Going to bed for a 8:45 am alarm

  • Asleep by 11:30 pm — 6 full sleep cycles, about 9 hours
  • Asleep by 1:00 am — 5 full sleep cycles, about 7 hours
  • Asleep by 2:30 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.

How to use the online alarm clock

Set 8:45 am for the dog's walk before Dubai pavements become much hotter. For the dog’s comfort, the next round hour is 9:00 am, only 15 minutes away, so quarter to nine is a clear last call rather than an invitation to delay. Have the lead and waste bags ready, and use the alert to step outside for a short, purposeful route.

Choose a tone you will notice over household sounds, test the volume and press Start. Keep the browser tab open until it rings, even if you use another app while waiting. The alarm cannot play from a closed tab, and it will also remain silent if the device is asleep. Leave the device awake, connect it to power and check that the sound is not routed to wireless headphones.

Test the pavement with the back of your hand and choose shaded ground wherever possible. Carry water for the dog, avoid strenuous running and watch for signs that the animal wants to turn back. If the surface or air already feels too hot, make this a brief toilet break and save a longer walk for a cooler period.

Common questions

Does closing the browser tab stop the alarm from ringing?

The page must remain open for the 8:45 am alarm to sound. Switching tabs, minimising the window, or using another application will not end it, but closing the alarm tab or quitting the browser will.

Can the alarm ring if this tab is no longer open?

Think of the browser tab as the alarm's running space: once that tab is closed, the alarm scheduled for 8:45 am can no longer continue. It does not need to stay visible, so you may minimise the window or browse elsewhere.

Will my alarm work once I have closed the tab?

No, closing the page stops the alarm rather than leaving it active in the background. For an alert at 8:45 am, keep that particular tab open; it can sit behind other tabs or inside a minimised browser window.

Does the tab need to stay open for the alarm?

Your device will not take over the alarm after the webpage closes. The tab containing the alarm for 8:45 am needs to stay loaded until it rings, although you are free to switch windows, check another site, or minimise the browser.
