A simple small formula for finding working days between two days (i.e. days excluding holidays and weekends.)

Steps followed:

1) Holidays are populated from a view named holidays;

2) date range arrived by exploding;

3) Holidays in the date range replaced with null value , resulting in all days in the range except the holidays;

4) Next step is to remove all weekends ;using @weekdays and removing 1's and 7's(sun=1 and sat=7)
*FROM and TO are two date fields*

FIELD holidays:=@Dbcolumn("":"NoCache";"";"Holidays";1); FIELD dateRange:=@Explode(@TextToTime(@Text(FROM)+"-"+@Text(TO))); FIELD wkgDaysWithWE:=@Weekday(@TextToTime(@Trim(@Replace(dateRange;holidays;NULL)))); @Elements(@Trim(@Replace(@Text(wkgDaysWithWE);"1":"7";NULL))); OR use this one liner ;-) @Elements(@Trim(@Replace(@Text(@Weekday(@TextToTime(@Trim(@Replace(date
Range;holidays;NULL)))));"1":"7";NULL)));
