How to use the online alarm clock
As you hand the final stretch of the National Trail to another walker, an alarm for 6:52 pm marks the point when they need to take over and finish the route in daylight. That leaves a clear checkpoint before 7:00 pm for passing on the map, the remaining distance and any awkward junctions ahead.
During the handover, the alarm page can remain visible so both walkers can confirm the time without relying on memory. The phone’s silent setting may suppress the sound, so the volume and audible alerts need checking before the new walker sets off. If the browser is no longer running or the phone falls asleep, the alarm may not sound, which could leave the trail changeover unnoticed when daylight is limited.
For a late-afternoon changeover at 6:52 pm, estimate the road journey to the collection point as carefully as the walking distance. Rural lanes near a National Trail can take longer than their mileage suggests, particularly around village traffic or single-track sections. Allowing for the actual drive helps the outgoing walker choose a handover place that can be reached before fading light makes signs, gates and roadside parking harder to spot.
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 6:52 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.
