How to use the online alarm clock

While you wait for the cue, use the alarm for 10:23 pm to time when the pantomime props need to be set out. There is no need to keep checking the clock while watching for the appointed moment. With 11:00 pm still ahead, the alert can separate this cue from the next part of the evening’s preparations.

During a quiet backstage wait, sound can slip into connected headphones without anyone nearby hearing it. Check where a test tone plays, then set the volume high enough for the alarm to cut through conversation and movement around the wings. Your pantomime props may miss their cue if the browser alarm stops running before 10:23 pm, so keep the session active and the computer awake until it sounds. A separate alarm clock is sensible if leaving the browser running cannot be guaranteed.

Once the props are ready, reduce the screen brightness so repeated clock checks do not feel harsh under dim backstage lighting. Keep the time display large enough to read at a glance and place the screen slightly to one side rather than directly in front of your eyes. At this point in the evening, a warmer display setting can also make the remaining checks more comfortable without obscuring 10:23 pm.

Common questions

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 10:23 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.

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.
