How to use the online alarm clock
While you wait for the moment to collect your teenager from Army Cadets, set the alarm for 9:10 pm and keep an eye on the evening rather than repeatedly checking the clock. That leaves enough time before 10:00 pm to gather your keys, confirm where the club finishes and be ready to leave without rushing.
Your Army Cadets pickup could easily be missed if the alarm sound is quietly routed to headphones lying in a pocket or another room. Check the audio output after setting the time, then use the test sound if available and raise the volume to a level you will notice. Keep this page running and the phone awake; otherwise the Army Cadets alarm may pass without making any sound.
Waiting to head out at 9:10 pm can affect everyone settling down at home, especially when keys, shoes and coats are gathered at the last minute. Put what you need near the door earlier in the evening, and choose an alarm volume that reaches you without carrying through bedrooms. A short vibration alongside the sound can provide a discreet extra cue while keeping the household quieter.
Common questions
What happens if my laptop goes to sleep before 9:10 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.
