Hey @jarous
Take a look here
In Summary, you need to use a “Non-working days” calendar COMBINED with a cron expression.
Cron Expression:
0 0 10,15 3,4,5,6,7,8,9,10 * ? *
Description of cron:
At 10:00 AM and 03:00 PM, on day 3, 4, 5, 6, 7, 8, 9, and 10 of the month
Non-Working Days Calendar
Then just create the calendar to exclude all Saturday and Sundays.
Let me know if have any further questions. Happy to help where I can
Cheers
Steve
