Theyare not part of the source of Date.js, but to use them you can simply copy thisblock of code into any script that is included after Date.js and they will also becomeglobally available on the Date object. Feel free to add or remove patterns as needed in your code.<pre><code>Date.patterns = {ISO8601Long:<em>"Y-m-d H:i:s"</em>,ISO8601Short:<em>"Y-m-d"</em>,ShortDate: <em>"n/j/Y"</em>,LongDate: <em>"l, F d, Y"</em>,FullDateTime: <em>"l, F d, Y g:i:s A"</em>,MonthDay: <em>"F d"</em>,ShortTime: <em>"g:i A"</em>,LongTime: <em>"g:i:s A"</em>,SortableDateTime: <em>"Y-m-d\\TH:i:s"</em>,UniversalSortableDateTime: <em>"Y-m-d H:i:sO"</em>,YearMonth: <em>"F, Y"</em>};</code></pre>Example usage:<pre><code>var dt = <b>new</b> Date();document.write(dt.format(Date.patterns.ShortDate));</code></pre> </div><div class="hr"></div><a id="Date-props"></a><h2>Public Properties</h2><table cellspacing="0" class="member-table"><tr><th class="sig-header" colspan="2">Property</th><th class="msource-header">Defined By</th></tr><tr class="property-row"><td class="micon"><a class="exi" href="#expand"> </a></td><td class="sig"><a id="Date-Date.DAY"></a><b>Date.DAY</b> : String <div class="mdesc"><static> Date interval constant </div></td><td class="msource">Date</td></tr><tr class="property-row alt"><td class="micon"><a class="exi" href="#expand"> </a></td><td class="sig"><a id="Date-Date.HOUR"></a><b>Date.HOUR</b> : String <div class="mdesc"><static> Date interval constant </div></td><td class="msource">Date</td></tr><tr class="property-row"><td class="micon"><a class="exi" href="#expand"> </a></td><td class="sig"><a id="Date-Date.MILLI"></a><b>Date.MILLI</b> : String <div class="mdesc"><static> Date interval constant </div></td><td class="msource">Date</td></tr><tr class="property-row alt"><td class="micon"><a class="exi" href="#expand"> </a></td><td class="sig"><a id="Date-Date.MINUTE"></a><b>Date.MINUTE</b> : String <div class="mdesc"><static> Date interval constant </div></td><td class="msource">Date</td></tr><tr class="property-row"><td class="micon"><a class="exi" href="#expand"> </a></td><td class="sig"><a id="Date-Date.MONTH"></a><b>Date.MONTH</b> : String <div class="mdesc"><static> Date interval constant </div></td><td class="msource">Date</td></tr><tr class="property-row alt"><td class="micon"><a class="exi" href="#expand"> </a></td><td class="sig"><a id="Date-Date.SECOND"></a><b>Date.SECOND</b> : String <div class="mdesc"><static> Date interval constant </div></td><td class="msource">Date</td></tr><tr class="property-row"><td class="micon"><a class="exi" href="#expand"> </a></td><td class="sig"><a id="Date-Date.YEAR"></a><b>Date.YEAR</b> : String <div class="mdesc"><static> Date interval constant </div></td><td class="msource">Date</td></tr><tr class="property-row alt expandable"><td class="micon"><a class="exi" href="#expand"> </a></td><td class="sig"><a id="Date-Date.dayNames"></a><b>Date.dayNames</b> : Array <div class="mdesc"><div class="short"><static> An array of textual day names.Override these values for international dates, for example...Date.dayN...</div><div class="long"><static> An array of textual day names.Override these values for international dates, for example...Date.dayNames = ['SundayInYourLang', 'MondayInYourLang', ...];

Note that this function expects dates in normal calendarformat, meaning that months are 1-based (1 = January) and not zero-based like in JavaScript dates.
