Every 2 hours on weekdays
0 */2 * * 1-5Fires at the top of every even-hour during weekdays — twelve times per workday.
Why this pattern
0 */2 * * 1-5 fires at 00:00, 02:00, 04:00, ..., 22:00 on every weekday. Twelve fires per workday, sixty per workweek. Useful for warm-cache jobs, slow-moving syncs, and recurring digest emails that need more frequency than "once a day" but should not flood the destination.
Variations
- Every 3 hours weekdays:
0 */3 * * 1-5 - Every 2 hours, business window only:
0 8-18/2 * * 1-5 - Every 2 hours including weekends:

Platform notes
*/2 in the hour field is well-supported across all dialects; the only watchout is AWS EventBridge, which requires a 6-field expression with ? in either day-of-month or day-of-week. Use the dialect picker to switch and see the auto-corrected form.
