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; 99 Christmas 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) ]] local function make_COinS_date (input, tCOinS_date) local date; -- one date or first date in a range local date2 = ''; -- end of range date -- start temporary Julian / Gregorian calendar uncertainty detection local year = tonumber(input.year); -- this temporary code to determine the extent of sources dated to the Julian/Gregorian local month = tonumber(input.month); -- interstice 1 October 1582 – 1 January 1926 local day = tonumber (input.day); if (0 ~= day) and -- day must have a value for this to be a whole date (((1582 == year) and (10 <= month) and (12 >= month)) or -- any whole 1582 date from 1 october to 31 December or ((1926 == year) and (1 == month) and (1 == input.day)) or -- 1 January 1926 or ((1582 < year) and (1925 >= year))) then -- any date 1 January 1583 – 31 December 1925 tCOinS_date.inter_cal_cat = true; -- set category flag true end -- end temporary Julian / Gergorian calendar uncertainty detection if 1582 > tonumber(input.year) or 20 < tonumber(input.month) then -- Julian calendar or season so &rft.date gets year only date = input.year; if 0 ~= input.year2 and input.year ~= input.year2 then -- if a range, only the second year portion when not the same as range start year date = string.format ('%.4d/%.4d', tonumber(input.year), tonumber(input.year2)) -- assemble the date range end if 20 < tonumber(input.month) then -- if season or propername date local season = {[24]='winter', [21]='spring', [22]='summer', [23]='fall', [99]='Christmas'}; -- seasons lowercase, no autumn; proper names use title case if 0 == input.month2 then -- single season date if 30 <tonumber(input.month) then tCOinS_date.rftchron = season[input.month]; -- proper name dates else tCOinS_date.rftssn = season[input.month]; -- seasons end else -- season range with a second season specified if input.year ~= input.year2 then -- season year – season year range or season year–year tCOinS_date.rftssn = season[input.month]; -- start of range season; keep this? if 0~= input.month2 then tCOinS_date.rftchron = string.format ('%s %s – %s %s', season[input.month], input.year, season[input.month2], input.year2); end else -- season–season year range tCOinS_date.rftssn = season[input.month]; -- start of range season; keep this? tCOinS_date.rftchron = season[input.month] ..

Months, both long-form and three character abbreviations, and seasons must be spelled correctly. Future years beyond next year are not allowed. If the date fails the format tests, this function returns false and does not return values for anchor_year and COinS_date.
