<?php
        $DAYS = 3600 * 24;
        $fdom = mktime( 0, 0, 0, 10, 8, 2000 );
        for ($i = 1; $i < 30; $i++)
                echo date( "d.m.Y", $fdom + ($i - 1) * $DAYS ) . " ";
?>

This script should list the day number from October, 08th, through the next 30 days. It repeats the 29th day of October. I don't know why.

If the 3rd line is changed to
        $fdom = mktime( 0, 0, 0, 10, 08, 2000 );
date counting starts on September 30th, so the leading 0 of "08" is misinterpreted as a standalone zero.
