# Find # of hours between 2 dates, excluding weekends, in C#

I need to calculate the number of hours a ticket has been, or was open by subtracting 2 dates. All weekend hours need to be excluded. (All in C#) Can someone assist?

Sure, so far I only display the flat difference in hours (see snippet). I need to adapt it to exclude weekends.

Super quick, super dirty.  This calculates days but you could easily modify it to do hours.
I can modify it if you need.
``````            //Todays Date
DateTime dt2 = DateTime.Now;

//Previous Date
DateTime dt = DateTime.Parse("10/15/2008");

//TimeSpan Between Dates
TimeSpan dt3 = dt2 - dt;

//Count of days not including weekends
int dayCount = 0;

//1 day timespan
TimeSpan ts = new TimeSpan(1, 0, 0, 0);

for (int i = 1; i < dt3.Days+1; i++)
{
//Today - TimeSpan(1 Day)
dt2 = dt2.Subtract(ts);

if (dt2.DayOfWeek != DayOfWeek.Saturday && dt2.DayOfWeek != DayOfWeek.Sunday)
{
dayCount++;
}

}

Yeah I definitely need hours, as in, if someone starts a ticket on Friday and happens to close it on a Saturday, none of the hours from Saturday count, and only the partial day (in hours) for Friday will count.
I'm not seeing a straight-forward way to do this above, would we convert the day count to a decimal and multiply by 24 at the end?

I didn't have a chance to fully debug this but it looks like it works.
``````DateTime dt2 = DateTime.Now;

DateTime dt = DateTime.Parse("10/15/2008");

TimeSpan dt3 = dt2 - dt;

int hourCount = 0;
int totalHours = 0;

totalHours += dt3.Days * 24;
totalHours += dt3.Hours;

//1 hour timespan
TimeSpan hour = new TimeSpan(1, 0, 0);

for (int i = 1; i < totalHours+1; i++)
{
dt2 = dt2.Subtract(hour);

if (dt2.DayOfWeek != DayOfWeek.Saturday && dt2.DayOfWeek != DayOfWeek.Sunday)
{
hourCount++;
}
}
``````
