Going to bed for a 7:31 am alarm

Asleep by 10:16 pm — 6 full sleep cycles, about 9 hours
Asleep by 11:46 pm — 5 full sleep cycles, about 7 hours
Asleep by 1:16 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 7:31 am

Waiting for 7:31 am before your foreshore run lets you keep an eye on the clock while finishing a few quiet preparations. Shoes, keys and water can be ready without heading into the rising heat too soon. The alarm marks the moment to leave, while 8:00 am provides a useful checkpoint for how far along the waterfront you expect to be.

While you wait to start the run, keep the alarm page available and check that your sound is audible. A browser page moved into the background may receive less attention from the phone, so the display can update late even when the alarm was set correctly. A closed browser or sleeping phone means the alarm cannot sound, so your run could begin later than planned; use the phone’s built-in alarm as a backup when timing matters.

Leaving at 7:31 am can still put you among commuters, school traffic and cyclists joining shared paths. Allow for the walk or drive to the waterfront rather than treating the alarm time as the moment your run begins. If parking is part of the trip, choose a familiar access point and include those extra minutes when deciding where you should be by 8:00 am.

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.
