Longest Gap between bunch of dates in excel
<p>I have a column of dates, and I want to find the maximum gap between 2 dates. How would we do it in excel?</p>

<p>May 6, 2015
May 9, 2015
May 14, 2015
May 17, 2015
May 21, 2015</p>

<p>For example, this should give the answer, May 14 - May 9 = 5 days is the longest gap</p>

<p>Thanks in advance!</p>
