abstract class

This abstract class determines the division and measurement of time in units, such as day, months, years, and eras. It is an abstract base class for culture-specific calendar implementations included in this namespace. Derived classes store the specific information about a calendar's eras, lengths of years and months, and the sometimes esoteric rules for calculating leap years . These properties get used by DateTimeFormatInfo to properly display a date and time string from a specific DateTime value.
