แม่แบบ:Date table sorting

คู่มือการใช้งานแม่แบบ[ดู] [แก้] [ประวัติ] [ล้างแคช]

Date table sorting stands for Date Table Sorting 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.

This template automatically creates the hidden <span style="display:none">1776-07-04</span> for sorting purposes and then displays the date like this:

• July 4, 1776

Parameters

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) 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.

1st parameter – the full date in international, US or ISO format It uses {{#time:}} and so is limited to what the parser function can handle (e.g. it won't go beyond 100 AD). International format is left as it is. ISO format defaults to US format. Abbreviated months are accepted. Capitilisation and comma mistakes are corrected.

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.

• {{TBA}} - allows quarters, and allows sorting of time periods by end date.
• m:แม่แบบ:dts (backlinks edit) - since on Meta e.g. 09999 9999 induces numeric sort mode, "&" is prefixed to force string sort mode.
• {{dts1}}
• {{dts vgr}} - for video game release dates.
