 /**
  * <code>PersianCalendar</code> is a subclass of <code>Calendar</code>
  * that implements the Persian calendar.  It is used as the official
  * calendar in Iran.  This calendar is also known as the "Hijri Shamsi"
  * calendar, since it starts at the time of Mohammed's emigration (or
  * "hijra") to Medinah on Thursday, July 15, 622 AD (Julian) and is a
  * solar calendar system (or "shamsi").
  * <p>
  * The Persian calendar is strictly solar, and thus a Persian year has twelve
  * solar months. A Persian year is about 365 days long, except in leap years
  * which is 366 days long.
  * <p>
  * The six first months of Persian Calendar are 31 days long. The next five
  * months are 30 days long. The last month is 29 days long in normal years,
  * and 30 days long in leap years.
