The examples in this chapter are based on the following assumptions:

• The current month is December 2001.
• Working days are defined in the WORKDAYS calendar that contains the following working days (indicated by Y) for December 2001:

  --S-------------S-------------S-------------S-------------S--

  1 2 3 4 5 6 7 8 9 + 1 2 3 4 5 6 7 8 9 + 1 2 3 4 5 6 7 8 9 + 1

      Y Y Y Y Y     Y Y Y Y Y     Y Y Y Y Y     Y   Y Y Y     Y

• The PERIDAYS periodic calendar contains the following periodic definition for December 2001. These examples assume that all other days of this calendar are blank.

  --S-------------S-------------S-------------S-------------S--

  1 2 3 4 5 6 7 8 9 + 1 2 3 4 5 6 7 8 9 + 1 2 3 4 5 6 7 8 9 + 1

      B C A A B     B C A A B     B C A A B     B C A A B     B

• Start of the week is defined as Monday. Weeks start on the following dates in December 2001: 3rd, 10th, 17th, 24th, and 31st.
