Days Between Dates

Days Between Dates

Two formulas that I often use in views to calculate the days between two dates. One formula is used for calendar days. The other excludes weekends.

 REM "Calendar Days Between 2 Dates"; EndDate := @Today; StartDate := AnyDateField; diffDays := (EndDate - StartDate)/86400 + 0; @If(@IsError(diffDays); 0; diffDays) REM "Days Between 2 Dates Excluding Weekends"; EndDate := @Today; StartDate := AnyDateField; diffDays := (EndDate - StartDate)/86400 + 0; strtDay := @Modulo(@Weekday(StartDate); 7); endDay := @Modulo(@Weekday(EndDate); 7); result := @Integer((diffDays - endDay + strtDay - 8)*5/7 - @Max(-2; -strtDay) - @Min(1; endDay) + 5 - strtDay + endDay); @If(@IsError(result); 0; result)
