Going to bed for a 5:58 am alarm

  • Asleep by 8:43 pm — 6 full sleep cycles, about 9 hours
  • Asleep by 10:13 pm — 5 full sleep cycles, about 7 hours
  • Asleep by 11:43 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.

How to use the online alarm clock

Handing the changing-room warm-up to the next caretaker at 5:58 am means leaving a clear cue, not a vague instruction. Set the alarm for 6:00 am so they know when to check the controls before the school match, then tell them what has already been switched on and which rooms still need attention. Those two minutes are enough for a brief handover without losing track of the exact check time.

While the caretaker moves between corridors, this alarm page may sit behind another browser tab and continue counting towards the set time. Bring it back to the front before stepping away, keep the sound level audible, and avoid relying on a screen that may soon lock. If the browser is closed or the computer goes to sleep, the changing-room alarm will not sound, so the handover needs a separate backup whenever nobody will remain near the open page.

For an early school fixture, the person taking over should check how the changing room actually feels rather than assuming every area needs more heat. At 6:00 am, a cool outdoor temperature can hide stuffiness indoors, especially after heating has run for a while. If the building has air conditioning, confirm it is not cooling against the heating; use the existing controls steadily and note any adjustment for the later staff.

Common questions

Does the alarm still work if I close the tab?

No. Everything runs inside this page, so closing the tab — or quitting the browser altogether — ends the countdown there and then. Leaving it open in the background is all it asks, and switching to another tab makes no difference.

What happens if my laptop goes to sleep before 5:58 am?

The tab sleeps along with it and the alarm will not sound on time, if at all. If you are relying on it, change the power settings so the machine stays awake, or keep a phone alarm running as well.

Do I need an account or an app?

Neither. Choose a time and a sound, press Start, and it runs in this browser tab. Nothing is downloaded, nothing is registered, and closing the page leaves nothing behind on the device.

Can I change the sound?

Yes, there is a short list of tones to pick from before you press Start. Softer sounds are easy to sleep through, so a firmer bell tends to be the safer choice for anything early in the morning.
