Hello,
After seeing this following post and in order to not reopen it, I tried the function explained at the bottom but it returns sometimes suspicious values.
Remind, here's the function :
let
// calculates a duration between two timestamps in working hours
fnDurationWorkingHours = (StartDateTime as datetime, EndDateTime as datetime) as duration =>
let
// start and end date
StartDate = Date.From(StartDateTime),
EndDate = Date.From(EndDateTime),
// start and end time
StartTime = Time.From(StartDateTime),
EndTime = Time.From(EndDateTime),
// end of the shift on the first day and start of the shift on the last day
ShiftEndOnStartDate = #time(17, 0, 0),
ShiftStartOnEndDate = #time(8, 0, 0),
// working days are from Mon=0 to Fri=4
fnIsWorkingDay = (dt as date) as logical => Date.DayOfWeek(dt, Day.Monday) < 5,
// generate whole days between StartDateTime and EndDateTime
DaysBetween = List.Generate(
() => Date.AddDays(StartDate, 1),
each _ < EndDate,
each Date.AddDays(_, 1)
),
// select only working days
WorkingDaysBetween = List.Select(DaysBetween, fnIsWorkingDay),
// get minimum of two times
fnMin = (first as time, second as time) as time =>
if first > second then second else first,
// get maximum of two times
fnMax = (first as time, second as time) as time =>
if first > second then first else second,
// duration on the first day
StartDateWorkingHours =
if not fnIsWorkingDay(StartDate) then
#duration(0, 0, 0, 0)
else if ShiftEndOnStartDate < StartTime then
#duration(0, 0, 0, 0)
else
ShiftEndOnStartDate - fnMax(StartTime, ShiftStartOnEndDate),
// duration on the days between
WorkingHoursBetween = #duration(0, List.Count(WorkingDaysBetween) * 9, 0, 0),
// duration on the last day
EndDateWorkingHours =
if not fnIsWorkingDay(EndDate) then
#duration(0, 0, 0, 0)
else if EndTime < ShiftStartOnEndDate then
#duration(0, 0, 0, 0)
else
fnMin(EndTime, ShiftEndOnStartDate) - ShiftStartOnEndDate,
// sum it up
Result =
if StartDateTime > EndDateTime then
#duration(0, 0, 0, 0)
else if StartDate = EndDate and not fnIsWorkingDay(StartDate) then
#duration(0, 0, 0, 0)
else if StartDate = EndDate then
fnMin(EndTime, ShiftEndOnStartDate) - fnMax(StartTime, ShiftStartOnEndDate)
else
StartDateWorkingHours +
WorkingHoursBetween +
EndDateWorkingHours
in
ResultBut for example, when I have in start and end time these
There's no 6 days and 20h betweend 19/09/2022 and 13/10/2022, even if we exclude weekends.
Some other examples :
Could you help me please ?
Thank you!

Hello,
I tried your solution but it seems to have problems in it :
Some results are wrong (between 3 and 17, there's not only 3 days 😞 )
Check this. Ignore first 4 rows (I've added them just for test purpose).
You can edit shiftStart and shiftEnd in Helper step.
EDIT: I've added option where you can decide whether you want to include or exclude weekends:

I removed ChangedType because in function, it allows only 3 or 4 parameter. I let Helper but I got this now :
I refreshed the post, but in your function, I still see only 4 parameters :
