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

You’re handing the overnight shift back to your colleague at 3:22 am after covering their hours from another time zone. Set the alarm for the exact handover rather than relying on a tired glance at the clock. With 4:00 am approaching, there is still time to finish your notes, flag anything unresolved and make the changeover clear.

Your colleague is waiting on the other side of the handover, so check whether silent mode will suppress the alarm or leave only vibration. Set the alert volume before settling into the final stretch, then keep the phone close enough to notice it without disturbing the household. This browser alarm cannot safeguard the shift change after its active session ends or the phone goes to sleep, so use a separate system alarm as backup if missing 3:22 am would leave nobody covering.

Once the handover is ready, choose something light if you need food before 3:22 am, such as toast, fruit or a small bowl of cereal, and keep water nearby. A large meal can wait until you are properly off duty and no longer watching for messages. If you plan to sleep soon after the shift, an extra late-night coffee may also be better saved for another time.

Common questions

Will the alarm still ring if I close the browser tab?

No. The alarm only runs while this tab stays open — closing it, or closing the browser entirely, stops the countdown before it can ring. Keep the tab open in the background if you need it to go off later.

Does the alarm work if my laptop goes to sleep?

Not reliably. If the device sleeps or the screen locks, the browser tab pauses along with it, so the alarm may not fire on time or at all. Adjust your power settings if you're relying on this over a longer stretch.

Do I need to create an account or download anything?

No, there's nothing to sign up for and nothing to install. Pick a time and a sound, press Start, and it runs entirely in this browser tab.

Can I change the alarm sound?

Yes, there's a short list of tones to choose from before you press Start. Pick whichever one you're most likely to actually hear — softer sounds are easier to sleep through than a firm chime or bell.
