How to use the online alarm clock

Finish sorting the last letters, secure the depot area and leave ready to begin the postman’s route to the outlying cottages. An alarm set for 1:59 pm gives a clear cue to stop the final check rather than letting one more small job delay departure. With 2:00 pm only a minute away, keys, delivery bag and route notes should already be in hand.

Because the route begins as the working day moves on, the alarm needs a reliable place to keep running until it sounds. Check that the volume is audible, leave this browser available and prevent the phone or computer from falling asleep beforehand. If the browser stops or the equipment sleeps, the alarm may stay silent and the postman’s route could begin late. A separate phone alarm is sensible when leaving on time cannot depend on the browser remaining active.

Before setting off for remote cottages at midday, note what follows the round later that afternoon. Allow enough spare time for traffic on narrow country lanes, awkward gates and a brief return to the sorting office without squeezing the next same-day commitment. At 1:59 pm, that buffer is easier to preserve by leaving promptly, carrying water and checking the first few stops before moving away.

Common questions

What happens if my laptop goes to sleep before 1:59 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.
