How to use the online alarm clock

You’re finishing what you’re doing and heading out to take your child to Brownies when the 4:45 pm alarm sounds. It gives you a clear cue to gather their uniform, water bottle and anything needed for the session, then leave without repeatedly checking the clock. With 5:00 pm approaching, those fifteen minutes can cover coats, shoes and the short shuffle from front door to car or pavement.

Brownies departure time is easy to miss if tidying up or one last household job runs on. The alarm can stay ready in the background while you finish, provided the browser remains open and the phone or laptop stays awake. If the page is closed or the device goes to sleep, no alert will play, which could make your child late for Brownies. The sound also needs to be loud enough to reach you from the next room.

Leaving for an afternoon activity works more smoothly when 4:45 pm includes a small buffer rather than marking the latest possible departure. Allow for a missing badge, a toilet stop, wet weather or traffic near the meeting place. If another commitment follows Brownies later that day, keep its essentials separate so the spare minutes before leaving are not spent unpacking and repacking the same bag.

Common questions

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.

Does the alarm still work if I close the tab?

No. Everything runs inside this page, so closing the tab — or quitting the browser altogether — ends the countdown there and then. Leaving it open in the background is all it asks, and switching to another tab makes no difference.

What happens if my laptop goes to sleep before 4:45 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.
