	Name	Description
	MaxValue	The maximum value of a period which is "(9999-12-30, 9999-12-31)".
	MinValue	The minimum value of a period which is "(0001-01-01, 0001-01-02)".
	Null	Gets a Null TdPeriodDate instance.

	Name	Description
	Begin	Gets the beginning bound of the period.
	End	Gets the ending bound of the period.
	IsNull	Gets boolean value that indicates whether this TdPeriodDate instance is TdPeriodDate.Null.
	Last	Gets the last time element of the period.
	Value	Gets the ANSI string representation of the this instance of the period.

	Name	Description
	Add	Overloaded.
	Compare	Compares two instances of TdPeriodDate structures and returns a value indicating whether left is greater than, less than or equal to right.
	CompareTo	Overloaded. Compares this instance to the supplied object and returns whether it is less than, equal or greater than the supplied object.
	Contains	Indicates whether the TdDate value is contained in this instance of TdPeriodDate.
	Equals	Overloaded. Returns a Boolean indicating whether two instances of TdPeriodDate are equal.
	GetHashCode	Returns the hash code for this instance.
	GetType	Gets the System.Type of the current instance. (Inherited from object)
	GetXmlSchema	Specifies the XML Qualified name for TdPeriodDate XML type mapping.
	GreaterThan	Compares two TdPeriodDate structures to determine whether the left operand is greater than the right operand.
	GreaterThanOrEqual	Compares two TdPeriodDate structures to determine whether the left operand is greater than or equal to the right operand.
	Intersect	The intersection between the left and right operands is calculated.
	IntervalDayToSecond	Calculates the number of days in the period and returns the result in a TdIntervalDayToSecond structure.
	IntervalTimeSpan	Calculates the number of days in the period and returns the result in a System.TimeSpan structure.
	IntervalYearToMonth	Calculates the number of days in the period and returns the result in a TdIntervalYearToMonth structure.
	LeftDiff	The period whose beginning and ending bounds are defined as the beginning bound of the left operand and the beginning bound of the right operand when the operands overlap.
	LessThan	Compares two TdPeriodDate structures to determine whether the left operand is less than the right operand.
	LessThanOrEqual	Compares two TdPeriodDate structures to determine whether the left operand is less than or equal to the right operand.
	Meets	Overloaded. Determines whether a period or TdPeriodDate meets this instance of TdPeriodDate.
	Normalize	A TdPeriodDate that contains a period that encompasses both periods of the left and right operands. The beginning bound is defined as the minimum of left and right beginning bounds, and the ending bound is defined as the maximum of the left and right ending bounds. The operands must either meet or overlap.
	NotEquals	Compares two TdPeriodDate structures to determine whether the left operand is not equal to the right operand.
	Parse	The specified string is converted into an equivalent TdPeriodDate.
	Precedes	Overloaded. Determines whether a period or TdDate precedes this instance of TdDate.
	RightDiff	The period that contains the portion from the ending bound of the left operand to the ending bound of the right when the operands overlap.
	Subtract	Overloaded.
	Succeeds	Overloaded. Determines whether a period or TdDate succeeds this instance of TdDate.
	ToString	Overloaded. Returns the string representation of a period.
	TryParse	The specified string is converted into an equivalent TdPeriodDate.

Addition	Overloaded. Adds a Timespan to a period.
Equality	Compares two TdPeriodDate structures to determine whether the left operand is equal to the right operand.
Explicit Type Conversion	Overloaded.
Greater Than	Compares two TdPeriodDate structures to determine whether the left is greater than the right operand.
Greater Than or Equal	Compares two TdPeriodDate structures to determine whether the left is greater than or equal to the right operand.
Inequality	Compares two TdPeriodDate structures to determine whether the left operand is not equal to the right operand.
Less Than	Compares two TdPeriodDate structures to determine whether the left is less than the right operand.
Less Than or Equal	Compares two TdPeriodDate structures to determine whether the left is less than or equal to the right operand.
Subtraction	Overloaded.
