Going to bed for a 3:46 am alarm

  • Asleep by 6:31 pm — 6 full sleep cycles, about 9 hours
  • Asleep by 8:01 pm — 5 full sleep cycles, about 7 hours
  • Asleep by 9:31 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 3:46 am

As you hand the catch-unloading shift to someone else at 3:46 am, confirm who is taking the next crate and what remains on the boat. The alarm marks a clean changeover rather than the start of another job. With 4:00 am close, there is still time to pass on the wharf position, tally and any gear that needs attention before the market opens.

A working wharf can swallow a quiet alert under engines, pumps, gulls and moving crates, so set the alarm volume against the noise you actually expect. Play the selected signal once before relying on it, and place the phone where the handover crew can hear it without putting it in the work path. If the browser page is closed or the device falls asleep, no alarm will sound, which could leave the catch waiting on the wharf when the market opens.

During a 3:46 am changeover, the air outside may still feel warm even after hours in an air-conditioned cab or office. Keeping a light outer layer near the exit makes the sudden temperature change less distracting while you explain the remaining unload. Put the phone away from the conditioner’s airflow and hum, but within easy reach, so the signal stays audible and the screen is not forgotten inside.

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.
