- * \brief C API: Calendar
- *
- * <h2>Calendar C API</h2>
- *
- * UCalendar C API is used  for converting between a <code>UDate</code> object
- * and a set of integer fields such as <code>UCAL_YEAR</code>, <code>UCAL_MONTH</code>,
- * <code>UCAL_DAY</code>, <code>UCAL_HOUR</code>, and so on.
- * (A <code>UDate</code> object represents a specific instant in
- * time with millisecond precision. See UDate
- * for information about the <code>UDate</code> .)
- *
- * <p>
- * Types of <code>UCalendar</code> interpret a <code>UDate</code>
- * according to the rules of a specific calendar system. The U_STABLE
- * provides the enum UCalendarType with UCAL_TRADITIONAL and
- * UCAL_GREGORIAN.
- * <p>
- * Like other locale-sensitive C API, calendar API  provides a
- * function, <code>ucal_open()</code>, which returns a pointer to
- * <code>UCalendar</code> whose time fields have been initialized
- * with the current date and time. We need to specify the type of
- * calendar to be opened and the  timezoneId.
- * \htmlonly<blockquote>\endhtmlonly
- * <pre>
- * \code
- * UCalendar *caldef;
- * UChar *tzId;
- * UErrorCode status;
- * tzId=(UChar*)malloc(sizeof(UChar) * (strlen("PST") +1) );
- * u_uastrcpy(tzId, "PST");
- * caldef=ucal_open(tzID, u_strlen(tzID), NULL, UCAL_TRADITIONAL, &status);
- * \endcode
- * </pre>
- * \htmlonly</blockquote>\endhtmlonly
- *
- * <p>
- * A <code>UCalendar</code> object can produce all the time field values
- * needed to implement the date-time formatting for a particular language
- * and calendar style (for example, Japanese-Gregorian, Japanese-Traditional).
- *
- * <p>
- * When computing a <code>UDate</code> from time fields, two special circumstances
- * may arise: there may be insufficient information to compute the
- * <code>UDate</code> (such as only year and month but no day in the month),
- * or there may be inconsistent information (such as "Tuesday, July 15, 1996"
- * -- July 15, 1996 is actually a Monday).
- *
- * <p>
- * <strong>Insufficient information.</strong> The calendar will use default
- * information to specify the missing fields. This may vary by calendar; for
- * the Gregorian calendar, the default for a field is the same as that of the
- * start of the epoch: i.e., UCAL_YEAR = 1970, UCAL_MONTH = JANUARY, UCAL_DATE = 1, etc.
- *
- * <p>
- * <strong>Inconsistent information.</strong> If fields conflict, the calendar
- * will give preference to fields set more recently. For example, when
- * determining the day, the calendar will look for one of the following
- * combinations of fields.  The most recent combination, as determined by the
- * most recently set single field, will be used.
- *
- * \htmlonly<blockquote>\endhtmlonly
- * <pre>
- * \code
- * UCAL_MONTH + UCAL_DAY_OF_MONTH
- * UCAL_MONTH + UCAL_WEEK_OF_MONTH + UCAL_DAY_OF_WEEK
- * UCAL_MONTH + UCAL_DAY_OF_WEEK_IN_MONTH + UCAL_DAY_OF_WEEK
- * UCAL_DAY_OF_YEAR
- * UCAL_DAY_OF_WEEK + UCAL_WEEK_OF_YEAR
- * \endcode
- * </pre>
- * \htmlonly</blockquote>\endhtmlonly
- *
- * For the time of day:
- *
- * \htmlonly<blockquote>\endhtmlonly
- * <pre>
- * \code
- * UCAL_HOUR_OF_DAY
- * UCAL_AM_PM + UCAL_HOUR
- * \endcode
- * </pre>
- * \htmlonly</blockquote>\endhtmlonly
- *
- * <p>
- * <strong>Note:</strong> for some non-Gregorian calendars, different
- * fields may be necessary for complete disambiguation. For example, a full
- * specification of the historial Arabic astronomical calendar requires year,
- * month, day-of-month <em>and</em> day-of-week in some cases.
- *
- * <p>
- * <strong>Note:</strong> There are certain possible ambiguities in
- * interpretation of certain singular times, which are resolved in the
- * following ways:
- * <ol>
- *     <li> 24:00:00 "belongs" to the following day. That is,
- *          23:59 on Dec 31, 1969 &lt; 24:00 on Jan 1, 1970 &lt; 24:01:00 on Jan 1, 1970
- *
- *     <li> Although historically not precise, midnight also belongs to "am",
- *          and noon belongs to "pm", so on the same day,
- *          12:00 am (midnight) &lt; 12:01 am, and 12:00 pm (noon) &lt; 12:01 pm
- * </ol>
- *
- * <p>
- * The date or time format strings are not part of the definition of a
- * calendar, as those must be modifiable or overridable by the user at
- * runtime. Use {@link DateFormat}
- * to format dates.
- *
- * <p>
- * <code>Calendar</code> provides an API for field "rolling", where fields
- * can be incremented or decremented, but wrap around. For example, rolling the
- * month up in the date <code>December 12, <b>1996</b></code> results in
- * <code>January 12, <b>1996</b></code>.
- *
- * <p>
- * <code>Calendar</code> also provides a date arithmetic function for
- * adding the specified (signed) amount of time to a particular time field.
- * For example, subtracting 5 days from the date <code>September 12, 1996</code>
- * results in <code>September 7, 1996</code>.
