First, you need to Create a formula field that will name the Day of the Week for the Task/Activity Due Date


Name it: Due Date - Day of Week

Select Formula, then Text


Insert the following formula:


CASE(MOD(  ActivityDate - DATE(1900, 1, 7), 7),
0, "Sunday", 1, "Monday", 2, "Tuesday", 3,
"Wednesday", 4, "Thursday", 5, "Friday", 6,
"Saturday","Error")



Once you've accomplished this, you will need to create 2 workflow rules on the Task Object


Workflow Rule Criteria 1

  • Due Date = Sunday


Evaluation Criteria: Option 2


Workflow Action Type = Filed Update

  1. Update Activity Date to  Activity Date + 1

-------------------------------


Workflow Rule Criteria 2:

  • Due Date = Saturday

Evaluation Criteria: Option 2


Workflow Action Type = Field Update

  • Set Activity Date to Activity Date + 2 Days
