Expand description
An enum for the possible symbols of a year field in a date pattern.
Variants§
Calendar = 0
Field symbol for calendar year (numeric).
In most cases the length of this field specifies the minimum number of digits to display, zero-padded as necessary. For most use cases, Year::Calendar
or Year::WeekOf
should be adequate.
This field symbol is represented by the character y
in a date formatting pattern string.
For more details, see documentation on date field symbols.
WeekOf = 1
Field symbol for year in “week of year”.
This works for “week of year” based calendars in which the year transition occurs on a week boundary; may differ from calendar year Year::Calendar
near a year transition. This numeric year designation is used in conjunction with Week::WeekOfYear
, but can be used in non-Gregorian based calendar systems where week date processing is desired. The field length is interpreted in the same way as for Year::Calendar
.
This field symbol is represented by the character Y
in a date formatting pattern string.
For more details, see documentation on date field symbols.
Cyclic = 2
Field symbol for cyclic year; used in calendars where years are tracked in cycles, such as the Chinese or Dangi calendars.
This field symbol is represented by the character U
in a date formatting pattern string.
For more details, see documentation on date field symbols.
RelatedIso = 3
Field symbol for related ISO; some calendars which use different year numbering than ISO, or no year numbering, may express years in an ISO year corresponding to a calendar year.
This field symbol is represented by the character r
in a date formatting pattern string.
For more details, see documentation on date field symbols.
