True for the proleptic Gregorian calendar, not necessarily so for other calendars. Since ISO8601 is explicitly only concerned with that calendar I expect this isn’t an issue. However given ordinal days of the year do exist for all calendars (that I’m aware of since they all have the concept of a day) perhaps adding a callback to `Calendar` of something like `month_and_day_from_ordinal(year, ordinal)` would be something to consider? Then of course implement that for `Calendar.ISO`. > On 5 Feb 2021, at 6:16 am, Christopher Keele <[email protected]> wrote: > > Ordinal dates are interesting because while they are not calendar dates, they > are trivially convertible into them. -- You received this message because you are subscribed to the Google Groups "elixir-lang-core" group.
