iso property
Returns a calendar system that follows the rules of the ISO-8601 standard, which is compatible with Gregorian for all modern dates.
This calendar system is equivalent to gregorian. The only areas in which the calendars differed were around centuries, and the members relating to those differences were removed. The distinction between Gregorian and ISO has been maintained for the sake of simplicity, compatibility and consistency.
Implementation
static final CalendarSystem iso = _isoCalendarSystem;
