How to use the online alarm clock

As you hand rugby pitch preparation over to the next groundskeeper at 3:47 pm, use the alarm to mark the exact change of responsibility. There are thirteen minutes before 4:00 pm, enough for a quick account of the touchlines, posts, corner flags and any equipment still waiting by the field.

Before leaving the pitch, check the alarm at a volume the incoming groundskeeper can actually hear, especially if the computer is set to silent or its sound has been muted. A visible countdown is useful confirmation, but it does not replace an audible check. If the browser is closed or the computer goes to sleep, the alarm will not sound, so the rugby handover could run late; keep the page open and the computer awake until it rings.

Late-afternoon light can put reflections across the screen while you are moving between the clubhouse and the field. Angle the display away from the low sun, raise the text size if needed, and confirm 3:47 pm without staring at a bright panel. Once the setting is clear, lower the screen brightness to suit the surrounding light and return your attention to the pitch handover.

Common questions

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 3:47 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.
