I wrote a SQL function years ago to build a dynamic holiday table as a table function. The link is below:

Hope it helps...

You can access the table function (or your own holiday table) to determine number of holidays via a SQL statement like below

SELECT count(*) FROM holiday_date(2013)
WHERE holiday_date BETWEEN @fromDate AND @toDate

then add the count to the returned date using dateAdd().

If you might have holidays that fall on a weekend, add the following to the WHERE clause

   AND DatePart(dw, Holiday_date) != 1) and (DatePart(dw, holiday_date) != 7)
