Class HybridDate

java/core/src/java/org/threeten/extra/chrono/HybridDate.java:57–543

A date in the British Cutover calendar system. This date operates using the plain HybridChronology British Cutover calendar. Implementation Requirements This class is immutable and thread-safe. This class must be treated as a value type. Do not synchronize, rely on the ident

 * identity hash code or use the distinction between equals() and ==.
