title: Determine the amount of days between events excluding weekends in python
body: <p>I am trying to determine the amount of days between updates on a ticket in zendesk, excluding weekends. I have been able to determine the difference between updates, but it doesnt take into account weekends. I want to determine if the user has updated their ticket within 3 days, excluding weekends, then close the ticket if it has been over 3 days. This is what I have:</p>
  <pre><code>updated_time = updated_time[0:10:1]
  time_now = str(datetime.datetime.now())
  time_now = time_now[0:10:1]
  updated_time = dateutil.parser.parse(updated_time)
  time_now = dateutil.parser.parse(time_now)
  date_to_close = datetime.timedelta(days=3)
  please_close = time_now - updated_time
  </code></pre>
  <p>My problem is because it doesnt distinguish between weekdays and weekends, it will automatically close the ticket on Monday if no one has responded over the weekend, which I would not like to count. I've been looking at the isoweekday() but its not really giving me what I need. I was thinking about trying to assign the ticket to a variable and assigning it a number, then increase that number by days without an update, that way it would not count the specific date but rather the number of days in between, but not sure how to do this or if it would even work.</p>
  <p>Does anyone have an idea how to count the difference between days while excluding weekends? Is this possible?</p>
