Online alarm clock for 7:43 pm

You are waking at 7:43 pm with the choir rehearsal hall still locked and the evening not yet under way. Set the alarm for this exact time so you can get up, collect the keys and be ready to open the hall before 8:00 pm. The alert gives your first few minutes a clear purpose while you shake off the heaviness of sleep.

Because your route to the hall depends on hearing the alert, leave this alarm page visible while it is running. Moving to another app or letting the browser sit in the background can cause the page to be paused by your phone. If the browser session ends or the phone goes to sleep, the alarm cannot alert you for the choir rehearsal. Keep the screen awake, raise the volume and check that silent mode will not suppress browser sound.

Once the hall is open, keep the rest of the evening deliberately quiet if you intend to sleep again afterwards. Put the keys, coat and anything needed for rehearsal together before lying down, so waking at 7:43 pm does not turn into a longer search. Avoid settling into another evening task before leaving; a short, direct routine makes it easier to return home and preserve the sleep still available later.

Common questions

Can I change the sound?

Yes, there is a short list of tones to pick from before you press Start. Softer sounds are easy to sleep through, so a firmer bell tends to be the safer choice for anything early in the morning.

Will it still be right when the clocks change?

Yes. It reads your device's local clock, so the move between GMT and BST at the end of March and October is picked up automatically, as long as the computer's date, time and time zone are set correctly.

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.
