Going to bed for a 9:58 am alarm

Asleep by 12:43 am — 6 full sleep cycles, about 9 hours
Asleep by 2:13 am — 5 full sleep cycles, about 7 hours
Asleep by 3:43 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 9:58 am

You’ve only just woken, and the interstate bus you need to meet at the roadside station is already shaping the morning. An alarm for 9:58 am gives you a clear moment to get moving before 10:00 am, without relying on a sleepy glance at the clock. Allow enough time for dressing, collecting your keys and checking the bus arrival details.

With the roadside pickup depending on you hearing the alert, check where your phone is sending its audio after setting the alarm. Headphones can remain connected in a pocket or beside the bed, quietly taking the sound that you expect from the speaker. A quick test at your current volume can reveal that routing. The bus reminder may stay silent if the browser page is closed or the phone goes to sleep, so the alarm needs the page open and the phone awake until 9:58 am.

Before leaving for the station in the late morning, check how the outdoor air feels rather than judging it through the window. Australian humidity can make a short roadside wait feel stuffier than expected, while dry air may call for water on the trip. Choosing a shaded waiting spot and carrying a light layer gives you options if the air changes between home and the bus stop.

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.
