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.
For the time being, to use this function, supply it with YYYY-MM-DD format dates.  See
[[bs:Modul:Citation/CS1/Date validation/igralište]] for one possible solution.

Month pairs are expected to be left to right, earliest to latest in time.
Month pairs are expected to be left to right, earliest to latest in time.


Similarly, seasons are also left to right, earliest to latest in time.  There is an oddity with seasons: winter is assigned a value of 1, spring 2, ...,
All season ranges are accepted as valid because there are publishers out there who have published a Summer–Spring YYYY issue so ... ok
fall and autumn 4. Because winter can follow fall/autumn at the end of a calender year, a special test is made to see if |date=Fall-Winter yyyy (4-1) is the date.

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
