<div class="long">
<static> Parses the passed string using the specified format. 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. Any part ofthe date format that is not specified will default to the current date value for that part. Time parts can alsobe specified, but default to 0. Keep in mind that the input date string must precisely match the specified formatstring or the parse operation will fail.Example Usage:<pre><code><i>//dt = Fri May 25 2007 (current date)</i><b>var</b> dt = <b>new</b> Date();<i>//dt = Thu May 25 2006 (today's month/day <b>in</b> 2006)</i>dt = Date.parseDate(<em>"2006"</em>, <em>"Y"</em>);<i>//dt = Sun Jan 15 2006 (all date parts specified)</i>dt = Date.parseDate(<em>"2006-01-15"</em>, <em>"Y-m-d"</em>);<i>//dt = Sun Jan 15 2006 15:20:01 GMT-0600 (CST)</i>dt = Date.parseDate(<em>"2006-01-15 3:20:01 PM"</em>, <em>"Y-m-d h:i:s A"</em> );</code></pre> <div class="mdetail-params">

<div class="long">
Provides a convenient method of performing basic date arithmetic. This methoddoes not modify the Date instance being called - it creates and returnsa new Date instance containing the resulting date value.Examples:<pre><code><i>//Basic usage:</i><b>var</b> dt = <b>new</b> Date(<em>'10/29/2006'</em>).add(Date.DAY, 5);document.write(dt); <i>//returns <em>'Fri Oct 06 2006 00:00:00'</em></i><i>//Negative values will subtract correctly:</i><b>var</b> dt2 = <b>new</b> Date(<em>'10/1/2006'</em>).add(Date.DAY, -5);document.write(dt2); <i>//returns <em>'Tue Sep 26 2006 00:00:00'</em></i><i>//You can even chain several calls together <b>in</b> one line!</i><b>var</b> dt3 = <b>new</b> Date(<em>'10/1/2006'</em>).add(Date.DAY, 5).add(Date.HOUR, 8).add(Date.MINUTE, -30);document.write(dt3); //returns <em>'Fri Oct 06 2006 07:30:00'</em></code></pre> <div class="mdetail-params">

<div class="long">
Creates and returns a new Date instance with the exact same date value as the called instance.Dates are copied and passed by reference, so if a copied date variable is modified later, the originalvariable will also be changed. When the intention is to create a new variable that will notmodify the original instance, you should create a clone.Example of correctly cloning a date:<pre><code><i>//wrong way:</i><b>var</b> orig = <b>new</b> Date(<em>'10/1/2006'</em>);<b>var</b> copy = orig;copy.setDate(5);document.write(orig); <i>//returns <em>'Thu Oct 05 2006'</em>!</i><i>//correct way:</i><b>var</b> orig = <b>new</b> Date(<em>'10/1/2006'</em>);<b>var</b> copy = orig.clone();copy.setDate(5);document.write(orig); //returns <em>'Thu Oct 01 2006'</em></code></pre> <div class="mdetail-params">
