How to use the online alarm clock
Waking at 11:30 pm gives you a moment to shake off the sleep before moving your car from a daytime restricted zone. Check the parking sign and gather your keys while you become fully alert; the half-hour before 12:00 am leaves room to confirm that the restriction has ended rather than heading outside immediately.
Your car move could be missed if the alarm sounds through headphones left connected across the room. Before settling back down, test where the audio is playing and set the volume at a level you can hear from bed. Keep this browser alarm running and the computer awake, because it cannot give the signal for the car once the browser session ends or the machine goes to sleep. A separate phone alarm adds a useful fallback if leaving the vehicle where it is could cause trouble.
Moving a car late in the evening can disturb people who are already asleep, especially when keys, doors and an engine carry through a quiet house. Put shoes and a coat near the exit beforehand, hold the keys rather than letting them jangle, and close the front door gently. At 11:30 pm, avoiding repeated trips between the bedroom and hallway keeps the departure brief and reduces noise for everyone else at home.
Common questions
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.
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.
