>From ISO 8601-1:2019(E): 5.2.3 Ordinal date
5.2.3.1 Complete representations A complete representation of an ordinal date shall be as follows. a) Basic format: [year][dayo] EXAMPLE 1 1985102 b) Extended format: [year][“-”][dayo] EXAMPLE 2 1985-102 If by agreement, expanded representations are used, the formats shall be as specified below. The interchange parties shall agree on the additional number of digits in the time scale component year. 5.2.3.2 Expanded representations In the examples below it has been agreed to expand the time scale component year with two digits. a) Basic format: [±][year(6)][dayo] EXAMPLE 1 +001985102 b) Extended format: [±][year(6)][“-”][dayo] EXAMPLE 2 +001985-102 > On 5 Feb 2021, at 6:45 am, José Valim <[email protected]> wrote: > > > I like José's suggesting of supporting a flag, but it gets kind of > complicated as there are several dimensions here even in our reduced case. > Dates, times, and datetimes support either basic or extended notations; dates > and datetimes support calendar dates or ordinal dates; both are applicable to > any parsing. > > Are we 100% sure that ordinal datetimes are part of ISO8601?
