Going to bed for a 8:20 am alarm

  • Asleep by 11:05 pm — 6 full sleep cycles, about 9 hours
  • Asleep by 12:35 am — 5 full sleep cycles, about 7 hours
  • Asleep by 2:05 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 8:20 am

Waiting for the 8:20 am alarm before the rugby team’s training session can leave you watching every minute instead of finishing your breakfast or packing your school bag. Set this page for 8:20 am and keep the sound within hearing distance, so you can focus on getting your boots, mouthguard and water bottle together. The alarm leaves another 40 minutes before 9:00 am, which may be useful for the session, the trip home or the start of school.

Before relying on the alarm for rugby training, run a quick sound check while there is still time to fix anything unexpected. Choose a nearby test time, confirm that the tone plays clearly, then reset it for 8:20 am and check the displayed time. If the browser is no longer running when training time arrives, the alarm cannot sound, so use a separate backup if missing the session would disrupt the team.

An early rugby start can affect everyone who is still asleep, especially when bags, doors and breakfast dishes add more noise than the alarm itself. Keep the phone close and select a level that you can hear without carrying through the house. Pack your kit the night before, place keys and shoes near the exit, and silence the alarm promptly at 8:20 am; that keeps the household quieter while still giving you a clear signal to leave.

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.
