Quartz cron expression format

Quartz (and Spring @Scheduled) uses 6 or 7 fields, starting with seconds. Day-of-month and day-of-week are mutually exclusive — use ? for one of them.

  • Fields: second minute hour day-of-month month day-of-week [year]
  • Seconds field enables sub-minute precision (e.g. 0 for top of the minute)
  • Special chars: ? L W # for advanced day rules
  • Year is optional as the 7th field
  • MON-FRI and numeric weekdays are both valid
  • Ideal for Spring Boot @Scheduled and Quartz Scheduler

Spring Boot @Scheduled

@Scheduled(cron = "0 0 9 ? * MON-FRI *")
public void weekdayMorningJob() {
    // runs Mon–Fri at 09:00:00
}

FAQ

Quartz adds a leading seconds field (and an optional year). A 5-field Linux expression is not valid in Quartz without adding seconds — usually 0 at the start.
