Compatible with standard Unix cron, GitHub Actions, Kubernetes CronJob, and most scheduling systems. Use * for “every”, */5 for “every 5”, 1-5 for ranges, 1,15 for specific values.
GitHub Actions tips
GitHub Actions schedule cron runs in UTC. The "next 5 runs" preview shows your local time — mentally subtract your UTC offset to get the actual scheduled times.
GitHub may not run scheduled workflows during high traffic times. For time-critical jobs, schedule outside US business hours.
Common pattern: `0 9 * * 1` runs every Monday at 9 UTC — good for weekly digest jobs.
