Kubernetes CronJob timezone depends on the kube-controller-manager / CronJobTimeZone feature. Many clusters still interpret schedules in the controller’s local time (often UTC).

Kubernetes CronJob schedules

A CronJob uses the standard 5-field Unix cron syntax in spec.schedule. Optionally set spec.timeZone when your cluster supports the CronJob time zone feature.

What this tool generates

A ready-to-adapt batch/v1 CronJob YAML snippet
Plain-English explanation of the schedule
Timezone-aware next run previews (verify against your cluster)

Caveats

Without timeZone, many clusters interpret the schedule in the controller manager's local time (often UTC).
Use concurrencyPolicy, history limits, and deadlines to avoid overlapping or stuck jobs.
