How to use the online alarm clock

Packing the glass safely now means the recycling-centre trip will not become a last-minute scramble. An alarm for 2:35 pm can mark the point for putting on shoes, collecting the box and checking the route before leaving. That still leaves the journey under way ahead of 3:00 pm, rather than letting the next round hour quietly pass.

Because the reminder is needed before setting off with glass, the browser must remain able to run until 2:35 pm. A phone or laptop that goes to sleep too soon may silence the alarm, while closing this page can stop it altogether and leave the glass waiting at home. Keeping the page open, leaving the sound audible and preventing automatic sleep until the alert has sounded gives the tool a fair chance to do its job.

A midday departure can involve sharp changes in light between the house, the street and a covered recycling area. Before 2:35 pm, placing sunglasses beside the glass box avoids searching for them at the door, while turning up the screen brightness makes the alarm easier to see outdoors. If the sky is dull, keeping a small torch near the box can also help when checking that no loose shards remain in the boot.

Common questions

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 2:35 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.
