Online alarm clock for 9:58 pm

As you hand the post to the incoming guard shift, a 9:58 pm alarm can keep the final checks from slipping past the changeover. There is just enough time to confirm the log, mention anything unusual and return shared gear before 10:00 pm. The alert marks a clear finish while the next guard takes responsibility.

Because the handover may take you away from the screen, leave the browser open and keep the phone or computer awake with the volume audible. Closing the page or letting the device sleep means the browser alarm cannot sound, so the guard shift could begin without the intended reminder. A quick glance at the visible countdown before moving to the handover point confirms that the alarm is still running.

Late-evening changeovers can involve moving between a bright office, a dim gate and an outdoor patrol area. Before 9:58 pm, set the screen brightness low enough that it does not spoil your adjustment to the darker surroundings, and place a torch where the incoming guard can reach it. If exterior lights use a timer, check their status during the handover rather than discovering an unlit access path after 10:00 pm.

Common questions

Can I set more than one alarm at a time?

This page is built around a single alarm at a time. For multiple alarms, open a separate tab for each one and set a different time in each, keeping every tab open until it's rung.

Why use a browser alarm instead of my phone's built-in one?

Mainly for reliability against silent mode, do-not-disturb, or a phone left charging out of earshot. It's a useful backup or a desk-based alternative, though it depends on this tab staying open rather than running in the background of your phone.

Is there a cost to use this?

No, it's free, with no sign-up and no limit on how many times you set it. It just needs the tab left open until the time you've chosen arrives.

Will the alarm still ring if I close the browser tab?

No. The alarm only runs while this tab stays open — closing it, or closing the browser entirely, stops the countdown before it can ring. Keep the tab open in the background if you need it to go off later.
