Going to bed for a 4:25 am alarm

  • Asleep by 7:10 pm — 6 full sleep cycles, about 9 hours
  • Asleep by 8:40 pm — 5 full sleep cycles, about 7 hours
  • Asleep by 10:10 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

Before your night shift at Jebel Ali Port finishes, set the alarm for 4:25 am so the final checks do not drift into the handover. Preparing it now leaves a clear marker before 5:00 am, whether you are completing paperwork, checking equipment, or getting ready to leave the port.

As the shift winds down, keep this alarm page open and confirm that your phone volume is high enough to hear over nearby machinery. If the browser or its tab is closed, or the phone falls asleep, the alarm may not sound for the end of your night shift. Keep the screen awake and the page visible; for a critical handover, also set the phone’s built-in alarm as a backup.

Leaving an air-conditioned work area at 4:25 am can make the outdoor warmth feel sharper, even before sunrise. Keep a light layer within reach for the final indoor tasks, then remove it before walking to transport or crossing an exposed section of the port. A bottle filled before the handover also avoids an extra stop as the shift ends and the early Dubai heat begins to build.

Common questions

If I close the tab, will the alarm still go off?

Closing the tab cancels the alarm because the timer for 4:25 am is handled by that page, not by your device as a separate system alarm. Leaving the page open in the background is fine, even if another tab is on screen.

Does closing the browser tab stop the alarm from ringing?

The page must remain open for the 4:25 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 4:25 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 4:25 am, keep that particular tab open; it can sit behind other tabs or inside a minimised browser window.
