Template:Dts/doc

 stands for D ate T able S orting and is used to correctly sort and display dates in a sortable table (see Help:Sorting).

What it solves
Normally, for proper sorting, dates must be entered in YYYY-MM-DD format. However, that format does not conform to the Manual of Style for date display and wikilinking.

This template automatically creates the hidden  for sorting purposes and then displays the date like this:
 * plain text July 4, 1776 (default, link=off)
 * wikilinked July 4 1776, format depends on the user's Special:Preferences (if link=on is specified)

Parameters

 * 1st parameter - Year (optional if month is given)
 * Year number - number in the range -9999 through 9999: the numbers -9999 through 0 are used without "bc" and represent astronomical years -9999 through 0, the numbers 1 through 9999 represent that year AD, or BC with the fourth parameter set to bc or BC
 * 2nd parameter - Month (optional if the day is not given either)
 * Full month name - February or february
 * Abbreviated month name - Feb or feb
 * Month number - 2 or 02
 * 3rd parameter - Day (optional)
 * Day number - 7 or 07
 * 4th parameter - optional with value BC or bc
 * Used with a positive year number

Thus e.g. for the year 5 BC we can use "5|bc" or "-4".

A time period (year or month and year) is sorted according to its start, and time periods with the same starting moment are in order of descending length: a year comes before its first month; a month comes before its first day.

Error handling
During early 2009, Template:Dts generated month names for invalid month numbers, such as number 23 displaying "November". No warning is displayed, for the formatted page, that such invalid dates are being used on the page.
