Every weekday at 9 AM in cron

The day-of-week field uses 0–6 with Sunday as 0 (most implementations also accept 7 for Sunday). 1-5 is Monday to Friday; most crons also accept the names MON-FRI.

Cron has no notion of public holidays. If the job must not run on holidays, let it run and have the script check a calendar file first, or trigger it from a scheduler that supports holiday calendars.

Where this expression works

• Linux and macOS crontab: as written; times follow the system timezone.
• Kubernetes CronJob: the same five fields; UTC unless spec.timeZone is set.
• GitHub Actions: the same syntax in UTC, minimum interval five minutes, no @ shortcuts.
• AWS EventBridge: a different six-field syntax; do not paste this expression unchanged.
