How to use the online alarm clock
While you watch the clock for the right moment to collect your schoolchild from after-school club, an alarm for 3:11 pm lets you wait without repeatedly checking the minutes. It gives you a clear cue to gather your keys and leave with enough time for the journey. If your afternoon is arranged around 4:00 pm, the earlier alert also leaves a useful margin for the pick-up and the trip home.
For a school-club collection, the signal needs to be audible over conversation, television or kitchen noise. Set the volume before relying on the alarm, then play a brief test if the room is busy or your phone is across the room. Keep the browser running and the phone awake until 3:11 pm; otherwise the alarm cannot remind you to collect the schoolchild. If background sound changes while you wait, keep the phone nearby rather than assuming the original volume will still carry.
As the afternoon begins to fade, changing light can make it surprisingly easy to lose track of time while reading or finishing a household task. Before settling down to wait, switch on a lamp near where you will be sitting and place your keys somewhere visible in that pool of light. At 3:11 pm, you can respond to the alarm without searching a dim hallway, and brighter surroundings can help mark the transition from waiting at home to heading out for the school-club pick-up.
Common questions
What happens if my laptop goes to sleep before 3:11 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.
