RecurrenceDay
Specifies the days of the week. Members might be combined using bitwise operations to specify multiple days.
The constants in the RecurrenceDay enumeration might be combined with bitwise operations to represent any combination of days. It is designed to be used in conjunction with the RecurrencePattern class to filter the days of the week for which the recurrence pattern applies.

public enum RecurrenceDayExample:
Consider the following example that demonstrates the basic usage pattern of RecurrenceDay. The most common operators used for manipulating bit fields are:
- Bitwise OR: Turns a flag on.
- Bitwise XOR: Toggles a flag.
- Bitwise AND: Checks if a flag is turned on.
- Bitwise NOT: Turns a flag off.
