Going to bed for a 9:10 am alarm

Asleep by 11:55 pm — 6 full sleep cycles, about 9 hours
Asleep by 1:25 am — 5 full sleep cycles, about 7 hours
Asleep by 2:55 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

Handing your current task to someone else at 9:10 am gives you a clear moment to switch roles and get ready to leave for your Oxfam charity shop shift. With 10:00 am approaching, the alarm separates the handover from the journey, so keys, lunch and anything needed at the shop are less likely to remain behind.

Your handover may continue while this page sits behind another tab, and the alarm should remain set while you check a rota or message a colleague. The browser may give a background page fewer resources, however, so confirm that the alarm still appears active and that sound is allowed. If the page is closed, or your phone or laptop goes to sleep, no alarm can sound and the Oxfam shift may begin without you.

Leaving for a morning shift often means looking between a bright window and a dim screen. At 9:10 am, matching the display brightness to the room can make the alarm controls easier to read without a stark glare. Positioning the screen away from direct sunlight also helps you check the set time quickly before finishing the handover and heading out.

Common questions

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.

What happens if my laptop goes to sleep before 9:10 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.
