How to use the online alarm clock
Finish what you are doing and set off at 1:31 pm to meet the sightseeing boat by the canal lock. That leaves a clear margin before 2:00 pm for walking along the towpath, finding the correct gate and allowing for a slowly opening lock. Keep the meeting point written down, as canal paths and nearby streets can look deceptively similar.
For this boat rendezvous, test the alarm sound now rather than discovering a problem when departure time arrives. Set 1:31 pm briefly, check that the volume is audible over conversation or traffic, then reset it for the time you actually need. Choose a distinct tone and keep the browser active. Do not make this alarm the sole safeguard for the boat meeting: it will not sound once the page is closed or if the phone goes to sleep.
After meeting the boat around midday, protect whatever sleep remains in your plans by deciding beforehand whether any later nap has a firm end time. A second alarm can mark that boundary without mixing it up with the 1:31 pm departure cue. If tonight’s sleep matters more, use the journey home as a quiet wind-down rather than letting an unplanned afternoon doze run on.
Common questions
What happens if my laptop goes to sleep before 1:31 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.
