Der bliver nedenfor brugt regulære udtryk som er forklaret i |

|||
F.eks. matcher %d et tal mellem 0 og 9, %a et bogstav fra a til z, %s matcher et mellerumstegn |
|||
Desuden betyder +-tegnet 1 eller flere gentagelser af foregående tegn, |
|||
?-tegnet betyder nul eller 1 gentagelse, mens * betyder 0 eller flere gentagelser af foregående tegn |
|||
. (punktum) matcher et hvilket som helst tegn |
|||
%- matcher en bindestreg og %. matcher et punktum |
|||
[1-9] er en såkaldt tegnklasse der matcher et af tallene fra 1 til 9, |
|||
mens f.eks. tegnklassen [a-zå] matcher et bogstav fra a til z samt et å |
|||
^ betyder begyndelsen af strengen og $ betyder i slutningen. |

This module contains routines that support the Citation Style 1 and Citation Style 2 date formats for citations on Wikipedia. In particular, this module contains a suite of functions that validate date formats and content for the variety of date-holding parameters associated with cs1|2 citations.
See Skabelon:Citation/testcases and Moduldiskussion:Citation/CS1/Date validation/testcases for testcase with validation of dates.

Check a pair of months or seasons to see if both are valid members of a month or season pair.
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, ...,
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.

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)

Check date format to see that it is one of the formats approved by WP:DATESNO or WP:DATERANGE. Exception: only
allowed range separator is endash. Additionally, check the date to see that it is a real date: no 31 in 30-day
months; no 29 February when not a leap year. 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. When this happens, the date parameter is used in the COinS metadata and the CITEREF identifier gets
its year from the year parameter if present otherwise CITEREF does not get a date value.
Inputs:
date_string - date string from date-holding parameters (date, year, accessdate, embargo, archivedate, etc.)
Returns:
false if date string is not a real date; else
true, anchor_year, COinS_date
anchor_year can be used in CITEREF anchors
COinS_date is ISO 8601 format date; see make_COInS_date()
Der bliver nedenfor brugt regulære udtryk som er forklaret i
https://www.mediawiki.org/wiki/Extension:Scribunto/Lua_reference_manual#Patterns
F.eks. matcher %d et tal mellem 0 og 9, %a et bogstav fra a til z, %s matcher et mellerumstegn
Desuden betyder +-tegnet 1 eller flere gentagelser af foregående tegn,
?-tegnet betyder nul eller 1 gentagelse, mens * betyder 0 eller flere gentagelser af foregående tegn
. (punktum) matcher et hvilket som helst tegn
%- matcher en bindestreg og %. matcher et punktum
[1-9] er en såkaldt tegnklasse der matcher et af tallene fra 1 til 9,
mens f.eks. tegnklassen [a-zå] matcher et bogstav fra a til z samt et å
^ betyder begyndelsen af strengen og $ betyder i slutningen.

Cycle the date-holding parameters in passed table date_parameters_list through check_date() to check compliance with MOS:DATE. For all valid dates, check_date() returns
true. The |date= parameter test is unique, it is the only date holding parameter from which values for anchor_year (used in CITEREF identifiers) and COinS_date (used in
the COinS metadata) are derived. The |date= parameter is the only date-holding parameter that is allowed to contain the no-date keywords "n.d." or "nd" (without quotes).
Unlike most error messages created in this module, only one error message is created by this function. Because all of the date holding parameters are processed serially,
a single error message is created as the dates are tested.

2 - year value matches the year value in date when date is in the form YYYY-MM-DD and year is disambiguated (|year=YYYYx)

Date ranges, season dates, proper name dates are not currently supported.

Loops through the list of date-holding parameters and converts any ndash to hyphen. Not called if the cs1|2
template has any date errors.
Modifies the date_parameters_list and returns true if hyphens are replaced, else returns false.
Funktionen retter ikke kun bindestreger til tankestreger, men er tilpasset testen i
Moduldiskussion:Citation/CS1/Date validation/testcases
således at årstalsintervaller (1963-1968) og datointervaller indenfor samme måned (3.-5. juni 2019) og
månedsintervaller indenfor samme år (maj-juni 2019) alle bruger bindestreg, mens tankestreg foretrækkes
ved andre datointervaller (f.eks. 3. maj – 5. juni 2019, 3. maj 2018 – 5. juni 2019, maj 2018 – juni 2019)
Desuden skal der være mellemrum omkring tankestreg, men ikke omkring bindestreg
