copied!<p>Here you go: <code>/^[A-Z]{1}[a-z]{2}\s[0-9]{1,2},\s[0-9]{4},\s[0-9]{1,2}[a|p]m\s[A-Z]{3}\:$/</code></p> <pre><code>'Nov 18, 2013, 4pm CST'.match(/^[A-Z]{1}[a-z]{2}\s[0-9]{1,2},\s[0-9]{4},\s[0-9]{1,2}[a|p]m\s[A-Z]{3}\:$/) ["Nov 18, 2013, 4pm CST"] </code></pre> <p>Keep in mind that this regex is expecting the line to start and end with this date, if the date is contained within other text, remove the <code>^</code> from the start and the <code>$</code> from the end. </p> <p>Hope this helps.</p> <p>To further explain the regex and hopefully ++ your "regex-fu"</p> <ul> <li>[A-Z]{1} - match one upper case letter</li> <li>[a-z]{2} - match two lower case letters</li> </ul> <p>So far we are at Nov, Oct, Jan, etc.</p> <ul> <li>\s - space</li> <li>[0-9]{1,2} - a 1 (min) or 2 (max) digit number</li> <li>, - literal comma</li> <li>\s - space</li> <li>[0-9]{4} - a 4 digit number (the year)</li> </ul> <p>So now we have matched: Nov 18, 2013</p> <ul> <li>, - literal comma</li> <li>\s - space</li> <li>[0-9]{1,2} - just like before, a one or two digit number</li> <li>[a|p]m - 'a' or 'p' followed by an 'm'</li> </ul> <p>Now we've matched: Nov 18, 2013, 4pm</p> <ul> <li>[A-Z]{3} An upper case three character string</li> <li>\: literal colon</li> </ul> <p>That is the entire string. </p> <p>Putting <code>^</code> at the beginning of the regex means the text we are matching against MUST begin with the pattern; similarly, the <code>$</code> states that the text we are matching MUST end with the pattern.</p> <p>Good luck!</p>
