Hi Pradeep,
You can define as;
Mon - Sat { 9:00 am - 9:00 pm }
4/15/2017
4/25/2017
5/13/2017
5/27/2017
.
.
Exclusion dates may be hard to define manually. You can update this field via PAM by use date control and you can automatically update this field by a schedule job
May be there is a simple way to define, This is the first one that comes to mind
Best regards
Turker
