How to find number of days between two given dates

Hi Gurus,

I have requirement to calculate number of days between two given days( Start date and End Date). I know Daysbetween function will do this. But the issue is when we are finding the difference we need to consider holidays.

For Ex. Jan 14 th is friday that is my start date and he completed his work on Jan 17(End date) that is Monday, so three days between 14 and 17, but that is not correct in terms of business since i need to ignore holidays between these two dates, so number of days between these two dates are 1 not 3.

Any ideas!

Thanks,
