Going to bed for a 4:55 am alarm

Asleep by 7:40 pm — 6 full sleep cycles, about 9 hours
Asleep by 9:10 pm — 5 full sleep cycles, about 7 hours
Asleep by 10:40 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.

Online alarm clock for 4:55 am

While you prepare for an early check of the fruit orchard’s flying-fox protection nets, set the alarm for 4:55 am before gathering your torch, gloves and repair ties. That gives you a clear cue to finish packing and be ready to head between the rows by 5:00 am, rather than watching the clock while you organise your gear.

Because the alarm is needed before dawn, consider whether your phone normally locks or enters a sleep mode while you are getting dressed. Keep this browser page open, leave the phone awake and make sure its volume is audible. If the page is closed or the phone goes to sleep first, the alarm may not sound, which could delay your orchard inspection. A nearby power connection can also prevent a low battery from ending the session before 4:55 am.

Plan the orchard round with enough breathing room before your next job later that morning. At this hour, darkness can slow movement around posts, loose netting and uneven ground, so allow time to check the first section carefully instead of treating 5:00 am as the finish time. Put your torch where you can reach it immediately, and decide which row you will inspect first while you are still indoors.

Common questions

Will the alarm still ring if I close the browser tab?

No. The alarm only runs while this tab stays open — closing it, or closing the browser entirely, stops the countdown before it can ring. Keep the tab open in the background if you need it to go off later.

Does the alarm work if my laptop goes to sleep?

Not reliably. If the device sleeps or the screen locks, the browser tab pauses along with it, so the alarm may not fire on time or at all. Adjust your power settings if you're relying on this over a longer stretch.

Do I need to create an account or download anything?

No, there's nothing to sign up for and nothing to install. Pick a time and a sound, press Start, and it runs entirely in this browser tab.

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.
