This which helps to find number of working days between two dates in Mysql. There is no specific or inbuilt function in mysql, For that we need to use the SQL query as below.
[sql]
SELECT 5 * ((DATEDIFF(@end_date, @start_date) ) DIV 7) + MID(‘0123455501234445012333450122234501101234000123450’, 7 * WEEKDAY(@start_date) + WEEKDAY(@end_date) + 1, 1)
[/sql]
