Going to bed for a 9:36 am alarm

Asleep by 12:21 am — 6 full sleep cycles, about 9 hours
Asleep by 1:51 am — 5 full sleep cycles, about 7 hours
Asleep by 3:21 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 9:36 am

Before handing the interstate drive to someone else at 9:36 am, confirm which local time they will follow after reaching the neighbouring state. The alarm can mark the moment when your part ends, while the 24 minutes before 10:00 am leave room to pass over the keys, route notes and the agreed arrival time without rushing the changeover.

During the handover, this page may slip behind maps or messages. A background page can be slowed by the browser, so leave its sound enabled and check that the alarm remains visible before you step away. Your departure for the neighbouring state gets no alert if this page has stopped running or the screen’s sleep mode suspends it; use the vehicle clock or another independent alarm as a backup.

Because the change happens mid-morning, other people in the house may still be working, studying or finishing breakfast when the 9:36 am sound plays. Set a volume that can be heard from where the keys and bags are waiting, but place the phone close to you rather than across a shared room. A brief spoken reminder about the different state time can also prevent someone at home from expecting an update according to the wrong clock.

Common questions

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.

Why use a browser alarm instead of my phone's built-in one?

Mainly for reliability against silent mode, do-not-disturb, or a phone left charging out of earshot. It's a useful backup or a desk-based alternative, though it depends on this tab staying open rather than running in the background of your phone.

Is there a cost to use this?

No, it's free, with no sign-up and no limit on how many times you set it. It just needs the tab left open until the time you've chosen arrives.
