+/**
+ * A date in the Hijrah calendar system.
+ * <p>
+ * This date operates using the {@linkplain HijrahChronology Hijrah calendar}.
+ * <p>
+ * The Hijrah calendar has a different total of days in a year than
+ * Gregorian calendar, and a month is based on the period of a complete
+ * revolution of the moon around the earth (as between successive new moons).
+ * The calendar cycles becomes longer and unstable, and sometimes a manual
+ * adjustment (for entering deviation) is necessary for correctness
+ * because of the complex algorithm.
+ * <p>
+ * HijrahDate supports the manual adjustment feature by providing a configuration
+ * file. The configuration file contains the adjustment (deviation) data with following format.
+ * <pre>
+ * StartYear/StartMonth(0-based)-EndYear/EndMonth(0-based):Deviation day (1, 2, -1, or -2)
+ * Line separator or ";" is used for the separator of each deviation data.</pre>
+ * Here is the example.
+ * <pre>
+ * 1429/0-1429/1:1
+ * 1429/2-1429/7:1;1429/6-1429/11:1
+ * 1429/11-9999/11:1</pre>
+ * The default location of the configuration file is:
+ * <pre>
+ * $CLASSPATH/java/time/i18n</pre>
+ * And the default file name is:
+ * <pre>
+ * hijrah_deviation.cfg</pre>
+ * The default location and file name can be overriden by setting
+ * following two Java's system property.
+ * <pre>
+ * Location: java.time.i18n.HijrahDate.deviationConfigDir
+ * File name: java.time.i18n.HijrahDate.deviationConfigFile</pre>
