ThreeTen-Extra 1.8.0 · org.threeten.extra.chrono.JulianEra

An era in the Julian calendar system.

The Julian calendar system has two eras. The current era, for years from 1 onwards, is known as 'Anno Domini'. All previous years, zero or earlier in the proleptic count or one and greater in the year-of-era count, are part of the 'Before Christ' era.

The start of the Julian epoch 0001-01-01 (Julian) is 0000-12-30 (ISO).

Do not use ordinal() to obtain the numeric representation of JulianEra. Use getValue() instead.

Implementation Requirements:

This is an immutable and thread-safe enum.
