from 0 to 45. Set them on any page that counts cycles and they follow you to the alarm and to the shift planner.
What none of them do
None of them have a view. They count minutes, they count cycles, and where a number will not fit they say so — that is the whole of the judgement on offer. Nothing here has measured anybody, so nothing here makes a claim about what any of it does to a body. If you want to know what the site is and is not in a position to say, that is set out on its own page.
