- What is a cron expression?
- A cron expression is a string of five space-separated fields (minute, hour, day of month, month, day of week) that defines a recurring schedule. It is used by crontab, cloud schedulers, CI/CD tools, and many other systems.
- What does each field mean?
- Minute (0-59), Hour (0-23), Day of Month (1-31), Month (1-12), Day of Week (0-6, Sunday=0). An asterisk (*) means every value, comma separates values, hyphen defines a range, and slash defines a step.
- How do I schedule a cron job every 5 minutes?
- Use */5 * * * *. The */5 in the minute field means every 5th minute. Use the same pattern for other intervals: */15 for every 15 minutes, */30 for every 30 minutes.
- Is this compatible with my platform?
- Yes. This tool generates standard 5-field cron expressions compatible with Linux crontab, AWS CloudWatch/EventBridge, Google Cloud Scheduler, Azure Functions, GitHub Actions, Jenkins, and Kubernetes CronJobs.
