How to use the online alarm clock
As you hand over the final task of your shift, set the alarm for 8:33 pm so leaving for the last suburban train does not slip behind one more explanation. That gives you a clear moment to stop, collect your coat and check the platform before 9:00 pm, rather than watching the clock while your replacement settles in.
Your departure may need a gentle tone if you are working beside colleagues, but choose something more persistent if conversation or machinery could mask a quiet sound. Keep the alarm audible and leave the browser running while you finish the handover. The train plan could fail if the browser alarm stops running or the computer falls asleep, so use a separate alarm as a backup when missing that service would leave you stranded.
Once the handover is nearly complete, keep anything you eat before leaving light and easy to finish, with water close by rather than another drink that takes time to prepare. Save a larger evening meal for after the journey, especially if eating it now would delay your walk to the station. At 8:33 pm, packing a small snack for the train is more practical than starting something that keeps you in the break room.
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 8:33 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.
