How to use the online alarm clock
Waiting to meet the last train at the station, you are watching the minutes rather than trying to fall asleep. Set the alarm for 1:41 am so you have a clear cue to gather your coat, check the platform information and move towards the arrival point. If the service is due nearer 2:00 am, the alarm can also mark the moment to make a final check without repeatedly looking at the clock.
Station announcements, passing traffic or conversation on the platform can easily cover a quiet browser signal. Set the volume before settling down to wait, then play a brief test sound at the same level of background noise you expect later. Keep headphones off unless you will be wearing them when the alarm sounds. Do not rely on this alarm after closing its page or allowing the computer to sleep: the last train could reach the station without any signal being heard.
During a 1:41 am wait, keep the screen dim and place it slightly below eye level instead of holding a bright display close to your face. Use the alarm as the main prompt, leaving the clock visible only when you need to check it. Between checks, turn the screen away from direct view while staying where the platform boards and approaching train remain easy to see.
Common questions
What happens if my laptop goes to sleep before 1:41 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.
