Cron syntax & daylight saving
Use * for every value, commas for a list, a dash for a range, and / for steps. Five-field Unix cron has no seconds field. When both day-of-month and weekday are restricted, either matching day can trigger a run.
Preview dates account for timezone offsets and daylight saving using cron-parser. Schedulers may handle skipped or repeated local times differently; check the runtime you deploy to.
