How to use the online alarm clock
While you wait to unlock the choir rehearsal hall, set the alarm for 10:16 pm and keep an eye on the displayed time. It gives you a clear cue to fetch the keys, check the entrance and open up at the agreed moment, rather than drifting towards 11:00 pm while everyone gathers outside.
A busy hall entrance can make a quiet alert surprisingly easy to miss: conversation, traffic and people moving equipment may cover the sound. Set the volume high enough to carry over that background noise, then use the preview to judge it from wherever you will be waiting. Keep the alarm running and your phone awake; otherwise the signal may never sound, leaving the rehearsal hall locked when the choir arrives. A vibration alert can provide an extra prompt if the phone is in your pocket.
With a late-evening rehearsal about to begin, a small drink of water is practical before you unlock the hall, especially if you will be singing too. A heavy meal or several hot drinks may be awkward once people start arriving and need directions, so leave those until the room is open and the first rush has settled.
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 10:16 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.
