As the question was asked on a Sunday, the answer is 48 hours.
From Saturday AM to Tuesday PM is a total of 58 hours. This is calculated by counting the full days between Saturday morning and Tuesday afternoon, which includes two full days (48 hours) plus the hours from Saturday morning to the end of Saturday (24 hours) and from Sunday to Tuesday PM (another 24 hours). Thus, it sums up to 58 hours.
There are 48 hours from midday on Friday to midday on Sunday.
72 hours from 9 PM Sunday night would be 9 PM Wednesday night. To break it down, 24 hours after Sunday night is 9 PM Monday, 48 hours is 9 PM Tuesday, and 72 hours brings you to 9 PM Wednesday.
