International Components for Unicode for Java (icu4j) 74.2 · com.ibm.icu.util.JapaneseCalendar

JapaneseCalendar is a subclass of GregorianCalendar that numbers years and eras based on the reigns of the Japanese emperors. The Japanese calendar is identical to the Gregorian calendar in all respects except for the year and era. The ascension of each emperor to the throne begins a new era, and the years of that era are numbered starting with the year of ascension as year 1.

Note that in the year of an imperial ascension, there are two possible sets of year and era values: that for the old era and for the new. For example, a new era began on January 7, 1989 AD. Strictly speaking, the first six days of that year were in the Showa era, e.g. "January 6, 64 Showa", while the rest of the year was in the Heisei era, e.g. "January 7, 1 Heisei". This class handles this distinction correctly when computing dates. However, in lenient mode either form of date is acceptable as input.

In modern times, eras have started on January 8, 1868 AD, Gregorian (Meiji), July 30, 1912 (Taisho), December 25, 1926 (Showa), and January 7, 1989 (Heisei). Constants for these eras, suitable for use in the ERA field, are provided in this class. Note that the number used for each era is more or less arbitrary. Currently, the era starting in 645 AD is era #0; however this may change in the future. Use the predefined constants rather than using actual, absolute numbers.

Since ICU4J 63, start date of each era is imported from CLDR. CLDR era data may contain tentative era in near future with placeholder names. By default, such era data is not enabled. ICU4J users who want to test the behavior of the future era can enable this by one of following settings (in the priority order):

Java system property ICU_ENABLE_TENTATIVE_ERA=true.
Environment variable ICU_ENABLE_TENTATIVE_ERA=true.
Java system property jdk.calendar.japanese.supplemental.era=xxx. (Note: This configuration is used for specifying a new era's start date and names in OpenJDK. ICU4J implementation enables the CLDR tentative era when this property is defined, but it does not use the start date and names specified by the property value.)

This class should not be subclassed.

JapaneseCalendar usually should be instantiated using com.ibm.icu.util.Calendar#getInstance(ULocale) passing in a ULocale with the tag "@calendar=japanese".
