Question

Date functions
I have 2 properties StartDate and ExpectedDate of type Date&Time.If I give any date to the StartDate property then the ExpectedDate should be coming Monday 9AM.
For Example if StartDate=02/01/2019 4:50PM then ExpectedDate=07/01/2019 9AM(which is coming Monday)
StartDate=10/01/2019 3:45 PM then ExpectedDate=14/01/2019 9AM(which is coming Monday)
Please help me to solve this issue.
