How to use the online alarm clock
Waking at 1:05 pm leaves you just enough time to get your bearings before heading out to watch the Changing of the Guard at the palace. An alarm at this precise minute can mark the end of a late lie-in without turning the afternoon into a rush. With 2:00 pm approaching, you still have time to get dressed, check your route and gather what you need for the journey across London.
Your palace plans depend on the alarm being able to make a sound while you are getting ready. Choose a tone you can hear from across the room and check the volume before relying on it. If this page is closed or your phone or laptop falls asleep, the browser alarm will not ring, which could leave your palace visit starting later than intended. Keeping the machine awake until 1:05 pm avoids that silent failure.
Coming round at midday can make a bright screen feel unnecessarily harsh, especially if the curtains are still drawn. Lowering the display brightness before looking at directions or transport details gives your eyes a gentler transition into the afternoon light. Once you are up, letting daylight into the room can make the screen easier to read without increasing its brightness. That also helps when checking the route briefly rather than lingering over the phone.
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 1:05 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.
