Here is a function to calculate the difference between to dates, in days (assuming the dates are PHP timestamps):

function dateDiff($date1, $date2) {
Description: This will calculate the
difference, in days, between the two
supplied dates.
Assumptions: Date1 is larger than Date2
(If not, the function will return -1)
if ($date1 > $date2) {
$calc_day_diff = ($date1 - $date2) / 86400;
else {
$calc_day_diff = -1;

return ($calc_day_diff);

I hope this helps,
