The program membership date is set when a record is added to a program by changing the program status. You can see the program membership date when you click on the members tab in a program. A friendly reminder that the column needs to be on your view.

I recommend not changing the program status to ‘Not in Program’ to remove members from a program if you need to move the program to another workspace. When you use this status it will clear the membership date. There is no method to reset the membership date back to the original membership date. If the program was the one which acquired the record, removing a record from a program will also clear the acquisition program and acquisition date which will mess up attribution reporting. The best option when moving a program to another workspace is to use a temporary lead partition to remove and then re-add them members.
