Going to bed for a 10:26 am alarm

Asleep by 1:11 am — 6 full sleep cycles, about 9 hours
Asleep by 2:41 am — 5 full sleep cycles, about 7 hours
Asleep by 4:11 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

Breaking away from a task at 10:26 am can give you the prompt needed to leave for a vaccination at your local pharmacy. Set this alarm for the point when you must stop what you are doing, gather any appointment details and head out. With 11:00 am approaching, the alert separates your current activity from the trip rather than leaving you to keep checking the clock.

Your 10:26 am alarm may remain visible when its browser tab moves into the background, but the browser can restrict activity or sound when that page is no longer active. Keep the alarm page available, check that sound is permitted and leave the phone awake enough to run it. If the page is closed or the phone falls asleep, the alarm cannot sound, which could leave your pharmacy vaccination without its planned reminder.

Returning from the pharmacy late in the morning may still leave time for sleep, especially after a night shift or an unusually early start. Before resting, use a separate later alarm for the time you genuinely need to be up, and place the phone where its sound will carry. Avoid treating the 10:26 am alert as that waking alarm: it marks the moment to leave, while any sleep remaining afterwards needs its own clear endpoint.

Common questions

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.

Can I use this on a phone?

It works in a mobile browser, but phones lock the screen and suspend background tabs far more readily than a laptop does, which can stop the alarm sounding. For anything important, a desktop or a plugged-in laptop is the steadier option.

Does the alarm still work if I close the tab?

No. Everything runs inside this page, so closing the tab — or quitting the browser altogether — ends the countdown there and then. Leaving it open in the background is all it asks, and switching to another tab makes no difference.
