How to use the online alarm clock
While you wait for the moment to leave for your castle tour, a 2:31 pm alarm keeps the afternoon from slipping away while you watch the clock. It gives you a clear cue before 3:00 pm, so you can gather your coat, ticket and directions without setting off prematurely or becoming absorbed in something else.
For a castle tour, hearing the alert clearly matters more than merely seeing that it has been set. A quick test beforehand lets you check the selected sound and adjust the volume while there is still time to fix anything. Keep this browser page available and the computer or phone awake: otherwise, the castle tour reminder will not sound when you need to leave. The test also confirms that silent mode, connected headphones or nearby noise will not hide the signal.
With the departure point approaching in the middle of the afternoon, a small drink of water is easy to finish before setting out. A light snack may also fit the wait if the tour is lengthy, but a full meal is better left until afterwards if it could make you late. Packing a bottle now avoids searching for one near the entrance, where options may be limited.
Common questions
What happens if my laptop goes to sleep before 2:31 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.
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.
