How to use the online alarm clock
You have only just woken, and meeting a train at King’s Cross now depends on getting moving without drifting back to sleep. An alarm for 1:55 pm gives you a firm moment to leave the bed, check the departure details and gather what you need. With 2:00 pm approaching, there is little room for a slow start.
Your King’s Cross journey can stay in view while the alarm page sits behind another app or browser page. Background activity may be restricted by battery-saving settings, so the alarm deserves a quick sound check before you rely on it. If you close its browser page or let your phone or laptop sleep, no signal can play and you may miss the train. Leaving the browser running in the background avoids accidentally cancelling this reminder.
Getting from a rushed wake-up to King’s Cross can feel harsher when a warm midday street follows a cool room. At 1:55 pm, allow a moment away from strong air conditioning before heading outside, and take some water for the journey. Keeping the room comfortably cool rather than icy makes the change in temperature less abrupt while you collect your bag and leave.
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 1:55 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.
