Based on the amount of articles out there relating to hebrew dating (and I don't mean a singles bar!) there's always confusion on how exactly to translate a date into its full hebrew representation. Here's a simple method that does this, based on information which is easily available via this article.

C#

/// <summary>
  /// Returns the Juwish formatted date
  /// </summary>
  /// <param name="anyDate">Any valid date</param>
  /// <param name="addDayOfWeek">Set this option to add the day of the week to the formatted date</param>
  /// <returns>A string containing the Juwish formatted date</returns>
  public static string GetHebrewJuwishDateString(DateTime anyDate, bool addDayOfWeek)
  {
   System.Text.StringBuilder hebrewFormatedString = new System.Text.StringBuilder();
   
   // Create the hebrew culture to use hebrew (Juwish) calendar
   CultureInfo juwishCulture = CultureInfo.CreateSpecificCulture("he-IL");
   juwishCulture.DateTimeFormat.Calendar = new HebrewCalendar();
 
   #region Format the date into a Juwish format

 

   if (addDayOfWeek)
   {
    // Day of the week in the format " "
    hebrewFormatedString.Append(anyDate.ToString("dddd", juwishCulture) + " ");
   }

 

   // Day of the month in the format "'"
   hebrewFormatedString.Append(anyDate.ToString("dd", juwishCulture) + " ");

 

   // Month and year in the format " "
   hebrewFormatedString.Append("" + anyDate.ToString("y", juwishCulture));

 

   #endregion

 

   return hebrewFormatedString.ToString();

 

  }

Thanks, Ido!
