Calendar Types

Calendar types are used to specify calendar systems for which the getDisplayName and getDisplayNames methods provide calendar field value names. See Calendar.getCalendarType() for details.

Calendar Fields

Calendar fields are specified with the constants defined in Calendar. The following are calendar-common fields and their values to be supported for each calendar system.

Field values
Field Value Description
Calendar.MONTH Calendar.JANUARY to Calendar.UNDECIMBER Month numbering is 0-based (e.g., 0 - January, ..., 11 - December). Some calendar systems have 13 months. Month names need to be supported in both the formatting and stand-alone forms if required by the supported locales. If there's no distinction in the two forms, the same names should be returned in both of the forms.
Calendar.DAY_OF_WEEK Calendar.SUNDAY to Calendar.SATURDAY Day-of-week numbering is 1-based starting from Sunday (i.e., 1 - Sunday, ..., 7 - Saturday).
Calendar.AM_PM Calendar.AM to Calendar.PM 0 - AM, 1 - PM

The following are calendar-specific fields and their values to be supported.
