How to use the online alarm clock
Waking just before the bell-ringers’ tower round leaves little room for a slow start. An alarm for 9:18 pm gives you a clear moment to get up, dress and gather anything needed before joining them. With the clock moving towards 10:00 pm, you can use the remaining time for the journey and arrive ready for the evening’s work rather than still shaking off sleep.
Your late wake-up makes the alarm’s reliability part of the bell-tower plan. Check that the displayed time is 9:18 pm and leave the alarm page running with the sound audible. If your phone or computer falls asleep, or the page is closed, the browser alarm will not ring; the bell-ringers may start their round while you are still at home. A separate phone alarm is a sensible backup when punctual arrival matters.
Climbing into a tower after a warm British evening can feel stuffier than the street outside, especially after waking in an air-conditioned room. Before leaving at 9:18 pm, allow a few minutes for the temperature change, take some water and choose a light layer that can be removed inside. Setting the air conditioning slightly less cool before getting up can also make the move from indoors to the evening heat feel less abrupt.
Common questions
What happens if my laptop goes to sleep before 9:18 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.
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.
