To change the list of non-working business dates

Typically, you define the list of holidays and other non-working dates at the beginning of the calendar year, before marketing calendar details are set. However, you may need to change the set of non-working days after dates for tasks, projects, and programs have already been set. In this case, the process for changing the list of non-working business days is as follows.

1.	Make any changes to the list of non-working business days.

2.	If your changes affect any projects or tasks, you should use the Non-working Business Dates summary page to notify affected project owners.
