Online alarm clock for 9:13 pm

Handing the local theatre rehearsal over to another crew member at 9:13 pm is easier when the finish point is already settled. Set the alarm for the moment they should take charge, then use the remaining evening to explain any lighting cues, prop changes or notes for the cast. If the handover runs towards 10:00 pm, the signal provides a clear boundary without interrupting every few minutes to check the clock.

A rehearsal room can be full of dialogue, music and movement, so choose a volume that can still be heard from where you will actually stand. Test it against the background noise before everyone begins, and keep the phone nearby rather than behind scenery or inside a bag. A browser alarm cannot protect the theatre handover if the page is no longer active or the phone has gone to sleep, so keep the session running and use a separate phone alarm when missing the cue would leave your replacement waiting.

Coming home after an evening rehearsal may mean other people in the house are already settling down. Use vibration alongside a moderate tone, place the phone close enough that you can respond quickly, and avoid sending the sound through a speaker in a shared room. At 9:13 pm, a short, distinctive signal can mark the changeover without waking children, housemates or anyone preparing for an early start.

Common questions

Does the alarm work if my laptop goes to sleep?

Not reliably. If the device sleeps or the screen locks, the browser tab pauses along with it, so the alarm may not fire on time or at all. Adjust your power settings if you're relying on this over a longer stretch.

Do I need to create an account or download anything?

No, there's nothing to sign up for and nothing to install. Pick a time and a sound, press Start, and it runs entirely in this browser tab.

Can I change the alarm sound?

Yes, there's a short list of tones to choose from before you press Start. Pick whichever one you're most likely to actually hear — softer sounds are easier to sleep through than a firm chime or bell.

What happens once the alarm goes off?

It rings through your device's speakers on a loop until you stop it from this page. There's no separate app notification, so make sure your volume is turned up before you rely on it.
