This function does not work if it is fed month names for languages other than English. Wikimedia #time: parser
apparently doesn't understand non-Engish date month names. This function will always return false when the date
contains a non-English month name because good1 is false after the call to lang.formatDate(). To get around that
call this function with YYYY-MM-DD format dates.

Uses ISO DIS 8601 2016 part 2 §4.7 Divisions of a year for hemishpere-independent seasons:
21-24 = Spring, Summer, Autumn, Winter, independent of “Hemisphere”
These additional divisions not currently supported:
25-28 = Spring - Northern Hemisphere, Summer- Northern Hemisphere, Autumn - Northern Hemisphere, Winter - Northern Hemisphere
29-32 = Spring – Southern Hemisphere, Summer– Southern Hemisphere, Autumn – Southern Hemisphere, Winter - Southern Hemisphere
33-36 = Quarter 1, Quarter 2, Quarter 3, Quarter 4 (3 months each)
37-39 = Quadrimester 1, Quadrimester 2, Quadrimester 3 (4 months each)

format is one of several keywords: dmy, dmy-all, mdy, mdy-all, ymd, ymd-all. The all version includes access- and
archive-dates; otherwise these dates are not reformatted
Date ranges, season dates, proper name dates are not currently supported.
For i18n: This code works only at en.wiki because os.date() doesn't support any languages other than English.
mw.getContentLanguage():formatDate() will work at non-English wikis only when the date format is yyyy-mm-dd. This is
the same issue that plagues is_valid_accessdate()
