Going to bed for a 6:34 am alarm

Asleep by 9:19 pm — 6 full sleep cycles, about 9 hours
Asleep by 10:49 pm — 5 full sleep cycles, about 7 hours
Asleep by 12:19 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 6:34 am

Pause halfway through hitching the trailer and set the alarm for 6:34 am, so packing straps or checking the coupling does not carry you past the moment you meant to leave. That gives you a clear break from the job while the morning is still cool, with 7:00 am as a useful fallback point for being on the road before the heat builds.

While you finish preparing the trailer, keep the alarm page visible and turn up the alert volume. Silent mode may suppress the sound even though the alarm appears to be running, so check the setting before putting the phone down. A browser alarm also cannot call you back to the trailer if its page has been closed or the phone has gone to sleep; use a built-in alarm as backup if missing 6:34 am would delay departure.

With the trailer nearly ready in the dim early-morning light, lower the screen brightness before making the final checks. Use a warm display setting if your phone provides one, and place it where the alarm remains visible without shining directly into your eyes. A brief glance at a softened screen is more practical than repeatedly unlocking a bright phone while moving between the tow vehicle, coupling and straps.

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.
