I have two dates and I want to calculate the number of days for each period.
local dcheck_in: = ctod ("17/05/2020")
local dCheck_out: = ctod ("17/06/2020")
if I do the operation
dCheck_out-dcheck_in
i get 31 days
in the calculation function for the periods they inexplicably become 32 and I have not yet understood why ( see column number 5)
I have tried with other dates and sometimes the calculation is right and sometimes it is wrong
to calculate the days I use this function
- Code: Select all Expand view RUN
- Function GetDayofPeriod(dDateFrom,dDateTo,aListini)
Local d, n
//reset days
For n=1 to len(aListini)
aListIni[n][5]:=0
next
For d = dDateFrom to dDateTo
For n=1 to len(aListini)
IF d >= aListini[n][1] .and. d <= aListini[n][2]
alistini[n][5] += 1
endif
Next
Next
return alistini
if you want to try it, I have prepared a small test
Thanks in advance for the help I hope I can get from U
