測試後無誤的版本可以一次性地加入此模块中，但是修改前請務必於<a href="/w/index.php?title=Module_talk:Date&action=edit&redlink=1" class="new" title="Module talk:Date（页面不存在）">討論頁</a>發起討論。 <hr /> 模板引用數量會自動更新。</td></tr></tbody></table> 本模块为其他模块提供日期相关的函数。目前支持<a href="/wiki/%E5%85%AC%E5%8E%86" title="公历">公历</a>和<a href="/wiki/%E5%84%92%E7%95%A5%E6%9B%86" title="儒略曆">儒略曆</a>的日期，有效范围从公元前999年至公元9999年。使用的日期都应当是<a href="/wiki/%E5%89%8D%E5%85%AC%E5%8E%86" class="mw-redirect" title="前公历">公历前推的</a>，也就是说所有的时间都是唯一且确定的。 日期，包含可选的时间，可以用多种格式指定，并且可以通过多种格式进行显示转换，例如：1 April 2016 或 April 1, 2016。一个日期的属性包括它的儒略日期和公历序列日期，以及星期几和一年中的第几天。 日期是可比的（例如，<code>date1 <= date2</code>），并且可以相加或相减（例如，<code>date + '3 months'</code>）。两个日期之间的差异可以通过 <code>date1 - date2</code> 来确定。这些操作适用于公历和儒略历日期，但如果两个日期混用不同的历法，<code>date1 - date2</code> 将为空。 该模块提供以下内容： <table class="wikitable"> <tbody><tr> <th>模块导出</th> <th>描述 </th></tr> <tr> <td><code>_current</code></td> <td>包含当前年月日时分秒的表（table） </td></tr> <tr> <td><code>_Date</code></td> <td>返回包含指定日期的表（table）的函数 </td></tr> <tr> <td><code>_days_in_month</code></td> <td>返回某个月的天数的函数 </td></tr></tbody></table> <div class="mw-heading mw-heading2"><h2 id="格式化输出">格式化输出</h2></div> 日期可以以文字形式输出： <div class="mw-highlight mw-highlight-lang-lua mw-content-ltr" dir="ltr"><pre>local Date = require('Module:Date')._Date local text = Date(2016, 7, 1):text() -- 输出 '1 July 2016' local text = Date(2016, 7, 1):text('%-d %B') -- 输出 '1 July' local text = Date('1 July 2016'):text('mdy') -- 输出 'July 1, 2016' </pre></div> 模块提供了下列格式代码简写： <table class="wikitable"> <tbody><tr> <th>代码</th> <th>结果 </th></tr> <tr> <td>hm</td> <td>hour:minute, 包含"am"或"pm" or variant, if specified (14:30 or 2:30 pm or variant) </td></tr> <tr>

<td>day month year (1 July 2016) </td></tr></tbody></table> 以下格式化代码（类似于C语言的 <a href="/wiki/Time.h#时间日期数据的格式化函数" title="Time.h">strftime</a>）可用于格式化输出日期： <table class="wikitable"> <tbody><tr> <th>代码</th> <th>结果 </th></tr> <tr> <td>%a</td> <td>Day abbreviation: Mon, Tue, ... </td></tr> <tr> <td>%A</td> <td>Day name: Monday, Tuesday, ... </td></tr> <tr> <td>%u</td> <td>Day of week: 1 to 7

<td>Hour: 1 to 12 </td></tr> <tr> <td>%%</td> <td>% </td></tr></tbody></table> 此外，可以使用<code>%{property}</code>（其中 <code>property</code> 是日期的任何属性）来进行格式化。 例如，<code>Date('1 Feb 2015 14:30:45 A.D.')</code> 具有以下属性： <table class="wikitable"> <tbody><tr> <th>代码</th> <th>结果 </th></tr> <tr> <td>%{calendar}</td> <td>Gregorian </td></tr> <tr> <td>%{year}</td> <td>2015 </td></tr> <tr> <td>%{month}</td> <td>2 </td></tr> <tr> <td>%{day}</td> <td>1 </td></tr> <tr> <td>%{hour}</td> <td>14 </td></tr> <tr> <td>%{minute}</td> <td>30 </td></tr> <tr> <td>%{second}</td> <td>45 </td></tr> <tr> <td>%{dayabbr}</td> <td>Sun </td></tr> <tr> <td>%{dayname}</td> <td>Sunday </td></tr> <tr> <td>%{dayofweek}</td> <td>0 </td></tr> <tr> <td>%{dow}</td> <td>0 (same as dayofweek) </td></tr> <tr> <td>%{dayofweekiso}</td> <td>7 </td></tr> <tr> <td>%{dowiso}</td> <td>7 (same as dayofweekiso) </td></tr> <tr> <td>%{dayofyear}</td> <td>32 </td></tr> <tr> <td>%{era}</td> <td>A.D. </td></tr> <tr> <td>%{gsd}</td> <td>735630 (numbers of days from 1 January 1 CE; the first is day 1) </td></tr> <tr> <td>%{juliandate}</td> <td>2457055.1046875 (<a href="/wiki/Julian_day" class="mw-redirect"

