C# Class System.Globalization.CCJulianCalendar

A class encapsulating the functions of the Julian calendar as static methods.

The algorithms don't support a year 0. Years before Common Era (B.C.E. or B.C.) are negative and years of Common Era (C.E. or A.D.) are positive.

This class is not compatible to T:System.Globalization.JulianCalendar.
