About this tool
Cron is the standard Unix job scheduler, widely used in Linux, Kubernetes CronJobs, CI/CD pipelines, and cloud functions. A 5-field expression defines: minute (0–59), hour (0–23), day-of-month (1–31), month (1–12), and day-of-week (0–7, where both 0 and 7 mean Sunday). Supported syntax: * (any), */n (every nth), a-b (range), a-b/n (stepped range), and comma-separated lists. Next-fire calculations are based on your browser's local clock and timezone: production schedulers may run in UTC, so verify timezone settings before relying on timing-critical jobs.
