Web alarm clock for 12:47 a.m.
As you finish firing the roadside bakery oven and prepare to leave, set the alarm for 12:47 am so the last check does not slip past you. The short stretch before 1:00 am is enough to confirm that the fire has caught, put your tools away, and hand over any note for the next baker. Keep the phone where you can hear it while you close up.
During that final oven check, sound can quietly switch to earphones left connected in a pocket or on a nearby counter. After setting 12:47 am, play a quick test and look at the audio output shown on your phone; disconnect the earphones if the alarm is not coming through the speaker. A browser alarm cannot alert you once its page is closed or the phone goes to sleep, so your bakery departure could happen before the warning sounds.
Leaving the bakery after midnight can mean stepping from an air-conditioned room into the warm Philippine night. Before you go, keep the cooling moderate near the oven area rather than making the room sharply cold, and place your keys and water together by the exit. That small setup helps you complete the 12:47 am check without lingering in the heat from the fire or searching around before locking up.
