Going to bed for a 4:46 am alarm

Asleep by 7:31 pm — 6 full sleep cycles, about 9 hours
Asleep by 9:01 pm — 5 full sleep cycles, about 7 hours
Asleep by 10:31 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 4:46 am

Handing the boat over to the next fisher at 4:46 am means leaving clear notes on the weather, fuel and where the fish were biting before dawn. Set the alarm for this exact time so the changeover does not drift towards 5:00 am and shorten the next person’s quiet run on the water.

A fishing handover may need a gentle sound if someone else is sleeping nearby, while a more persistent tone suits a noisy cabin or gear shed. Choose a tone that fits the setting, set the volume high enough to hear over preparations, and confirm that the alarm is armed. Keep the browser alarm active and the phone awake, because otherwise the boat handover could be missed without any sound.

Before leaving for the ramp in the dark, allow for the full drive rather than assuming empty roads guarantee a quick trip. At this hour, wildlife, roadworks and reduced lighting can slow a country route, while access gates or trailer parking may add extra minutes near the water. Check the route before settling down, place keys and fishing gear together, and leave enough time to arrive calmly before first light.

Common questions

Why use a browser alarm instead of my phone's built-in one?

Mainly for reliability against silent mode, do-not-disturb, or a phone left charging out of earshot. It's a useful backup or a desk-based alternative, though it depends on this tab staying open rather than running in the background of your phone.

Is there a cost to use this?

No, it's free, with no sign-up and no limit on how many times you set it. It just needs the tab left open until the time you've chosen arrives.

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.
