Going to bed for a 8:25 am alarm

  • Asleep by 11:10 pm — 6 full sleep cycles, about 9 hours
  • Asleep by 12:40 am — 5 full sleep cycles, about 7 hours
  • Asleep by 2:10 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.

How to use the online alarm clock

If mornings mean footy training drop-offs, an early meeting, or getting the kids to school on time, 8:25 am is worth locking in properly. This rings straight from your browser at 8:25 am, and keeps ringing until you tell it to stop. No phone required nearby.

Set your preferred sound, press Start, then leave the tab where it is. Everything happens inside the browser — no background app, no notification pushed from a server — so an open tab is what actually makes the alarm ring at the right time.

The advantage of a browser alarm is volume and reliability at a desk: laptop speakers are often louder and easier to hear across a room than a phone left in a bag. The catch is that it depends entirely on the tab staying open; if the browser closes or the laptop sleeps, the alarm won't fire. On a 24-hour clock 8:25 am is written 08:25, and spoken aloud it's twenty-five past eight in the morning. Timetables and rosters may show it as 08:25, and handwritten notes as 8.25 am. Setting the alarm to 8:25 am tomorrow morning works the same way: if the time has gone for today, the count runs through to it.

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.
