Going to bed for a 10:47 am alarm

  • Asleep by 1:32 am — 6 full sleep cycles, about 9 hours
  • Asleep by 3:02 am — 5 full sleep cycles, about 7 hours
  • Asleep by 4:32 am — 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 10:47 am

Waking at 10:47 am means the trip to the worksite has not started yet: the keys may still be on the bench and the ute still parked outside. This alarm can mark the moment to get up, check the route after the morning traffic, and prepare to leave around 11:00 am without turning the first few minutes awake into a rush.

Because departure depends on hearing the alert, the browser needs to remain open after the alarm is set. Closing the tab or browser cancels that live session, so the worksite departure may slip by unnoticed; a sleeping phone or computer may also stay silent. Keeping the alarm page visible and the device awake makes the alert available at 10:47 am, while the displayed time provides a quick check before setting the keys down.

Before leaving for the worksite, the changing late-morning light is worth planning for near the doorway. Opening the blinds can make it easier to spot keys, paperwork and sunglasses, but direct glare across the screen may hide the alarm display. Positioning the phone away from the window beforehand keeps the time readable, and placing sunglasses beside the keys prepares for brighter roads after 11:00 am.

Common questions

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.

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.
