How to use the online alarm clock

Waiting for the moment to leave for your passport office appointment can make every glance at the clock feel slightly premature. An alarm set for 2:43 pm gives you a clear cue, while 3:00 pm remains a useful reference point for checking your papers, putting away your phone and being ready when your allotted time approaches.

Your passport office visit may call for a gentle tone if you are already in the waiting area, but a more insistent sound can help if you are still occupied nearby. Choose an alarm that suits that setting, then set the volume high enough to notice without startling everyone around you. Keep the browser alarm active and the computer or phone awake; otherwise, it will not sound and you could miss your appointment.

Before setting off around 2:43 pm, check how the midday air actually feels outside rather than judging it through the window. High humidity can make a short walk or queue feel stuffier, while a breeze may make the same temperature seem quite different. A light layer that is easy to carry and a few minutes in the shade can make the wait until 3:00 pm more comfortable.

Common questions

Can I use this on a phone?

It works in a mobile browser, but phones lock the screen and suspend background tabs far more readily than a laptop does, which can stop the alarm sounding. For anything important, a desktop or a plugged-in laptop is the steadier option.

Does the alarm still work if I close the tab?

No. Everything runs inside this page, so closing the tab — or quitting the browser altogether — ends the countdown there and then. Leaving it open in the background is all it asks, and switching to another tab makes no difference.

What happens if my laptop goes to sleep before 2:43 pm?

The tab sleeps along with it and the alarm will not sound on time, if at all. If you are relying on it, change the power settings so the machine stays awake, or keep a phone alarm running as well.

Do I need an account or an app?

Neither. Choose a time and a sound, press Start, and it runs in this browser tab. Nothing is downloaded, nothing is registered, and closing the page leaves nothing behind on the device.
