Going to bed for a 3:22 am alarm

Asleep by 6:07 pm — 6 full sleep cycles, about 9 hours
Asleep by 7:37 pm — 5 full sleep cycles, about 7 hours
Asleep by 9:07 pm — 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 3:22 am

As you finish getting ready and leave for your NHS night shift, set the browser alarm for 3:22 am so the final part of your routine has a clear end. That still leaves 38 minutes before 4:00 am, enough time to reach the ward, change, or collect a handover without treating the round hour as your real deadline.

Before relying on the alert, give it a trial while you are still preparing to go: start a short test alarm, confirm that you hear the sound, and then restore 3:22 am. Keep the volume at a level that will cut through whatever you are doing. For this NHS shift, the alarm will not sound if its browser tab has been closed or the device has gone to sleep, so use a separate backup if missing the alert would make you late.

Because you are heading out long before sunrise, arrange the room lighting before the alarm is due rather than searching for switches at 3:22 am. Leave a low lamp on near your clothes and bag, but keep the main light off while you wait. Once the alarm sounds, switch on a brighter light before checking that you have your pass, keys, and anything needed for the shift.

Common questions

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 3:22 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.
