Going to bed for a 10:05 am alarm

  • Asleep by 12:50 am — 6 full sleep cycles, about 9 hours
  • Asleep by 2:20 am — 5 full sleep cycles, about 7 hours
  • Asleep by 3:50 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 10:05 am

You’re only just waking at 10:05 am, with an interstate drive still ahead and no part of the trip under way. An alarm at this time creates a clear starting point for checking the local time across the border, getting dressed and gathering what belongs in the car. By 11:00 am, those first preparations can be finished without treating both states as though their clocks necessarily match.

For a departure that depends on the right local time, the signal is worth hearing before relying on it. A brief test now confirms that the volume is audible and the chosen sound is recognisable from another room. The state crossing also needs another safeguard: if the browser session ends or the phone falls asleep, this alarm will not sound, which could leave the trip starting later than intended. A built-in phone alarm can cover that gap.

Since the drive begins late in the morning, a simple breakfast and some water can fit comfortably before leaving. Something easy to handle at home avoids juggling food while loading the car, while a heavier meal can wait until a planned stop. Filling a water bottle now also makes it less tempting to delay departure for a drink just as the morning is moving towards midday.

Common questions

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.

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.
