Calculate working hours between two dates

[naomi_j]

I'm trying to calculate the number of working hours/minutes between two dates (ie. excluding non-working hours and weekends).  

This is the basic format - and I'm trying to find out how long it takes for an issue to get resolved, in working hours/minutes.  Can anyone help, please?

I found the solution in this post really clear and helpful: https://addendanalytics.com/calculate-working-hours-in-power-bi/

Hi,

Looking at calculate minutes between a ticket was created and closed.

The measure needs to consider the following:

- Should ignore public holidays (Have a table called public holidays in which the date column has the days I have as public holidays)

- Should consider Mon to Friday

- Business Hours 7 am to 5 pm

- If completed is greater than created then should take it as 0

Step created at AEDT           Step Completed at AEDT

15/6/21 11:32:24 am             16/6/21 2:22:46 pm

Any help will be appreciated

@Greg_Deckler - I tried your net workdays option and it worked (thankfully no negative numbers output)!  Thanks!  

I changed the output to hours, which works better for me - although this seems to round off rather than offering part hours.  Do you know if there's a way to have the output in part-hours (eg. 1.25 for 1hr12mins instead of 1)?

[Greg_Deckler]

@naomi_j - Not entirely certain exactly what your code is but perhaps try increasing the number of decimals?

[naomi_j]

@Greg_Deckler see code below.  I tried to increase the number of decimals, but this doesn't work after the calculation is complete (.00 for all values).  

hoursNetworkDuration =

// Get the start and end dates

VAR __dateStart = Master_Appended[Created].[Date]

VAR __dateEnd = Master_Appended[ResolvedNoBlanks].[Date]

// Calculate the Net Work Days between the start and end dates

VAR __NetWorkDays = COUNTX(FILTER(ADDCOLUMNS(CALENDAR(__dateStart,__dateEnd),"WeekDay",WEEKDAY([Date],2)),[WeekDay]<6),[Date])

// Set this to the start of the work day (8:00 AM)

VAR __startTime = TIME(8,0,0)

// Set this variable to the end of the work day (5:00 PM)

VAR __endTime = TIME(17,0,0)

// Calculate the duration of a full day, in this case in minutes

VAR __fullDayhours = DATEDIFF(__startTime,__endTime,HOUR)

// 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 * __fullDayhours

// 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,HOUR)

// 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,HOUR)

// 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,HOUR),__fullDaysDuration + __startDayDuration + __endDayDuration)

[Greg_Deckler]

I think if you do something like:

IF(__NetWorkDays=1,DATEDIFF(__dateStart,__dateEnd,MINUTE) / DATEDIFF(__dateStart,__dateEnd,HOUR) / 60,__fullDaysDuration + __startDayDuration + __endDayDuration)

[naomi_j]

😞 still gives me whole hour output (.00).  

[naomi_j]

Thanks Greg - it seems the Net Work Days option should be close to what I want.  Although I will have the same issue as the other user who commented in the thread (start and finish times potentially occurring out of work hours).  Was there a solution for avoiding the negative numbers?

Thanks again!

@naomi_j 

You may calculate working hours/minutes since Mon, Feb 24, 2020.

DIFF ( <Base>, <Resolved> ) - DIFF ( <Base>, <Created> )

[naomi_j]

Thanks for your response, @v-chuncz-msft.  I've not seen this option - are there any articles to explain the function?  

What would be the <Base> value here?
