Web alarm clock for 4:22 a.m.
You are preparing well ahead of your gate duty, and setting an alarm for 4:22 am gives you time to gather your torch, keys, logbook, and rain cover before changing the guard at the residential village entrance. The early alert leaves 38 minutes before 5:00 am, enough to check what must be handed over without rushing through the quiet compound.
Your gate handover depends on the alarm remaining active in the browser until 4:22 am. Choose the time, confirm that the alarm is armed, keep the browser page open, and leave your phone or computer awake with its volume audible. If you close the page or browser, or allow the device to sleep, the alarm cannot sound, so the guard change could be missed. A separate phone alarm is a sensible backup when punctual relief matters.
Before leaving for the gate, notice which sounds are still present near your quarters: an electric fan, dogs, occasional tricycles, or rain on the roof may mask the alert. By 4:22 am, neighbourhood noise can begin shifting as bakers, drivers, and early workers stir. Set a clear but moderate tone, place the phone within reach, and test its volume beforehand so that changing surroundings do not hide the signal.
