What cron syntax is supported?

Standard 5-field POSIX cron (minute, hour, day-of-month, month, day-of-week).

Are step values like */5 supported?

Yes. Step, range, list, and the wildcard `*` are all supported.

Does it understand `@daily` style aliases?

Yes — `@yearly`, `@monthly`, `@weekly`, `@daily`, and `@hourly` map to their classic equivalents.

Why does timezone matter?

DST transitions and local-time schedules shift fire times — choose the timezone the cron runs in.

Is this for Linux cron or Kubernetes CronJob?

Both — Kubernetes CronJob uses standard POSIX cron syntax, so the same expressions work.

How many future fires can I preview?

1 to 20. Useful for sanity-checking a schedule before deploying.
