How to use the online alarm clock
While you wait for the moment to leave for a West End matinee, set the alarm for 1:15 pm and keep an eye on the time without repeatedly checking the clock. The alert gives your afternoon a clear turning point: finish what you are doing, gather your ticket and belongings, then start towards the theatre. There are 45 minutes until 2:00 pm, enough to move from waiting into the practical part of the outing.
Your performance plans depend on the alarm page remaining open in the browser and the computer or phone staying awake; if either is closed or goes to sleep, the alert may not sound. Leave the page running where you can hear it, keep the volume at a useful level, and avoid switching the screen off if that makes the device sleep. A separate phone alarm is sensible when missing 1:15 pm would leave too little time to reach the theatre.
Getting to a matinee around midday can take longer than the map’s bare journey estimate suggests. Allow time for a walk to the station, waiting for a Tube or bus, and crossing busy streets near the West End. Check for service changes before 1:15 pm, and aim to reach the theatre early enough for ticket checks and finding your seat without rushing.
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 1:15 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.
