Going to bed for a 9:18 am alarm

Asleep by 12:03 am — 6 full sleep cycles, about 9 hours
Asleep by 1:33 am — 5 full sleep cycles, about 7 hours
Asleep by 3:03 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 9:18 am

You’re wrapping up what you’re doing and heading out to take your child’s uniform to the school swimming carnival. Set the alarm for 9:18 am so leaving does not slip behind one last job or conversation. It gives you a clear departure cue while still leaving the rest of the morning before 10:00 am.

Your child’s swimming uniform needs to arrive with you, so keep the browser alarm where you can see it while you finish packing. Check that the sound is audible, leave the page running, and keep your phone or computer awake. If the browser is closed or the device sleeps first, the alarm may not sound, which could leave the uniform waiting at home when you should already be travelling.

The trip to a school carnival can take longer once morning traffic builds around drop-off zones, shopping strips and busy intersections. At 9:18 am, allow for the actual drive, parking, and the walk from the car to the pool entrance rather than treating arrival at the car park as the finish. Put the uniform somewhere visible before leaving, and use the alarm as the point when you stop other tasks and get on the road.

Common questions

Can I change the alarm sound?

Yes, there's a short list of tones to choose from before you press Start. Pick whichever one you're most likely to actually hear — softer sounds are easier to sleep through than a firm chime or bell.

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.
