Going to bed for a 5:36 am alarm

Asleep by 8:21 pm — 6 full sleep cycles, about 9 hours
Asleep by 9:51 pm — 5 full sleep cycles, about 7 hours
Asleep by 11:21 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 5:36 am

While you watch the clock for your 5:36 am alarm, your board, wettie and work gear can stay ready by the door. The alert marks the moment to head out for a morning surf before your shift, with 24 minutes remaining until 6:00 am for the last checks and trip to the beach.

Your pre-shift surf depends on leaving at the planned moment, so test the alarm sound now rather than discovering a muted setting at 5:36 am. Set a brief trial alert, confirm that its volume is distinct from your other phone sounds, then restore the intended time. Because this browser alarm works only while the browser remains active, relying on it alone could leave your morning surf starting late if the system goes inactive; use a separate backup when timing is tight.

As you wait to leave in the early morning, listen for how the surroundings change around 5:36 am. A quiet household can make a moderate alarm easy to hear, while surf, wind, traffic or someone preparing for work may mask it as dawn approaches. Keep the alarm close enough to be audible over that changing background, but away from anything you might cover with a towel or wetsuit.

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.
