Going to bed for a 3:20 am alarm

Asleep by 6:05 pm — 6 full sleep cycles, about 9 hours
Asleep by 7:35 pm — 5 full sleep cycles, about 7 hours
Asleep by 9:05 pm — 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 3:20 am

You’re partway through getting ready when the 3:20 am alarm needs to pull you away to meet the Indian Pacific on a quiet overnight platform. That leaves a practical window before 4:00 am for packing the last essentials, checking the station entrance and heading out without turning the departure into a rush.

While you finish what you’re doing, keep this alarm page where the browser can continue running it. Moving the tab into the background is generally fine, so you can check a map or message while the countdown continues; returning to the page also lets you confirm that the alarm remains set. If you close the page or let your phone or laptop sleep, the alarm may not sound, which could leave the train arriving while you are still at home.

For a night departure, work backwards from when you need to leave rather than treating 3:20 am as the end of your preparation. Allow a buffer for locking up, reaching the platform and finding the right carriage area in low light. Once those tasks are covered, keep a small reserve before the next commitment later that day, especially if the Indian Pacific pickup changes how you planned the morning.

Common questions

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.

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.
