Cron Weekdays at 9 AM and 5 PM

The cron expression 0 9,17 * * 1-5 fires twice per weekday — at 9:00 AM and 5:00 PM, Monday through Friday. The list 9,17 in the hour field targets both times, and 1-5 limits to weekdays.

This start-and-end-of-day schedule is perfect for bookend tasks: morning data preparation and evening wrap-up. Common uses include generating opening and closing reports, syncing data at the start and end of business, running pre-market and post-market financial jobs, and sending morning briefings and evening summaries.

The schedule produces 10 executions per week (2 per day × 5 weekdays). To add a midday run, use 0 9,12,17 * * 1-5 for three times daily on weekdays.
