Re: Date math

I have this math equation this list helped me generate a few weeks ago. The purpose is to calculate how many days have passed between 2 dates. Right now my output ($difference) is 93.9583333333 days. I am finding this a little weird. Does anyone see anything wrong with the way this is calculated: $date1 = strtotime($date1); (March 21st 2008) $date2 = strtotime($date2); (December 18th 2007) echo $date1 => 1206072000 echo $date2 => 1197954000 #86400 is 60 seconds x 60 minutes x 24 hours (in other words 1 days worth of seconds) $factor = 86400; $difference = (($date1 - $date2) / $factor);

As Casey suggested, it is a timestamp issue.
