Going to bed for a 7:48 am alarm

Asleep by 10:33 pm — 6 full sleep cycles, about 9 hours
Asleep by 12:03 am — 5 full sleep cycles, about 7 hours
Asleep by 1:33 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 7:48 am

While you pack your bag and check the ferry timetable, set the alarm for 7:48 am before the morning rush begins. A strict bay crossing leaves little room for a slow departure, so having the alert ready now lets you focus on keys, ticket and the trip to the terminal. It also gives you 12 minutes before 8:00 am to finish those checks.

Because this alarm runs in your browser, keep the page open after setting it and leave your phone or computer awake with the sound turned up. Closing the tab or browser, or letting the device sleep, can silence the ferry reminder and leave you short of time for boarding. A quick glance at the displayed alarm time confirms that 7:48 am is active before you move on to the rest of your preparation.

Before an early departure, keep the screen dim enough for the low morning light while still making the alarm status easy to read. If the room is dark, use your device’s warm colour setting and avoid staring at a bright display while waiting. Once the time is confirmed, place the device where the alarm will be audible, then turn the screen away so its glow does not dominate the room.

Common questions

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.

Can I set more than one alarm at a time?

This page is built around a single alarm at a time. For multiple alarms, open a separate tab for each one and set a different time in each, keeping every tab open until it's rung.
