Andoza:COinS safe

Dts (date time sorting) is used to correctly sort and display dates in a sortable table (see Help:Sorting).

What it solves[tahrir]

Dates in their customary formats, if simply treated as alphanumeric text strings, sort in nonsensical ways:

  • 1/8/2013 sorts alphanumerically before 5/3/1967, because 1 is less than 5;
  • February 5, 1922 sorts alphanumerically before January 3, 1922, because F comes before J.

Use of the YYYY-MM-DD format would solve this problem, but with minor exceptions that format is not used in articles (see WP:DATEFORMAT).

This template automatically attaches a "hidden key" to dates, causing them to sort correctly while still being displayed in one of the customary display formats such as February 5, 1922 or 5 Feb 1922.

Parameters[tahrir]

Dates[tahrir]

The year, month and day can either be entered separately or as a single date.
{{dts|year|month|day|BC}} {{dts|date}}
  • 1st parameter – Year (optional if month is given)
    • Positive number (1 to 999,999,999,999) represent years AD or BC (dependant on the fourth parameter).
    • Negative numbers (−1 to −999,999,999,999) represent years BC (without the fourth parameter).
    • Year numbers must not contain commas or other formatting.
  • 2nd parameter – Month (optional if the day is not given either)
    • Full month name – e.g. February
    • Abbreviated month name – e.g. Feb
    • Month number – (either zero-padded or not) e.g. 2 or 02
  • 3rd parameter – Day (optional)
    • Day number – (either zero-padded or not) e.g. 7 or 07
  • 4th parameter – (optional)
    • May be BC, AD, BCE or CE
    • Used with a positive year number
  • 1st parameter – the full date
    • By default YYYY-MM-DD format becomes month-day-year format while other formats remain in the order they are input.
    • Abbreviated months are accepted and are abbreviated in the output.
    • Capitalisation and comma mistakes are corrected.
    • A single number is interpreted as a year, otherwise the date is parsed by the module. The following formats are accepted:
      • YYYY-MM-DD
      • DD-MM-YYYY
      • DD Month YYYY
      • Month DD, YYYY
      • YYYY-MM
      • DD Month
      • Month DD
      • Month YYYY
      • YYYY
      • Month
    • Day and month numbers may be 1 or 2 digits, and year numbers may only be 3 or 4 digits. If you need to input a number less than 1000, use leading zeroes (e.g. "0700").
    • BC years can only be parsed if the date is only the year number.
    • If you need to include the day or month for BC years or years greater than 9999, you must use separate parameters for year, month and day.

Formatting[tahrir]

Using format produces a format that depends on, but is not necessarily equal to the format of the supplied date. The format parameter can take nine values.

Abbreviation[tahrir]

There are two ways of abbreviating the month name.

  1. Directly input an abbreviated month name.
  2. Use the abbr=on parameter.

{{dts|2000|1|1|abbr=on}} Andoza:Dts/outhide1 Yan 1, 2000

Additional sort key[tahrir]

In case two dates in a table are identical they may be ordered using the addkey parameter.

Examples

{{dts|2010-10-10|addkey=3}} Andoza:Dts/outhide0 Andoza:Dts/out0
{{dts|2010-10-09}} Andoza:Dts/outhide0 Andoza:Dts/out0
{{dts|2010-10-10|addkey=1}} Andoza:Dts/outhide0 Andoza:Dts/out0

{{dts|2010-10-10|addkey=2}} Andoza:Dts/outhide0 Andoza:Dts/out0

Wrapping[tahrir]

To turn off the suppression of word wraps, use the nowrap=off parameter.

Notes[tahrir]

Sorting for incomplete dates[tahrir]

Whole months or years
A whole year or month (and year) is sorted according to its first day.
Missing years
If the year is not specified, the date will be sorted as if the year were the current year.
Blank dates
For no date input at all, the maximum possible sort key is used, so the entry will sort last.

Error handling[tahrir]

Entering an invalid date format will (generally) produce an error message such as the one below.

Error: 35 June 1900
This is not an acceptable date format. Please check the spelling, numbers, and/or read the documentation at template {{dts}} for correct date input.

Errors are tracked in Category:Dts templates with errors.

Calendar choice[tahrir]

The template is not capable of distinguishing Julian and Gregorian calendar dates. Also, it is not capable of taking a date in one calendar as input and outputting a date in the other calendar. Thus, to insure proper sorting, editors must either use one calendar for all dates, or pick a specific changeover date (for example, deciding that 4 October 1582 is Julian and all later dates are Gregorian); this would be done on an article-by article basis. Editors are also responsible for explaining to the reader whether the visible dates are Julian or Gregorian, if there is any possibility of confusion.

Linking[tahrir]

The template formerly linked dates automatically, with link=off used to suppress linking. In accordance with current guidelines linking of dates is no longer supported and instances of link=off should be removed. Transclusions using the |link= parameter are tracked in Category:Dts templates with deprecated parameters.
