Going to bed for a 5:46 am alarm

Asleep by 8:31 pm — 6 full sleep cycles, about 9 hours
Asleep by 10:01 pm — 5 full sleep cycles, about 7 hours
Asleep by 11:31 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 5:46 am

As you finish the first batch of beans and leave the coffee shop, set the alarm for 5:46 am so the handover does not drift into the morning rush. That gives you a clear stopping point before 6:00 am: note the grind setting, leave the bench ready for the next person, and head out without repeatedly checking the clock.

While you complete the coffee shop close-down, keep this alarm page visible where practical. A browser may slow or suspend a tab that has been left in the background, so return to it after using another app and confirm the countdown is still moving. The alarm for the beans cannot sound if the page has been closed or the phone or computer has gone to sleep; use a built-in alarm as backup when leaving depends on the alert.

Moving through the house this early can wake people well before their own alarms. Put your keys, shoes and work bag near the door the night before, then keep the 5:46 am alert at a low but audible level or use vibration if your phone supports it. Silence it promptly, avoid bright overhead lights, and close the front door gently on the way to the café.

Common questions

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.

What happens once the alarm goes off?

It rings through your device's speakers on a loop until you stop it from this page. There's no separate app notification, so make sure your volume is turned up before you rely on it.

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.
