I had this issue today. I found <a href="http://momentjs.com/" rel="noreferrer">momentjs</a> was a good way of parsing ISO 8601 dates in a cross browser manor.

momentjs can also be used to output the date in a different format.

The ES5 spec deviates from the ISO8601 spec, especially when it comes to the treatment of dates without a timezone indicator / offset. There is a bug ticket at <a href="https://bugs.ecmascript.org/show_bug.cgi?id=112" rel="nofollow">https://bugs.ecmascript.org/show_bug.cgi?id=112</a> describing the problem and it looks like it will be fixed in ES6.

For now, I recommend looking at <a href="https://github.com/csnover/js-iso8601" rel="nofollow">https://github.com/csnover/js-iso8601</a> for a cross-browser implementation. I use <a href="https://github.com/csnover/js-iso8601/tree/lax" rel="nofollow">https://github.com/csnover/js-iso8601/tree/lax</a> which doesn't conform to the ES5 spec but has better interoperability with other JSON serialisation libraries such as JSON.NET.

As mentioned previously ISO 8601 style dates were added in ECMAScript version 5, where implementation is not consistent, and not available in all browsers. There are a <a href="https://github.com/kriskowal/es5-shim/blob/master/es5-shim.js" rel="nofollow">number</a> <a href="http://frugalcoder.us/post/2010/01/07/EcmaScript-5s-Date-Extensions.aspx" rel="nofollow">of</a> script stubs available, but you may wish to simply add your own Date.parse* method.

<pre><code>(function() {
 //ISO-8601 Date Matching
 var reIsoDate = /^(\d{4})-(\d{2})-(\d{2})((T)(\d{2}):(\d{2})(:(\d{2})(\.\d*)?)?)?(Z|[+-]00(\:00)?)?$/;
 Date.parseISO = function(val) {
 var m;

 m = typeof val === 'string' && val.match(reIsoDate);
 if (m) return new Date(Date.UTC(+m[1], +m[2] - 1, +m[3], +m[6] || 0, +m[7] || 0, +m[9] || 0, parseInt((+m[10]) * 1000) || 0));

 return null;
 }

 //MS-Ajax Date Matching
 var reMsAjaxDate = /^\\?\/Date$(\-?\d+)$\\?\/$/;
 Date.parseAjax = function(val) {
 var m;

 m = typeof val === 'string' && val.match(reMsAjaxDate);
 if (m) return new Date(+m[1]);

 return null;
 }
}();</code></pre>

I use the above method for JSON.parse hydration of dates...

<pre><code>JSON.parse(text, function(key, val) {
 return Date.parseISO(val) || Date.parseAjax(val) || val;

blocks|key|917305|text|我发现ckozl答案非常有用和有趣，但regexp并不完美，它在我的例子中不起作用。|type|unstyled|depth|inlineStyleRanges|entityRanges|data|917306|除了不包含分钟、秒或milisecs的日期不能解析之外，ISO8501规范还规定'-‘和':’分隔符是可选的，因此"2013-12-27“和"20131227”都是有效的。在我的例子中，这很重要，因为我在PHP的JavaScript变量中设置了服务器日期和时间：|917307|var+serverDate+=+new+Date(Date.parse("<?php+date(DateTime::ISO8601);+?>"));|code-block|syntax|javascript|917308|这段代码生成的代码如下所示：|917309|<script>

I found ckozl answer really useful and interesting, but the regexp is not perfect and it didn't work in my case.

Apart from the fact that dates without minutes, secs or milisecs are not parsed, ISO 8501 spec says that the '-' and ':' separators are optional, so "2013-12-27" and "20131227" are both valid. In my case, this is important because I'm setting the server date and time in a JavaScript variable from PHP:

<pre><code>var serverDate = new Date(Date.parse("&lt;?php date(DateTime::ISO8601); ?&gt;"));
</code></pre>

This code generates something like this:

<pre><code>&lt;script&gt;
var serverDate = new Date(Date.parse("2013-12-27T15:27:34+0100"));
&lt;/script&gt;
</code></pre>

The important part is the time zone designator "+0100" where the ':' is missing. Although Firefox parses that string correctly, IE (11) fails (if the ':' is added, then IE also works). The headache about the zonetime and the ECMAScript specifications described by ckozl is unimportant in my case, because PHP always add the time zone designator.

The RegExp I'm using, instead of that one from ckozl is:

<pre><code>var regexIso8601 = /^(\d{4}|\+\d{6})(?:-?(\d{2})(?:-?(\d{2})(?:T(\d{2})(?::?(\d{2})(?::?(\d{2})(?:(?:\.|,)(\d{1,}))?)?)?(Z|([\-+])(\d{2})(?::?(\d{2}))?)?)?)?)?$/;
</code></pre>

Keep in mind that this regexp is not perfect either. ISO 8501 allows week specification (2007-W01-1 for monday, 1 Jan 2007), or decimal fractions in hours and minutes (18.50 for 18:30:00, or 18:30.25 for 18:30:15). But they are quite unusual.

P.D. This answer should be, I imagine, a comment to the original chozl answer, but I do not have reputation enough :(

Microsoft Sharepoint 2013 is ALSO using a different notation eg "2013-04-30T22:00:00Z" 

If you want to use the REST services from sharepoint 2013 in combination with Internet Explorer 8 ( IE8 ) , then the solution from ckozl is NOT working. 
Youll get the NaN

change the regex line TO:

<pre><code>regexIso8601 = /^(\d{4}|\+\d{6})(?:-(\d{2})(?:-(\d{2})(?:T(\d{2}):(\d{2}):(\d{2})(\.(\d{1,3}))?(?:Z|([\-+])(\d{2}):(\d{2}))?)?)?)?$/;
</code></pre>

this will make the microseconds bit optional !

I failed to parse an ISO-8601 date "2011-04-26T13:16:50Z" on IE8 and Safari 5, but it worked on Chrome 10, FF4. Support seems to be quite mixed? 

Does anyone know the actual status of which browsers can parse this format? I assume IE6, and 7 will fail too.

<pre><code>var d = Date.parse("2011-04-26T13:16:50Z");
</code></pre>

我无法在IE8和Safari5上解析ISO-8601日期"2011-04-26T13:16:50Z“，但它在Chrome10和FF4上可以工作。支持似乎相当复杂？有没有人知道哪些浏览器可以解析这种格式的实际状态？我假设IE6和7也会失败。var d = Date.parse("2011-04-26T13:16:50Z");
