title: SQL Sever - Datediff, hours, but exclude Saturday/ Sundays
body: <p>I'm wondering how to calculate the "number of hours" between two timestamps (2016-02-24 17:30:00 and another, for instance) in SQL server- but excluding Saturday and Sunday's full 48 hour period, if crossed.</p>
  
  <p>This isn't quite the same as pure business hours, but sort of. The reason for this is long-winded and unnecessary.</p>
  
  <p>EDIT: I can also say that the end-date will always be during the week. So really ... the "start date" can simply be transmuted to Monday midnight, if on Sat/ Sun ... then maybe a function include the total week count...</p>
