Going to bed for a 9:47 am alarm

Asleep by 12:32 am — 6 full sleep cycles, about 9 hours
Asleep by 2:02 am — 5 full sleep cycles, about 7 hours
Asleep by 3:32 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 9:47 am

While getting ready for a timed doctor’s appointment, set the alarm for 9:47 am before packing your Medicare card, referral and anything the clinic requested. That leaves a clear prompt ahead of 10:00 am, whether you need to leave home, walk from a nearby café or check in at reception. Preparing it now avoids relying on a rushed glance at the clock later.

As appointment details take over the screen, this alarm page may sit in the background. Keep the browser session open and check that sound is permitted; a background page can remain active, but phone settings and power-saving behaviour may reduce its reliability. If the browser is closed or the phone falls asleep, the alarm may not sound, so use another reminder as backup for the doctor’s appointment.

By 9:47 am, weekday noise around Australian clinics can be shifting from the school-run rush to steadier traffic, deliveries and conversations near reception. Choose a place where the alarm can be heard above that changing background without disturbing a waiting room. If you are still outside, keep the phone close rather than buried in a bag; indoors, use a moderate volume and vibration so the reminder remains noticeable amid voices and opening doors.

Common questions

Do I need to create an account or download anything?

No, there's nothing to sign up for and nothing to install. Pick a time and a sound, press Start, and it runs entirely in this browser tab.

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.
