The ISO Calendar
The ISO Calendar is a standardized solar calendar with twelve months. It is identical to the Gregorian calendar, except it uses negative years for years before 1 CE, and may have differing formatting data for a given locale.
This type can be used with Date
or DateTime
to represent dates in this calendar.
Era codes
This calendar supports one era, "default"
