-/**
- * <code>ChineseCalendar</code> is a concrete subclass of {@link Calendar}
- * that implements a traditional Chinese calendar.  The traditional Chinese
- * calendar is a lunisolar calendar: Each month starts on a new moon, and
- * the months are numbered according to solar events, specifically, to
- * guarantee that month 11 always contains the winter solstice.  In order
- * to accomplish this, leap months are inserted in certain years.  Leap
- * months are numbered the same as the month they follow.  The decision of
- * which month is a leap month depends on the relative movements of the sun
- * and moon.
- *
- * <p>This class defines one addition field beyond those defined by
- * <code>Calendar</code>: The <code>IS_LEAP_MONTH</code> field takes the
- * value of 0 for normal months, or 1 for leap months.
- *
- * <p>All astronomical computations are performed with respect to a time
- * zone of GMT+8:00 and a longitude of 120 degrees east.  Although some
- * calendars implement a historically more accurate convention of using
- * Beijing's local longitude (116 degrees 25 minutes east) and time zone
- * (GMT+7:45:40) for dates before 1929, we do not implement this here.
- *
- * <p>Years are counted in two different ways in the Chinese calendar.  The
- * first method is by sequential numbering from the 61st year of the reign
- * of Huang Di, 2637 BCE, which is designated year 1 on the Chinese
- * calendar.  The second method uses 60-year cycles from the same starting
- * point, which is designated year 1 of cycle 1.  In this class, the
- * <code>EXTENDED_YEAR</code> field contains the sequential year count.
- * The <code>ERA</code> field contains the cycle number, and the
- * <code>YEAR</code> field contains the year of the cycle, a value between
- * 1 and 60.
- *
- * <p>There is some variation in what is considered the starting point of
- * the calendar, with some sources starting in the first year of the reign
- * of Huang Di, rather than the 61st.  This gives continuous year numbers
- * 60 years greater and cycle numbers one greater than what this class
- * implements.
- *
- * <p>Because <code>ChineseCalendar</code> defines an additional field and
- * redefines the way the <code>ERA</code> field is used, it requires a new
- * format class, <code>ChineseDateFormat</code>.  As always, use the
- * methods <code>DateFormat.getXxxInstance(Calendar cal,...)</code> to
- * obtain a formatter for this calendar.
