C# and Calendars

C# provides abstract class Calendar, which implements basic calendar operations, and different calendar implementations:

GregorianCalendar, HebrewCalendar, HijriCalendar, JapaneseCalendar, JulianCalendar, KoreanCalendar, TaiwanCalendar, and ThaiBuddhistCalendar.

Sample of calendars usage:

using System;
using System.Globalization;

namespace CalendarSamples
{
 class Program
 {
     static void Main()
     {
         DateTime now = DateTime.Now;

         HebrewCalendar hebrewCalendar = new HebrewCalendar();
         String hebrewDate = String.Format("{0} {1} {2}",
             hebrewCalendar.GetDayOfMonth(now),
             hebrewCalendar.GetMonth(now),
             hebrewCalendar.GetYear(now));

         GregorianCalendar gregorianCalendar = new GregorianCalendar();
         String gregorianDate = String.Format("{0} {1} {2}",
             gregorianCalendar.GetDayOfMonth(now),
             gregorianCalendar.GetMonth(now),
             gregorianCalendar.GetYear(now));

         JulianCalendar julianCalendar = new JulianCalendar();
         String julianCDate = String.Format("{0} {1} {2}",
             julianCalendar.GetDayOfMonth(now),
             julianCalendar.GetMonth(now),
             julianCalendar.GetYear(now));

         Console.WriteLine("date: " + now);
         Console.WriteLine("hebrew date: " + hebrewDate);
         Console.WriteLine("gregorianCalendar date: " + gregorianDate);
         Console.WriteLine("julianCalendar date: " + julianCDate);
     }
 }
}
