This function receives a table of date parts for one or two dates and an empty table reference declared in
Module:Citation/CS1. The function is called only for |date= parameters and only if the |date=<value> is
determined to be a valid date format. The question of what to do with invalid date formats is not answered here.
 
The date parts in the input table are converted to an ISO 8601 conforming date string:
single whole dates: yyyy-mm-dd
month and year dates: yyyy-mm
year dates: yyyy
ranges: yyyy-mm-dd/yyyy-mm-dd
yyyy-mm/yyyy-mm
yyyy/yyyy
 
Dates in the Julian calendar are reduced to year or year/year so that we don't have to do calendar conversion from
Julian to Proleptic Gregorian.
 
The input table has:
year, year2 – always present; if before 1582, ignore months and days if present
month, month2 – 0 if not provided, 1-12 for months, 21-24 for seasons; 31– proper name dates
day, day2 – 0 if not provided, 1-31 for days
the output table receives:
rftdate: an IS8601 formatted date
rftchron: a free-form version of the date, usually without year which is in rftdate (season ranges and propername dates)
rftssn: one of four season keywords: winter, spring, summer, fall (lowercase)

Reformats existing dates into the format specified by format and short.
 
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()
 
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
