Web alarm clock for 4:28 a.m.
You are watching the clock at 4:28 am, waiting for the moment to check the rice paddies before the overnight irrigation begins. Set the alarm for this exact time so the planned inspection does not slip while you prepare a torch, boots, and notes for the field. With 5:00 am approaching, there is still room to examine the bunds and water gates before the next part of the morning starts.
Your rice paddy check depends on the browser remaining open until the alarm sounds. If you close this tab or the browser, the alert will not run; it may also fail if your phone or computer goes to sleep. Keep this page visible, leave the device awake, and turn the sound high enough to hear over an electric fan or other early-morning noise. A charger nearby can help prevent the session from ending before 4:28 am.
Once the rice paddy check is finished, protect a little space before the next task scheduled for the same day. Use the remaining night hours to record the water level, any blocked channel, and which gate needs attention after sunrise. Keeping those details together reduces the chance of carrying an unfinished field question into breakfast preparations or the first daytime job.
