To count business days between two dates (''startdate'' and ''enddate''), the following code can be used in a [[Custom Field Type: Special – Browser Script|Special Browser script]] field that will populate a [[Custom Field Type: Special – Calculated Value|Calculated Value Custom Field]] with the number of business days between two given dates.
In the [[Custom Field Type: Special – Browser Script|Special Browser script]] field you define the function that calculates the difference:
<pre>
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;
}
</pre>
In '''Expression''' section of the [[Custom Field Type: Special – Calculated Value|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 [[Custom Field Type: Special – Calculated Value|Calculated Value Custom Field]].
