Going to bed for a 9:20 am alarm

Asleep by 12:05 am — 6 full sleep cycles, about 9 hours
Asleep by 1:35 am — 5 full sleep cycles, about 7 hours
Asleep by 3:05 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.

Online alarm clock for 9:20 am

Waking at 9:20 am gives you a clear starting point before your shift at the Oxfam charity shop. You have not begun getting ready yet, so the alarm can mark the moment to sit up, check when you need to leave and move into your morning routine. With 10:00 am approaching, there is time to wash, dress and gather what you need without treating every minute as a rush.

Your Oxfam shift may begin smoothly only if the 9:20 am alarm is actually audible, and headphones can quietly take over the sound without you noticing. Check where your browser audio is playing, then set a sensible volume and run a brief test while the headphones are connected. If the browser page is closed or your phone falls asleep, the alarm may not sound and you could miss the start of your shift, so keep the page open and the phone awake until it rings.

As the shop shift shapes the rest of your morning, any sleep left after 9:20 am should be treated deliberately rather than drifting back under the duvet. If you intend to get up now, placing the phone beyond easy reach can prevent an automatic snooze. If your schedule allows more sleep, set a separate later alarm that still leaves a realistic margin for breakfast, dressing and the journey to Oxfam.

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.
