Question

I calculate the amount of days between two dates like this:

                    $start = strtotime($_SESSION['sdate']); 
                    $end = strtotime($_SESSION['hdate']); 
                    echo ($end - $start); 
                    $duration = ($end - $start) / 3600 /24; 
                    $duration+=1; //plus one day 
                    echo " The ad will show for ".$duration." day(s)<br/>"; 

Which generally works fine but things seem to mess up when I have a
start sdate of 2012-02-29 and an hdate of 2012-04-01. I get a duration
of: 32.9583333333
Why is this? That’s messing up my calculations. Is there a better way
to do this?
Thanks!

I think that it is because of the DST time change, which occurs on the last Sunday of March.
