Sometimes you may want to filter to include specific individual dates or entire date levels. This type of filter is called a Discrete Date Filter because you are defining discrete values instead of a range. Follow the steps below to create a discrete date filter.
Drag a date field from the Data window and drop it on
the Filters shelf.
In the Filter Field dialog box, select a date level or select Individual
dates and then click Next.
In the Filter dialog box, select the dates you want to include.
When finished, click OK.
