What Cron Parser does
A standard cron expression defines minute, hour, day of month, month, and day of week. This parser explains common wildcards, steps, ranges, and lists.
Common uses
- Review a scheduled job
- Catch out-of-range fields
- Explain a CI or Kubernetes CronJob schedule
Privacy and limitations
The expression is parsed locally. Always verify which cron dialect and timezone your platform uses.
Always validate security-sensitive output in the authoritative application or platform.
Frequently asked questions
Does this support seconds?
The first version targets classic five-field cron. Quartz and some schedulers add a seconds field.
Which timezone is used?
Cron uses the scheduler's configured timezone, not necessarily your browser timezone.
