Web alarm clock for 2:45 p.m.
While you wait for the right moment to bring lunch to your relative in the rice field, set the alarm for 2:45 pm and keep an eye on the remaining preparations. That leaves a useful stretch before 3:00 pm for packing the rice and ulam securely, filling a water bottle, and checking that everything will travel without spilling.
A lunch delivery across open fields may call for a tone that can be heard over wind, conversation, or farm equipment. Choose a firm, persistent sound if you might set the phone down while packing; a softer tone suits a quiet room when the phone stays beside you. Keep the browser active and the phone awake: otherwise, the lunch alarm may stay silent and delay your departure for the rice field.
Your relative's lunch should arrive when expected, so include the midday journey in your timing rather than treating 2:45 pm as the moment to begin getting ready. Allow for the walk from the roadside or barangay path into the field, especially where the ground is uneven or sun-exposed. Pack before the alarm, estimate the route from your actual starting point, and leave a small buffer for a tricycle wait, a railway crossing, or a slower final stretch between paddies.
