Hourly during business hours in cron

Ranges are inclusive: 9-17 selects 09:00 through 17:00, nine runs a day. If 17:00 should be the last minute rather than the last run, use 9-16.

Replace the minute field with a step for more frequent checks inside the same window: */15 9-17 * * 1-5 runs every quarter hour and */5 9-17 * * 1-5 every five minutes, in both cases until 17:55.

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.
