I fail to follow. Your code is looking ahead to next month (April), then using the 0 day, which means it's getting the last day (31) of the current month (March). There's no such thing as a 0 April, hence anything less than one should count backward. -- </Daniel P. Brown> Network Infrastructure Manager http://www.php.net/
