How to use the online alarm clock

Waking at 12:13 pm with a child to collect after a half-day at school can make the afternoon feel suddenly close. The alarm marks the moment to get out of bed, check the school’s collection arrangements and allow time for the journey. There are 47 minutes until 1:00 pm, enough to get dressed and gather anything your child needs without losing sight of when you must leave.

For this school pickup, the alarm needs to remain able to run while you get ready. If you close its browser tab or browser, or allow the phone or computer to sleep, the child-collection alert will not sound. Keep the page open on an awake device, set the volume to a level you can hear from the next room, and check that silent mode will not suppress the sound.

Because this is a midday pickup rather than the end of the school day, the next commitment may follow quite soon. Work backwards from the collection time and reserve a small buffer for traffic, parking near the school or a delayed bus. Keeping that margin separate from dressing and travel time helps prevent an unexpected hold-up from affecting the rest of the afternoon.

Common questions

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.

Can I use this on a phone?

It works in a mobile browser, but phones lock the screen and suspend background tabs far more readily than a laptop does, which can stop the alarm sounding. For anything important, a desktop or a plugged-in laptop is the steadier option.
