Going to bed for a 4:17 am alarm

  • Asleep by 7:02 pm — 6 full sleep cycles, about 9 hours
  • Asleep by 8:32 pm — 5 full sleep cycles, about 7 hours
  • Asleep by 10:02 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.

How to use the online alarm clock

While preparing the rods, tackle and cool box for a long fishing trip to Khor Fakkan, set the alarm for 4:17 am before turning in. That gives you a clear departure cue while the UAE roads are still quiet, with 43 minutes available before 5:00 am for loading the vehicle, checking water and making sure nothing essential remains at home.

For this Khor Fakkan fishing departure, keep the alarm page in the foreground if possible, as a browser may restrict activity after its tab has been left in the background. Check that sound is allowed and set the volume before sleeping. If the browser is closed or the phone enters sleep mode, the fishing alarm may produce no sound, so use a separate device alarm when missing 4:17 am would disrupt the trip.

During a 4:17 am start, keep the room dim while gathering the last items, but avoid staring at a bright screen in the surrounding darkness. Lower the display brightness beforehand and use the phone only long enough to stop the alarm and confirm the time. Once outside, a small torch can help with the fishing gear without flooding the car or your eyes with harsh light before dawn.

Common questions

Does closing the browser tab stop the alarm from ringing?

The page must remain open for the 4:17 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 4:17 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 4:17 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 4:17 am needs to stay loaded until it rings, although you are free to switch windows, check another site, or minimise the browser.
