Web alarm clock for 4:57 a.m.
You are preparing early to inspect the rice paddies before the overnight irrigation begins, so setting an alarm for 4:57 am gives you a clear moment to put on boots, gather a flashlight, and head out. The alert comes just before 5:00 am, leaving enough time to check the first bund and water gate before the new hour starts.
Your rice-paddy check may depend on hearing the alert while you finish another task on your phone. If the alarm page moves into the background, your browser may reduce its activity or delay its sound, especially when power-saving settings take over. Keep the page active and the phone awake with the volume audible. If you close the page or let the phone sleep, the alarm cannot reliably signal the rice paddies inspection, so use a separate device alarm as backup when timing affects irrigation.
Before walking out into the dark, notice how the cool air indoors can hide the heat waiting outside. At 4:57 am, air-conditioning may make the temperature change feel abrupt once you reach the paddies, even before sunrise. Set out a light outer layer that is easy to remove, take drinking water, and place your flashlight where you can grab it without searching through a bag. That keeps the early inspection practical as the humid Philippine morning begins to warm.
