How it will work when business day is Holiday?.How above cron expression works? – user1726550 Oct 21 '12 at 12:19
@user1726550: `W` is just a shorthand for week day (Mon - Fri), national holidays vary in every country and Quartz can't keep track of all of them. As for you other questions - try with simple `Calendar` class, it should help you a lot. Or better, go for Joda Time. – Tomasz Nurkiewicz Oct 21 '12 at 12:41
