How to use the online alarm clock
You are watching the clock, ready to leave at the appointed moment and reach the commuter station before its car park fills. An alarm set for 8:00 am lets you keep gathering your keys, travel card and work bag without repeatedly checking the time. When the alert sounds, you will know it is time to head out and try for a parking space before the morning rush grows busier.
Keep this alarm page open while you wait, with the sound turned up enough to hear from where you are getting ready. Closing the page ends the alarm, and a sleeping phone or computer may prevent it from sounding, so it cannot safeguard your plan to secure station parking. If leaving on time matters, check that power-saving settings will not silence the alert and use a separate alarm as a fallback.
While you wait to leave in the early morning, place the screen where a quick glance is enough instead of holding it close and staring at the countdown. Reduce the brightness if the display feels harsh in dim indoor light, but keep the figures readable. Setting your coat, keys and travel card beside the phone also limits repeated screen checks and makes the 8:00 am departure easier to follow.
Common questions
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.
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.
