How to use the online alarm clock
As you finish what you are doing and head out to meet the bus from Gatwick Airport, an 8:39 pm alarm gives your departure a firm cue. It leaves a useful margin before 9:00 pm, whether you need to collect your keys, put on a coat or walk to the stop without rushing.
For this particular pickup, hearing the signal beforehand is more useful than discovering a volume problem when you should already be leaving. Set the alarm, use the available preview or test control, and listen from roughly where the phone will be placed. Check that the sound is distinct from ordinary notifications and audible over music or the television. Keep a separate backup for the bus, because this browser alarm cannot alert you after its page is closed or the phone has gone to sleep.
The route to an evening pickup may shift from a bright room to a dim pavement within minutes. Before 8:39 pm, place a small light near your keys or switch on the outside light so you can leave without searching in shadow. If you are walking to the stop, a charged phone torch or reflective layer can also make darker stretches easier to manage while you watch for the arriving bus.
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 8:39 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.