</td></tr> <tr> <td>%{monthabbr}</td> <td>Feb </td></tr> <tr> <td>%{monthname}</td> <td>February </td></tr></tbody></table> 一些快捷方式也是可用的。给定 <code>date = Date('1 Feb 2015 14:30')</code>，将产生以下结果： <table class="wikitable"> <tbody><tr> <th>代码</th> <th>描述</th> <th>结果</th> <th>等同于 </th></tr> <tr> <td>date:text('%c')</td> <td>date and time</td> <td>2:30 pm 1 February 2015</td> <td>%-I:%M %p %-d

%p </td></tr></tbody></table> <div class="mw-heading mw-heading2"><h2 id="儒略日期">儒略日期</h2></div> 下面是一个将儒略日期转换为日期，并获取日期信息的示例： <div class="mw-highlight mw-highlight-lang-lua mw-content-ltr" dir="ltr"><pre>-- 代码 -- 结果 Date = require('Module:Date')._Date date = Date('juliandate', 320) number = date.gsd -- -1721105 number = date.jd -- 320 text = date.dayname -- Saturday text = date:text() -- 9 October 4713&nbsp;BC text = date:text('%Y-%m-%d') -- 4713-10-09 text = date:text('%{era} %Y-%m-%d') -- BC 4713-10-09 text = date:text('%Y-%m-%d %{era}') -- 4713-10-09&nbsp;BC text =

Date(-4712,10,9):text('%{gsd} %{jd}') -- -1721105 320 </pre></div> <div class="mw-heading mw-heading2"><h2 id="日期差">日期差</h2></div> 两个日期之间的差值可以通过 <code>date1 - date2</code> 来确定。如果两个日期都使用公历或儒略历，那么计算的结果是有效的；如果两个日期使用不同的历法，那么计算的结果将为空值。日期差异可以被用于计算年龄和时间间隔。 例子： <div class="mw-highlight mw-highlight-lang-lua mw-content-ltr" dir="ltr"><pre>-- 代码 -- 结果 Date = require('Module:Date')._Date date1 = Date('21 Mar 2015') date2 = Date('4 Dec 1999') diff = date1 - date2 d = diff.age_days -- 5586 y, m, d = diff.years, diff.months, diff.days -- 15, 3, 17 (15 years + 3 months + 17 days) y, m, d = diff:age('ymd') -- 15, 3, 17 y, m, w, d = diff:age('ymwd') -- 15, 3, 2, 3 (15 years + 3 months + 2 weeks + 3 days) y, m, w, d = diff:duration('ymwd') -- 15, 3, 2, 4 d = diff:duration('d') -- 5587 (duration 包含最后一天) </pre></div> 日期差包含原始的日期，只是它们可能被交换以满足 <code>diff.date1 >= diff.date2</code> 的条件（其中 <code>diff.date1</code> 是较靠后的日期）。以下是示例说明： <div class="mw-highlight mw-highlight-lang-lua mw-content-ltr" dir="ltr"><pre>date1 = Date('21 Mar 2015') date2 = Date('4 Dec 1999') diff = date1 - date2 neg = diff.isnegative -- false text = diff.date1:text() -- 21 March 2015 text = diff.date2:text() -- 4 December 1999 diff = date2 - date1 neg = diff.isnegative -- true (日期被交换了) text = diff.date1:text() -- 21 March 2015 text = diff.date2:text() -- 4 December 1999 </pre></div> 除了包含日期之间的差，还包含时间之间的差： <div class="mw-highlight mw-highlight-lang-lua mw-content-ltr" dir="ltr"><pre>date1 = Date('8 Mar 2016 0:30:45') date2 = Date('19 Jan 2014 22:55') diff = date1 - date2 y, m, d = diff.years, diff.months, diff.days -- 2, 1, 17 H, M, S = diff.hours, diff.minutes, diff.seconds -- 1, 35, 45 </pre></div> 日期差值可以被加到一个日期上，也可以从一个日期上减去： <div class="mw-highlight mw-highlight-lang-lua mw-content-ltr" dir="ltr"><pre>date1 = Date('8 Mar 2016 0:30:45') date2 = Date('19 Jan 2014 22:55') diff = date1 - date2 date3 = date2 + diff date4 = date1 - diff text = date3:text('ymd hms') -- 2016-03-08 00:30:45 text = date4:text('ymd hms') -- 2014-01-19 22:55:00 equal = (date1 == date3) -- true equal = (date2 == date4) -- true </pre></div> 年龄和时间间隔的日期差可以接受一个代码，用于指定需要返回的日期间隔组成部分。对于时间间隔，会额外包含一天，因为它包含了最后一天： <table class="wikitable"> <tbody><tr> <th>代码</th> <th>返回值 </th></tr> <tr> <td><code>'ymwd'</code></td> <td>years, months, weeks, days </td></tr> <tr> <td><code>'ymd'</code></td> <td>years, months, days </td></tr> <tr> <td><code>'ym'</code></td> <td>years, months </td></tr> <tr> <td><code>'y'</code></td> <td>years </td></tr> <tr> <td><code>'m'</code></td> <td>months </td></tr> <tr> <td><code>'wd'</code></td> <td>weeks, days </td></tr> <tr> <td><code>'w'</code></td> <td>weeks </td></tr> <tr> <td><code>'d'</code></td> <td>days
