How to use the online alarm clock
Breaking away from what you are doing for an evening college course can be harder than noticing the clock, so a 7:38 pm alarm gives the change of activity a clear boundary. It can mark the moment to gather your notebook, check your route and leave without drifting towards 8:00 pm still occupied with the previous job.
Your course reminder needs to be audible, which makes the sound settings worth checking before relying on it. Silent mode may suppress the alert even when the alarm itself is correctly set, so a quick sound test can confirm what you will actually hear at 7:38 pm. Because this browser alarm cannot sound once its page is closed or the phone is asleep, it should not be the only reminder for your college course; a separate phone alarm provides sensible cover.
Heading to college during a British evening may mean stepping from a warm room into damp, close air, particularly after rain. Checking the humidity and outdoor conditions while packing helps with a practical choice between a light waterproof and an extra layer that may feel uncomfortable on the walk. Keeping either option beside your course bag also avoids searching for it when the alarm sounds.
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 7:38 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.
