IsoEra

public final enum IsoEra
extends Enum<IsoEra> implements Era

java.lang.Object
   ↳ java.lang.Enum<java.time.chrono.IsoEra>
     ↳ java.time.chrono.IsoEra


An era in the ISO calendar system.

The ISO-8601 standard does not define eras. A definition has therefore been created with two eras - 'Current era' (CE) for years on or after 0001-01-01 (ISO), and 'Before current era' (BCE) for years before that.

1BCE0
2BCE-1

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