<P>
<code>Calendar</code> is an abstract class for getting and setting dates using a set of integer fields such as <code>YEAR</code>, <code>MONTH</code>, <code>DAY</code>, and so on. (A <code>Date</code> object represents a specific instant in time with millisecond precision. See <A HREF="../../java/util/Date.html"><CODE>Date</CODE></A> for information about the <code>Date</code> class.) <p> Subclasses of <code>Calendar</code> interpret a <code>Date</code> according to the rules of a specific calendar system. <p> Like other locale-sensitive classes, <code>Calendar</code> provides a class method, <code>getInstance</code>, for getting a generally useful object of this type. <blockquote> <pre> Calendar rightNow = Calendar.getInstance(); </pre> </blockquote> <p> A <code>Calendar</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>Date</code> from time fields, there may be insufficient information to compute the <code>Date</code> (such as only year and month but no day in the month). <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., YEAR = 1970, MONTH = JANUARY, DATE = 1, etc. <p> <strong>Inconsistent information.</strong> In the J2SE calendar, it is possible to set fields inconsistently. However, in this subset, the DAY_OF_WEEK field cannot be set, and only a subset of the other J2SE Calendar fields are included. So it is not possible to set inconsistent data. <p> <strong>Note:</strong> The ambiguity in interpretation of what day midnight belongs to, is resolved as so: midnight "belongs" to the following day.<br> 23:59 on Dec 31, 1969 < 00:00 on Jan 1, 1970.<br> 12:00 PM is midday, and 12:00 AM is midnight.<br> 11:59 PM on Jan 1 < 12:00 AM on Jan 2 < 12:01 AM on Jan 2.<br> 11:59 AM on Mar 10 < 12:00 PM on Mar 10 < 12:01 PM on Mar 10.<br> 24:00 or greater are invalid. Hours greater than 12 are invalid in AM/PM mode. Setting the time will never change the date. <p> If equivalent times are entered in AM/PM or 24 hour mode, equality will be determined by the actual time rather than the entered time. <p> This class is a subset for J2ME of the J2SE Calendar class. Many methods and variables have been pruned, and other methods simplified, in an effort to reduce the size of this class.
