About this Cron Expression Parser

Cron expressions schedule recurring jobs in CI, Kubernetes, and classic Unix cron. Fields for minute, hour, day of month, month, and day of week are easy to misread—especially with ranges and steps.

A human-readable description and next-run preview reduce production mistakes like “ran every minute instead of daily.”

How to use this tool

  1. Paste a cron expression (check whether your system uses 5- or 6-field cron).
  2. Read the plain-language explanation.
  3. Review next run times if shown.
  4. Copy the verified expression into your scheduler.

Common use cases

FAQ

Do all systems share the same cron dialect?

No. AWS, Kubernetes, and Quartz differ. Confirm field count and timezone.
