Counting Business Days between Two Dates
From SmartWiki
To count business days between two dates (startdate and enddate), the following code can be used in a Special Browser script field that will populate a Calculated Value Custom Field with the number of business days between two given dates.
In the Special Browser script field you define the function that calculates the difference:
function bus_date_diff()
{
var frm=document.forms[0];
var formatdate="@dateformat@";
var start=ConvertDateStr(frm.startdate.value,formatdate);
var end=ConvertDateStr(frm.enddate.value,formatdate);
var diff=datediff(start,end, "D");
var i=0;
var busdays=0;
for(i=0;i<diff;i++)
{
var cdate=dateadd(start,'D',i);
if(!isHoliday(cdate))
busdays++;
}
return busdays;
}
In Expression section of the Calculated Value Custom Field you would call the function:
bus_date_diff()
Note: The function definition can be changed to accept parameters (fields containing dates) that are passed at the time of calling the function from any Calculated Value Custom Field.
