public enum IsoEra extends Enum<IsoEra> implements Era
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.
year-of-era | era | proleptic-year |
---|---|---|
2 | CE | 2 |
1 | CE | 1 |
1 | BCE | 0 |
2 | BCE | -1 |
Do not use ordinal()
to obtain the numeric representation of IsoEra
. Use getValue()
instead.
