how to calculate hours between 2 dates but excluding weekends ?

Looking for way&logic to calculate hours between 2 dates (Ticket.date_opened
and Ticket.solved_date) but excluding weekends ?
This function calculates hours only
DATEDIFF(hour, Ticket.date_opened, Ticket.solved_date).
Thanks!No easy way! I have to do something like this myself next week.
You have to decide whether this is going to be done in SQL or VB. I'd
suggest VB will be the easiest to code and depending on the volumes of
data involved may be best.
So assuming VB, I'd suggest the datediff function you have, then work
out how many weekends in the daterange, you can use the weekday
function to tell what day you are starting on, subtract the number of
weekends * 48 and you'll be someway towards it.

Looking for way&logic to calculate hours between 2 dates (Ticket.date_opened
and Ticket.solved_date) but excluding weekends ?
This function calculates hours only
DATEDIFF(hour, Ticket.date_opened, Ticket.solved_date).
Thanks!You need to create a custom VB.NET function that takes the two dates, sth
like:
Dim DaysPassed As Integer = DateDiff(DateInterval.Day, d1, d2)
Dim SaturdaysPassed As Integer = DateDiff(DateInterval.WeekOfYear,
d1, d2, FirstDayOfWeek.Sunday) 'Using Sunday because it means that the
Saturday has actually fully passed by
Dim SundaysPassed As Integer = DateDiff(DateInterval.WeekOfYear, d1,
d2, FirstDayOfWeek.Monday)
Dim HoursPassed As Integer = (DaysPassed - SaturdaysPassed -
SundaysPassed) * 24

How to pass date_opened and last_updated values?
Should it be report fields - Fields!date_opened.Value,
Fields!last_updated.Value?

assembly. From the field that needs to be validated, you pass the date
fields as input parameters. You may find the beginning of this article

How to calculate hours between 2 dates but excluding weekends

Looking for way&logic to calculate hours between 2 dates (Ticket.date_opened and Ticket.solved_date) but excluding weekends ?
This function calculates hours only
DATEDIFF(hour, Ticket.date_opened, Ticket.solved_date).

Thanks!I suggest you create a function to calculate the number of weekdays between 2 dates (excluding the weekends using the datepart(dw,@.date)-function) and multiplying this by 24...

or alternativly,
calculating the weekend-days, multiplying this by 24 and subtract the datediff-result with this value
this will only be correct if you use dates which are no weekenddays themselfs ofcourse...
