Going to bed for a 7:17 am alarm

Asleep by 10:02 pm — 6 full sleep cycles, about 9 hours
Asleep by 11:32 pm — 5 full sleep cycles, about 7 hours
Asleep by 1:02 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 7:17 am

As you hand the school bus run over to someone else at 7:17 am, the key detail is that the stop is a ten-minute walk away. An alarm for this time gives the next person a clear cue to leave, rather than relying on a hurried message or a glance at the clock. There is still room before 8:00 am for the pickup and the rest of the morning routine.

For this handover, the alarm page needs to remain ready while the phone is set aside. The selected time should be checked before the other person takes responsibility, with the sound turned up enough to be noticed. Closing the page or allowing the phone to sleep may prevent the browser alarm from sounding, which could leave the school bus pickup without its planned cue. A separate phone alarm is sensible when missing that cue would disrupt the trip.

Early light can make a bright screen feel unnecessarily harsh while bags, lunch boxes and keys are being gathered. Keeping the display dim at 7:17 am makes the time easier to check without flooding the room with light. Once the alarm is prepared, placing the phone face down but within hearing range reduces repeated screen checks while the household gets ready for the stop.

Common questions

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.

What happens once the alarm goes off?

It rings through your device's speakers on a loop until you stop it from this page. There's no separate app notification, so make sure your volume is turned up before you rely on it.
