Going to bed for a 6:47 am alarm

Asleep by 9:32 pm — 6 full sleep cycles, about 9 hours
Asleep by 11:02 pm — 5 full sleep cycles, about 7 hours
Asleep by 12:32 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 6:47 am

Halfway through packing a school bag or finding a missing hat, you need a clear signal to stop and head out. A 6:47 am alarm marks the moment to leave for a school bus stop ten minutes away, with a little breathing room before 7:00 am. It separates the last household job from the walk outside.

Because the alarm is tied to the departure rather than the final preparation, the browser needs to remain available until it sounds. If you close its tab or the phone or laptop falls asleep, no alert will play, and the school bus may arrive while you are still at home. Check that the sound is audible before returning to breakfast, bags or shoes, and leave the screen running where it will not be dismissed accidentally.

Morning noise can change quickly around this point: a quiet kitchen may soon fill with voices, running water, doors and traffic outside. A tone that is obvious at 6:47 am can disappear into that growing background by 7:00 am, so a distinct sound placed near the area where you are getting ready is more useful than a soft alert left in another room.

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.
