This is the short date pattern, currently defined as "ddMMyyyy".

This is the long date pattern, currently defined as "dddd, dd MMMM yyyy".

The ISO-8601 round-trippable date pattern, "yyyy-MM-dd".

The month-and-day partial pattern (no year), currently "MMMM dd", e.g. March 03.

The year-and-month partial pattern (no day), currently "yyyy MMMM", e.g. 2020 March.

Absolute year of at least w digits. Width 1 is the no-padding case (reads 1-4 digits, so both "3" and "2020" parse; formats with no leading zeros); width n >= 2 reads exactly n digits. The value is always the literal year and is never truncated, so this is the strict counterpart to pyy (which does two-digit century inference). Values 0-9999 (note: not all dates will be valid in all calendars, if the date is too early it will clamp to earliest valid date)

Absolute year in exactly 4 digits (pyear 4); values 0000-9999.

Two-digit year of the era with the century inferred, mirroring Noda Time's yy specifier (contrast with the strict, absolute pyear). Formatting emits year mod 100 zero-padded to two digits, so 2020 becomes "20" and 2005 becomes "05". Parsing reads exactly two digits and expands them to the year with those final two digits that is closest to the parse template (the default passed to parse, whose year is 2000 for the Gregorian epoch), breaking ties toward the future. With the default template this maps "20" to 2020 and "99" to 1999; supply a different template via parse' to slide the 100-year window.

Month of year as a number of w digits, zero-padded; a width of 1 means no padding. Values 1-12.

Month of year as a zero-padded number (pmonthNum 2); values 01-12.

Abbreviated month name (e.g. Jan), parsed case-insensitively and formatted in title case.

NOTE: the abbreviation is simply the first three letters of the month name, so in calendars where two months share a three-letter prefix (e.g. the Hebrew AdarI and Adar) parsing is ambiguous and resolves to the first match in month order. Use pMMMM (full name) or pMM (number) when you need an unambiguous round-trip.

Full month name, parsed case-insensitively. Formats in title case

Abbreviated month name in the given Locale; the locale-aware counterpart to pMMM.

Full month name in the given Locale (e.g. März); the locale-aware counterpart to pMMMM.

Format and parse the month using an explicit list of names (index 0 is the calendar's first month), instead of the calendar's built-in English constructor names. This is the calendar-agnostic core behind the locale-aware pMMMM' and pMMM'; pass monthNames (or monthNamesShort) for OS locale names, or any list of the right length for a custom calendar. Parsing is case-insensitive and, like pMMMM, tries the names in order.

Day of month of w digits, zero-padded; a width of 1 means no padding. Values 1-31.

Day of month, zero-padded (pday 2); values 01-31.

Day of month, space-padded to two characters (the strftime %e convention), e.g. " 3" or "15". On parse it also accepts the bare and zero-padded forms.

Abbreviated day of week name (e.g. Mon), parsed case-insensitively and formatted in title case. Note: on parse this only consumes the weekday, it is not validated against the day/month/year (which fully determine the date).

Full day of week name (e.g. Monday), parsed case-insensitively and formatted in title case. Note: on parse this only consumes the weekday, it is not validated against the day/month/year (which fully determine the date).

Abbreviated weekday name in the given Locale; the locale-aware counterpart to pddd.

Full weekday name in the given Locale (e.g. Sonntag); the locale-aware counterpart to pdddd.

Format and parse the day-of-week using an explicit list of names (index 0 = Sunday), instead of the calendar's built-in English constructor names. This is the calendar-agnostic core behind pdddd' / pddd'. As with pdddd, parsing only consumes the weekday; it is not validated against the day/month/year.
