VB.NET Core Classes in a Nutshell

Name

GregorianCalendar

Synopsis

This class implements the standard Western calendar, and also the default culture-invariant calendar. It defines two eras (B.C./B.C.E. and A.D./C.E.), 12 months per year. A leap year occurs every four years except for years divisible by 100. However, years divisible by 400 are leap years. Only the current era (A.D./C.E.) is recognized by .NET’s implementation of the Gregorian calendar.
