How to use the online alarm clock

Watching the clock while you wait to collect the crew after a late West End performance, set the alarm for 2:34 am so the agreed departure does not slip. That still leaves a useful stretch before 3:00 am, enough to check the theatre exit, confirm where the vehicle can stop and keep an eye on any overnight road changes.

With the alarm page running behind your map or messages, the browser may reduce its activity, so return to it briefly and check that the time is still advancing. Keep the sound audible and the page open while you wait. If the browser is closed completely or the phone goes to sleep, the alarm may not sound, which could leave the crew standing outside after the performance.

Once the pickup is finished, judge the remaining night by the next commitment later that same day rather than treating 2:34 am as spare daytime. Leave a clear buffer for the drive home, parking and settling in before anything else begins. If another alarm is needed, set it before leaving the West End, while the schedule and journey time are still fresh.

Common questions

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.

Can I use this on a phone?

It works in a mobile browser, but phones lock the screen and suspend background tabs far more readily than a laptop does, which can stop the alarm sounding. For anything important, a desktop or a plugged-in laptop is the steadier option.

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 2:34 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.
