14 hours I think I might be wrong It's 48 hours from 3 PM Friday until 3 PM Sunday, then it's another 9 hours until midnight and another 8 hours until 8 AM Monday. (48 + 9 + 8) hours = 65 hours.
Friday 11pm to Monday 11pm is exactly 3 days or 72 hours.
That's a total of 30 hours.

(84+168k) hours where k is an integer.

The answer depends on whether you start from 0:01 am on or 11:59 am on Friday to 0:01 am on or 11:59 am on Monday. The answer can range between just over 60 hours to just under 84 hours!
