Going to bed for a 7:58 am alarm

  • Asleep by 10:43 pm — 6 full sleep cycles, about 9 hours
  • Asleep by 12:13 am — 5 full sleep cycles, about 7 hours
  • Asleep by 1:43 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

An alarm for 7:58 am works well as a backup for anyone who's slept through a phone alarm before: on a desk, on a laptop, wherever the tab's open. Set it, pick a sound you'll actually hear over the kettle, and it'll go off at 7:58 am sharp.

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.

A browser alarm like this one is handy when your phone's on silent, charging in another room, or you just don't want to unlock it and get pulled into notifications. The trade-off is honesty: it only rings while this tab stays open, so it's not a replacement for your phone alarm on a trip where the laptop lid might close. On a 24-hour clock 7:58 am is written 07:58, and spoken aloud it's two minutes to eight in the morning. Written the Australian way that's 7.58 am, and typed in a hurry it's often 7:58am. Setting the alarm to 7:58 am tomorrow morning works the same way: if the time has gone for today, the count runs through to it.

Common questions

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.

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.
