Going to bed for a 9:19 am alarm

Asleep by 12:04 am — 6 full sleep cycles, about 9 hours
Asleep by 1:34 am — 5 full sleep cycles, about 7 hours
Asleep by 3:04 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 9:19 am

You’re handing the Australia Post letterbox check to someone else when the 9:19 am alarm sounds, so leave them clear instructions about what to bring inside and where to put it. The alert gives the handover a definite moment rather than letting the job drift towards 10:00 am, when the morning may already have moved on to other tasks.

Because this reminder is tied to the letterbox check, keep the browser open while you wait and make sure the computer or phone stays awake. If you close the page or the browser, or let the device sleep, the alarm cannot sound, which could leave the Australia Post delivery sitting outside after the handover. Set the volume before stepping away, then use the visible countdown to confirm that 9:19 am is still the active alarm time.

A letterbox check at this point in the morning may overlap with breakfast, remote work or someone getting ready to leave the house. Choose an alert volume that the person taking over can hear without startling everyone nearby, and tell other household members what it signals. If the letterbox is near a bedroom window or a barking dog, ask for a quiet check and have the delivery brought inside promptly.

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.
