Pro tips

  • 6 fields, not 5. Always start with a seconds field — usually 0.
  • Set the zone. Cloud servers default to UTC. Add zone = "Asia/Kolkata" for human times.
  • Enable scheduling. Annotate a config class with @EnableScheduling or jobs are silently ignored.
  • Use names, not numbers for weekdays (MON-FRI) to dodge Quartz/Unix off-by-one bugs.
