How to use the online alarm clock
Finish what you are doing and leave for the GP reception when the 2:40 pm alarm sounds. That gives you 20 minutes before 3:00 pm, enough time to gather your keys, check which document you need and set off without letting the afternoon drift. The reminder suits a certificate collection that is easy to postpone when another small task gets in the way.
While getting ready to collect the certificate, check where the alarm sound will play. A connected pair of headphones may receive it without you noticing, especially if they are in a pocket or another room, so the phone speaker can appear silent. Set a clear volume and test the alert before depending on it. This browser alarm will not sound after its page is closed or the phone has gone to sleep, which could leave the certificate waiting at reception.
Leaving for the surgery around 2:40 pm can put the journey close to school-run traffic, busier junctions and reduced parking availability. Allow for the route you will actually take at midday rather than assuming an off-peak travel time. If reception closes for an afternoon break or has a fixed collection window, keeping a little journey margin before 3:00 pm makes a late bus or slow queue less likely to derail the trip.
Common questions
What happens if my laptop goes to sleep before 2:40 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.
