The Unix timestamp started on 01 Jan 1970 00:00:00 +0000 -- and that was a Thursday. The second before (i.e., 31 December, 1969 23:59:59:59 + 0000) was null, which was Wednesday. Now one might argue that everything before was null and I could accept that. But here's my code and reasoning, please follow: $string = null; $seconds = strtotime($string); // change string into seconds date = getdate($seconds); // change seconds into a date $computedDate = $date['mday'] . ' ' . $date['month'] . ', ' . $date['year'] . ' : ' .$date['weekday']; echo($computedDate); // show date Thus, null is Wednesday. Now, why is this wrong?
