Scheduling Python jobs across Thai public holidays

Most automation courses treat calendars as an afterthought. In Thailand, public holidays shift workloads dramatically: finance queues pause while logistics spikes before long weekends. We teach learners to encode holiday tables explicitly, separate business-hour checks from UTC storage, and document assumptions in runbooks teammates can challenge politely.

Bridgemesh labs start with a synthetic holiday file you version alongside code. You practice injecting blackout windows into APScheduler and systemd timers, then simulate a surprise bridge holiday declared mid-sprint. The goal is not perfect prediction—it is readable failure when calendars disagree with reality.

We also discuss human notification etiquette. A script that pings LINE groups during family dinners erodes trust faster than a missed job. Cohort mentors review quiet-hour configs as carefully as retry logic.

Capstone teams must show how their scheduler behaves when the holiday file is wrong—rollback paths matter as much as happy paths.
