Going to bed for a 6:17 am alarm

Asleep by 9:02 pm — 6 full sleep cycles, about 9 hours
Asleep by 10:32 pm — 5 full sleep cycles, about 7 hours
Asleep by 12:02 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 the surgery is still quiet, you can use a 6:17 am alarm as an advance cue to prepare the consulting room before the morning GP appointments begin. It leaves a clear window for switching on equipment, setting out routine supplies and checking that the room is ready ahead of 7:00 am, without turning the early start into a rush.

For this particular job, the alarm tone should match how much attention the preparation needs. A soft sound may suit a quiet surgery when you are already nearby, while a more persistent tone is useful if you might be elsewhere completing another opening task. Test the volume briefly, then leave the alarm page running. The alarm cannot prompt you to prepare the consulting room if the browser session ends or the computer goes to sleep.

Before daylight has properly filled the building, keep the screen from becoming the brightest object in the room. Lower its brightness to a readable level, use a warmer display setting if available, and place it where you can glance at 6:17 am without staring into glare. Once the alarm is set, turning the screen away from your direct line of sight can keep the workspace calm while still leaving the time easy to check.

Common questions

What happens if my laptop goes to sleep before 6:17 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.
