Going to bed for a 3:09 am alarm

  • Asleep by 5:54 pm — 6 full sleep cycles, about 9 hours
  • Asleep by 7:24 pm — 5 full sleep cycles, about 7 hours
  • Asleep by 8:54 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 3:09 am

Hand the risen dough to the incoming baker with a 3:09 am alarm marking the changeover. That gives them a clear cue to check the batch, shape it or move it towards the oven according to the bakery’s schedule. Note what has already been done before you finish your shift, especially if another batch is due before 4:00 am.

Match the alarm sound to what will be happening around the dough. A softer tone may suit a quiet bakery where the next baker is working nearby, while a persistent sound makes more sense over mixers, exhaust fans or tray noise. Set the volume high enough to be distinct without startling everyone on the overnight shift. This browser alarm must remain open with the phone or computer awake; otherwise the dough handover could be missed because no sound will play.

Leave the incoming baker enough light to read your batch notes without flooding the whole work area at 3:09 am. Switch on a bench light before stepping away, and angle it towards the timer, labels and prepared trays rather than towards anyone’s eyes. Keeping the route between the proving area and oven gently lit also makes the changeover easier while the street outside is still dark.

Common questions

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.

Is there a cost to use this?

No, it's free, with no sign-up and no limit on how many times you set it. It just needs the tab left open until the time you've chosen arrives.
