How to use the online alarm clock
Handing the West End collection over to another driver at 3:54 am means passing on the timing as well as the destination. The alarm marks the moment they need to set off for the theatre after the late performance, with 4:00 am close enough to serve as a clear final checkpoint before departure.
During the handover, this alarm page may slip behind maps, messages or parking details. A background page can be slowed by the browser, so leaving its sound enabled and returning it to the foreground before the agreed time reduces uncertainty. The alarm cannot safeguard the crew collection if the browser has stopped running or the phone has gone to sleep; a separate phone alarm is a sensible fallback for the driver taking over.
Once the theatre pickup is assigned, the next commitment later that day needs its own margin rather than whatever time happens to remain. At this hour, note the expected return time and allow a short buffer before the following alarm. That keeps a delayed stage exit, road closure or longer journey from quietly consuming the rest available before the next task.
Common questions
What happens if my laptop goes to sleep before 3:54 am?
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.
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.
