Calculating the number of Business Days between two dates

by  Reebo99  Posted    (Edited  )
Use the following formula, replacing the items in Bold with your start/end date and the items in Italics with your holidays........

WhilePrintingRecords;
[color green]//Set the values of Start Date and End Date[/green]
DateVar StartDate := Date(2003,01,01);
DateVar EndDate := Date(2003,12,31);

[color green]//Find out the difference in days and subtract the weekends[/green]
NumberVar DaysDiff := DateDiff("d",StartDate,EndDate) -
DateDiff("ww",StartDate,EndDate,crsaturday) -
DateDiff("ww",StartDate,EndDate,crsunday);

[color green]//Create an array of Holiday dates[/green]
Local DateVar Array Holidays := MakeArray(
Date(2003,01,01),
Date(2003,01,02),
Date(2003,12,25),
Date(2003,12,26),
Date(2003,07,07)
);

[color green]//Loop through the array checking if each holiday is within the dates[/green]
Numbervar Counter := 0;
While UBound(Holidays) <> Counter do
(Counter := Counter + 1;
if Not(dayofweek(Holidays[Counter]) in [1,7]) and
Holidays[Counter] in StartDate to EndDate then DaysDiff := DaysDiff -1;);

[color green]//Display result to 0 decimal places and no thousand separator[/green]
totext(DaysDiff,0,"");
