Going to bed for a 11:25 am alarm

Asleep by 2:10 am — 6 full sleep cycles, about 9 hours
Asleep by 3:40 am — 5 full sleep cycles, about 7 hours
Asleep by 5:10 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

Getting ready early for your Oxfam charity shop shift leaves time to check your bag, keys and travel plans before setting an alarm for 11:25 am. With 12:00 pm approaching, the alert can mark the point when preparations stop and it is time to leave, without making the morning feel rushed.

Your Oxfam shift depends on noticing the alarm, so check the sound setting while there is still time to correct it. Silent mode may suppress or soften browser audio on some phones, even when the alarm itself appears properly set. A quick sound test at the same volume you plan to use can reveal that problem. The alarm also cannot protect your shift if its browser page is closed or the phone falls asleep before 11:25 am, so it needs to remain active and awake until it sounds.

Late-morning daylight can make a bright screen feel harsher when you are checking the time near a window. Position the phone away from reflections and lower the display brightness enough to read 11:25 am comfortably. Once the alarm is confirmed, leaving the screen alone while you finish preparing reduces unnecessary looking and keeps your attention on getting out for the shift.

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 11:25 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.
