Going to bed for a 5:45 am alarm

Asleep by 8:30 pm — 6 full sleep cycles, about 9 hours
Asleep by 10:00 pm — 5 full sleep cycles, about 7 hours
Asleep by 11:30 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 5:45 am

While you watch the clock for the scheduled river rowing session, a 5:45 am alarm can mark the moment to get the crew moving. It leaves a short, useful window before 6:00 am for launching the shell, checking the oars and settling into position without treating the round hour as the actual start.

Your 5:45 am alert may quietly play through connected headphones, so check the sound output before waiting beside the river. Set a distinct tone, raise the volume enough to hear it over water and early traffic, then keep the alarm running in the foreground. The alarm cannot reliably signal rowing training if the browser is dismissed or the computer falls asleep, so use a separate alarm when missing the session would leave the crew waiting.

Once the early session ends, allow a clear buffer before the next commitment that day. Work backwards from when you must leave the river, including time to carry the shell, stow wet gear, change clothes and cross morning traffic. A second reminder for pack-up time can protect that margin, especially when a calm 5:45 am start makes the rest of the morning feel less hurried than it really is.

Common questions

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.

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.
