What is a Cron Expression?

A cron expression is a string of 5 fields separated by spaces that define a schedule for running tasks. It follows the standard format used by Linux cron, Quartz Scheduler, and many cloud schedulers.
  • Minute (0-59): Exact minute to run
  • Hour (0-23): Exact hour to run
  • Day of Month (1-31): Specific day to run, or * for any
  • Month (1-12): Specific month to run, or * for any
  • Day of Week (0-7): Day of week (0 or 7 = Sunday), or * for any

Use Cases

  • DevOps Automation: Define schedules for CI/CD pipelines, automated testing, and deployment tasks
  • Data Processing: Schedule ETL jobs, report generation, and data synchronization tasks
