Hi ,

 

Below given code should help u in calculating number of working days.Just to let u know it is not my code.

 

 

private Integer getDiffBusinessDays(Date startdt, Date enddt) {
 Date tempdate = null;
 if (startdt > enddt) {
 tempdate = enddt;
 enddt = startdt;
 startdt = tempdate;
 }
Integer i = Math.mod((date.newinstance(1985, 6, 24)).daysBetween(startdt),7); // 24/6/85 was a monday
Map<Integer, Map<Integer, Integer>> m = new Map<Integer, Map<Integer, Integer>> {
0 => new Map<Integer, Integer> { 1 => 2 , 2 => 3 , 3 => 4 , 4 => 5 , 5 => 5 , 6 => 5 },
1 => new Map<Integer, Integer> { 1 => 2 , 2 => 3 , 3 => 4 , 4 => 4 , 5 => 4 , 6 => 5 },
2 => new Map<Integer, Integer> { 1 => 2 , 2 => 3 , 3 => 3 , 4 => 3 , 5 => 4 , 6 => 5 },
3 => new Map<Integer, Integer> { 1 => 2 , 2 => 2 , 3 => 2 , 4 => 3 , 5 => 4 , 6 => 5 },
4 => new Map<Integer, Integer> { 1 => 1 , 2 => 1 , 3 => 2 , 4 => 3 , 5 => 4 , 6 => 5 },
5 => new Map<Integer, Integer> { 1 => 0 , 2 => 1 , 3 => 2 , 4 => 3 , 5 => 4 , 6 => 5 },
6 => new Map<Integer, Integer> { 1 => 1 , 2 => 2 , 3 => 3 , 4 => 4 , 5 => 5 , 6 => 5 }
};
Integer i2 = Math.mod((startdt.daysBetween(enddt)),7);
Integer i3 = (m.get(i)).get(i2);
if (i2 == null || i2 < 1 || i2 > 6) {
if (i >= 0 && i <= 4) { i3 = 1; }
else  { i3 = 0; }
}
i3 = i3 + 5 * (Math.floor( ((Decimal) startdt.daysBetween(enddt)).divide(7,4))).intValue();
if (tempdate != null) i3 *= -1; // negative number of days
return i3;
    }

Hi Priya,

 

You can use this formula field to calculate busineesdays between the staring date and ending date,

 

if this answer is correct to your question please mark it as correct answer,it will be help to some one

 

 

5*FLOOR((
  CASE(MOD(SSD__c-DATE(1900,1,7)

@Surprise: I had to get rid of the check if tempDate == Null part to get it right. Because for me a difference in business days can not be negative... ;)
