Going to bed for a 7:24 am alarm

Asleep by 10:09 pm — 6 full sleep cycles, about 9 hours
Asleep by 11:39 pm — 5 full sleep cycles, about 7 hours
Asleep by 1:09 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 7:24 am

Halfway through another early lap with the dog, a 7:24 am alarm is a cue to turn back rather than keep wandering while the footpath is still comfortable. That leaves enough time to reach home, refill the water bowl and settle the dog before 8:00 am, when the asphalt may already be taking on more heat.

Because the sound needs to cut through street noise and the distraction of handling a lead, check the phone’s silent setting before relying on this alarm. Set the volume at a level you will notice outdoors, then keep the alarm page active while you are out. The dog walk may continue past 7:24 am if that page stops running or the phone falls asleep, so a separate built-in alarm is a sensible backup when the return time matters.

Coming home from an early dog walk can still leave a small window for more sleep. Keeping the room dim, placing water and the lead near the door beforehand, and leaving breakfast preparation until later can make the return less disruptive. If you plan to lie down again after 7:24 am, set a second alarm for the actual start of the day and allow a few minutes to settle the dog first.

Common questions

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.

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.
