Expand description

A field symbol for a date formatting pattern.

Field symbols are a more granular distinction for a pattern field within the category of a field type. Examples of field types are: Year, Month, Hour. Within the Hour field type, examples of field symbols are: Hour::H12, Hour::H24. Each field symbol is represented within the date formatting pattern string by a distinct character from the set of A..Z and a..z.

Variants§

§

Era

Era name.

§

Year(Year)

Year number or year name.

§

Month(Month)

Month number or month name.

§

Week(Week)

Week number or week name.

§

Day(Day)

Day number relative to a time period longer than a week (ex: month, year).

§

Weekday(Weekday)

Day number or day name relative to a week.

§

DayPeriod(DayPeriod)

Name of a period within a day.

§

Hour(Hour)

Hour number within a day, possibly with day period.
