  • Enum Constant Details

    • OFFICIAL

      public static final Nengo.Selector OFFICIAL

      Selects all nengos with the exception of those of the northern court in the Nanboku-chō period (1336-1392).

      This selector is the default.

    • MODERN

      public static final Nengo.Selector MODERN

      Selects only nengos from Meiji onwards (introduction of japanese-gregorian calendar in year 1873 = Meiji 6).

    • EDO_PERIOD

      public static final Nengo.Selector EDO_PERIOD

      Selects all nengos of the Edo period (1603-1868).

      See also Wikipedia.

    • AZUCHI_MOMOYAMA_PERIOD

      public static final Nengo.Selector AZUCHI_MOMOYAMA_PERIOD

      Selects all nengos of the Azuchi-Momoyama period (1573-1603).

      See also Wikipedia.

    • MUROMACHI_PERIOD

      public static final Nengo.Selector MUROMACHI_PERIOD

      Selects all nengos of the Muromachi period (1336-1573).

      See also Wikipedia. The nengos of the Kenmu-restoration do not belong to this period. Furthermore, all nengos of the northern court are excluded because otherwise a historical order of generated lists is hard to achieve.

    • NORTHERN_COURT

      public static final Nengo.Selector NORTHERN_COURT

      Selects the nengos of the northern court only (during the Nanboku-chō period 1336-1392 and in addition, the nengo Shōkei (1332)).

      The northern variant of the Nengo Kenmu (Kenmu restoration) is also matched by this selector.

    • SOUTHERN_COURT

      public static final Nengo.Selector SOUTHERN_COURT

      Selects the nengos of the southern court only (during the Nanboku-chō period 1336-1392).

      The southern variant of the Nengo Kenmu (Kenmu restoration) is also matched by this selector. Historical note: The last year 10 of nengo Genchū was then replaced by Meitoku 4.

    • KAMAKURA_PERIOD

      public static final Nengo.Selector KAMAKURA_PERIOD

      Selects all nengos of the Kamakura period (1185-1332).

      See also Wikipedia

    • HEIAN_PERIOD

      public static final Nengo.Selector HEIAN_PERIOD

      Selects all nengos of the Heian period (794-1185).

      See also Wikipedia

    • NARA_PERIOD

      public static final Nengo.Selector NARA_PERIOD

      Selects all nengos of the Nara period (710-794).

      See also Wikipedia

    • ASUKA_PERIOD

      public static final Nengo.Selector ASUKA_PERIOD

      Selects all nengos of the Asuka period (538-710).

      See also Wikipedia. Time4J only supports the last three nengos of this period because the historical data are not exactly known and there were also historical gaps in nengo counting.
