returns a number according to the sequence of seasons in a year: 1 for Winter, etc. Capitalization and spelling must be correct. If not a valid season, returns 0
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)
40-41 = Semestral 1, Semestral-2 (6 months each)

Date ranges, season dates, proper name dates are not currently supported.
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()
It is possible that a solution like that written for ht:Module:Citation/CS1/Date_validation date_name_xlate() could be applied to this problem
