Day of Month + Day of Week Interaction
In standard cron, if both Day of Month and Day of Week are specified (not *), the job runs when either condition is met (OR logic). If only one is specified, only that field is checked. For example, 0 9 15 * 1 runs at 9 AM on the 15th of every month and every Monday.
