Going to bed for a 5:55 am alarm

Asleep by 8:40 pm — 6 full sleep cycles, about 9 hours
Asleep by 10:10 pm — 5 full sleep cycles, about 7 hours
Asleep by 11:40 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 5:55 am

Finish packing your day-charter gear and head for the marina when the 5:55 am alarm sounds. That leaves a clear departure point just before 6:00 am, when the skipper may be preparing lines, checking the forecast and getting everyone aboard. Keep your keys, hat and water together so leaving does not turn into another search through the house.

Your headphones can quietly take over the alarm audio even when you think the sound will come from the phone or computer. Before stepping away, play a quick test and confirm which speaker you actually hear, then set the volume high enough to cut through final packing. A browser alarm cannot cover your charter departure if its page is closed or the phone goes to sleep, so leave the alarm running and use a separate backup if missing the boat would disrupt the day.

Early air near an Australian marina can feel humid and noticeably cooler than it will once the sun is up. Put on a light outer layer that can be stowed after departure, and allow a moment for damp decking or a slippery jetty while carrying bags. Keeping electronics inside a zipped pouch also protects them from moisture during the walk from the car to the boat.

Common questions

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.

Is this alarm accurate across daylight saving time?

It uses your device's local clock, so as long as your computer's time and date settings are correct, it'll adjust automatically when daylight saving time starts or ends.

Can I use this on my phone instead of a laptop?

Yes, it works in a mobile browser the same way, but phones are more likely to lock the screen or sleep, which can stop the alarm from ringing. A laptop or desktop tends to be more reliable for this.
