VB.NET Core Classes in a Nutshell

Name

Calendar

Synopsis

This MustInherit class determines the division and measurement of time in units, such as day, months, years, and eras. It is a MustInherit 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.
