How to use the online alarm clock
Pause midway through setting out the pantomime props and set the alarm for 10:08 pm, so you have a clear cue to step away from the job. That leaves the remaining sorting and placement to fit around a definite stopping point rather than drifting towards 11:00 pm. It is particularly useful backstage, where a half-finished scene change can easily absorb more attention than expected.
Before returning to the props, play a test signal and check that it is loud enough to carry across the space where you are working. Keep the sound level and browser conditions unchanged afterwards, so the real alert behaves like the one you tested. The pantomime props may remain unfinished if the browser is no longer running or the computer has gone to sleep when 10:08 pm arrives, so use a separate alarm when missing the cue would disrupt the rehearsal.
While arranging scenery on a warm evening, notice whether the air conditioning masks short or high-pitched sounds. At this hour, a fan may also be running close to the work area, adding steady background noise. Place the computer away from the strongest airflow, choose a distinct tone, and leave enough volume for the signal to be heard without startling anyone elsewhere in the theatre.
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 10:08 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.
