How to use the online alarm clock
Waking at 7:02 pm leaves the evening untouched, but catching the last suburban train now depends on getting moving promptly. There is enough room before 8:00 pm to dress, gather your keys and check the station departure board without drifting back under the duvet. Treat the alarm as the point when preparation begins, not as permission for another few minutes in bed.
Because this alert matters for a fixed departure, test its sound before relying on it. Set a temporary alarm a minute ahead, keep the volume at a level you can hear from across the room, and confirm that the browser is allowed to play audio. Then replace the test with 7:02 pm. Keep the alarm running on an awake screen until it sounds; if it becomes inactive, the silence could leave you missing the last suburban train.
Getting up in the evening can make the remaining hours feel less definite than a morning schedule. Leave a clear buffer between reaching the station and the final train, then reserve another small block after the journey for whatever comes next that night. Packing a charger, travel card and any overnight essentials together now prevents the 58 minutes before 8:00 pm from disappearing into separate searches around the house.
Common questions
What happens if my laptop goes to sleep before 7:02 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.
