## Net Work Duration

Similar to Net Work Days, Net Work Duration calculates the total duration between two date/time columns taking into account non-working days (weekends) as well as the start and end times for a work day. This version calculates duration in minutes, although this can be easily changed.

`mNetWorkDuration = // Get the start and end datesVAR __dateStart = MAX([Date_Start])VAR __dateEnd = MAX([Date_End])// Calculate the Net Work Days between the start and end datesVAR __NetWorkDays = COUNTX(FILTER(ADDCOLUMNS(CALENDAR(__dateStart,__dateEnd),"WeekDay",WEEKDAY([Date],2)),[WeekDay]<6),[Date])// Set this to the start of the work day (7:30 AM)VAR __startTime = TIME(7,30,0)// Set this variable to the end of the work day (6:00 PM)VAR __endTime = TIME(18,0,0)// Calculate the duration of a full day, in this case in minutesVAR __fullDayMinutes = DATEDIFF(__startTime,__endTime,MINUTE)// Calculate teh number of full days, this accounts for the possibility that tickets start and end on the same dayVAR __fullDays = IF(__NetWorkDays < 2,0,__NetWorkDays-2)// Calculate the total duration of all full days.VAR __fullDaysDuration = __fullDays * __fullDayMinutes // Calculate the start time of the current recordVAR __startDayTime = TIME(HOUR(__dateStart),MINUTE(__dateStart),SECOND(__dateStart))// Caclulate the duration of time for the first dayVAR __startDayDuration = DATEDIFF(__startDayTime,__endTime,MINUTE)// Calculate the end time of the current recordVAR __endDayTime = TIME(HOUR(__dateEnd),MINUTE(__dateEnd),SECOND(__dateEnd))// Calculate the duration of time for the last dayVAR __endDayDuration = DATEDIFF(__startTime,__endDayTime,MINUTE)// The total duration is the duration of all full days plus the durations of time for the first and last daysRETURN  IF(__NetWorkDays=1,DATEDIFF(__dateStart,__dateEnd,MINUTE),__fullDaysDuration + __startDayDuration + __endDayDuration)`

Hi,

I was trying to use this measure, but if we have dates that are outside working hours, the values are not correct ( see attachment).

So, if the time is outside of the work hours, how would you want the work hours to be calculated, do you want it to ignore any non work hour time?

If this works for you, I will update the Quick Measure:

```mNetWorkDuration =
// Get the start and end dates
VAR __dateStart = MAX([Date_Start])
VAR __dateEnd = MAX([Date_End])
// Calculate the Net Work Days between the start and end dates
// Set this to the start of the work day (7:30 AM)
VAR __startTime = TIME(7,30,0)
// Set this variable to the end of the work day (6:00 PM)
VAR __endTime = TIME(18,0,0)
// Calculate the duration of a full day, in this case in minutes
VAR __fullDayMinutes = DATEDIFF(__startTime,__endTime,MINUTE)
// Calculate teh number of full days, this accounts for the possibility that tickets start and end on the same day
VAR __fullDays = IF(__NetWorkDays < 2,0,__NetWorkDays-2)
// Calculate the total duration of all full days.
VAR __fullDaysDuration = __fullDays * __fullDayMinutes
// Calculate the start time of the current record
VAR __startDayTime = TIME(HOUR(__dateStart),MINUTE(__dateStart),SECOND(__dateStart))
VAR __startDayTime1 = SWITCH(
TRUE(),
__startDayTime>__endTime,__endTime,
__startDayTime<__startTime && __startDayTime>TIME(0,0,0),__startTime,
__startDayTime
)
// Caclulate the duration of time for the first day
VAR __startDayDuration = DATEDIFF(__startDayTime1,__endTime,MINUTE)
// Calculate the end time of the current record
VAR __endDayTime = TIME(HOUR(__dateEnd),MINUTE(__dateEnd),SECOND(__dateEnd))
VAR __endDayTime1 = SWITCH(
TRUE(),
__endDayTime>__endTime,__endTime,
__startDayTime<__startTime && __startDayTime>TIME(0,0,0),__startTime,
__endDayTime
)
// Calculate the duration of time for the last day
VAR __endDayDuration = DATEDIFF(__startTime,__endDayTime1,MINUTE)
// The total duration is the duration of all full days plus the durations of time for the first and last days
RETURN
IF(__NetWorkDays=1,DATEDIFF(__dateStart,__dateEnd,MINUTE),__fullDaysDuration + __startDayDuration + __endDayDuration)```

## Re: Net Work Duration

Hi Greg,

Thank you very much for your help.
I still get negative values when both start/end time are outside working hours.

Date Start - 07-07-2018 21:27:00

Date End - 08-08-2018 00:05:00

I get -445

In this cases i was expecting to have 0 instead of negative values.

Beside that, how can i get an average of the mNetWorkDuration?

Hey Greg many thanks for your inputs, could you also consider holidays , based on another "holidays" table?

Thank you so much!
