How to use the online alarm clock
While getting ready for tea with the neighbours, you can set a 5:47 pm alarm before the last-minute rush begins. That leaves a useful prompt to collect your keys, put on a coat and check whether you are taking anything with you. With 6:00 pm approaching, the alarm can mark the point when preparation turns into leaving.
A punctual arrival for tea depends on hearing the alert, so check how silent mode affects browser audio on your phone. Raising the media volume may be necessary even when calls and messages are muted, and a quick test can confirm what will actually be audible. The browser must remain running and the phone awake; otherwise the alarm will not sound and the planned tea arrival can slip. Keeping the phone nearby also prevents a quiet alert being missed in another room.
Leaving for the neighbours in the late afternoon may overlap with someone cooking, watching television or settling a child at home. A moderate alarm tone at 5:47 pm can be heard without startling everyone nearby. If another person shares the room, vibration alongside a lower volume offers a discreet prompt. Preparing shoes and anything you are bringing beforehand also reduces noise and hurried movement as 6:00 pm draws close.
Common questions
What happens if my laptop goes to sleep before 5:47 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.
