Going to bed for a 9:26 am alarm

Asleep by 12:11 am — 6 full sleep cycles, about 9 hours
Asleep by 1:41 am — 5 full sleep cycles, about 7 hours
Asleep by 3:11 am — 4 full sleep cycles, about 6 hours

A sleep cycle runs about 90 minutes, and most people take around 15 minutes to drop off. Waking at the end of a cycle feels easier than waking in the middle of one.

How to use the online alarm clock

While you wait for the scheduled office evacuation drill, set the alarm for 9:26 am and keep an eye on the time without repeatedly checking the clock. That leaves the rest of the morning’s immediate tasks clearly separated from the drill, with 10:00 am still far enough away for colleagues to return, regroup and resume work afterwards.

During the wait, the alarm page can sit behind your email or another browser page while you continue working. A background page may be slowed by the browser, so keep this page open and allow sound notifications before turning your attention elsewhere. If the browser is closed or the computer falls asleep, the alarm for the evacuation drill will not sound, which could leave you at your desk when everyone is expected to assemble.

Before leaving your desk this morning, notice whether the office feels warm despite the air conditioning. Moving from a cooled room into outdoor heat, then standing at the assembly point, can feel abrupt, so take water if workplace arrangements permit and avoid adding an unnecessary coat or heavy layer. At 9:26 am, sunshine may already be warming paved areas even on a mild British day; knowing where the shaded part of the assembly area is can make the wait more comfortable.

Common questions

What happens if my laptop goes to sleep before 9:26 am?

The tab sleeps along with it and the alarm will not sound on time, if at all. If you are relying on it, change the power settings so the machine stays awake, or keep a phone alarm running as well.

Do I need an account or an app?

Neither. Choose a time and a sound, press Start, and it runs in this browser tab. Nothing is downloaded, nothing is registered, and closing the page leaves nothing behind on the device.

Can I change the sound?

Yes, there is a short list of tones to pick from before you press Start. Softer sounds are easy to sleep through, so a firmer bell tends to be the safer choice for anything early in the morning.

Will it still be right when the clocks change?

Yes. It reads your device's local clock, so the move between GMT and BST at the end of March and October is picked up automatically, as long as the computer's date, time and time zone are set correctly.
