in reply to Broken Date Handling

Because '09' is treated as an octal number (starts with '0'), but the highest digit in base 8 is 7.

Update:
So the script will fail on the 9th of every month, and on every day in September - a total of 41 days. Or it will work 89% of the time - isn't that good enough :-)

Update 2:
Aha, I didn't notice the $m--

I must admit that on first glance I wouldn't have seen the problem unless it was pointed out that the code was failing. It's the sort of bug that causes lots of swearing at the computer, then a very loud 'Doh!' when you fix it...

    Yeah. So I fixed it by adding

    $d += 0;

    to the code.

    The script doesn't fail in September. But it fails on both the 8th and the 9th of every month.

      Why doesn't it fail in September then? Or August, for that matter?

      Of course, you've already done a calculation on that value. Doh.

        Because the $m-- converts $m to a number.
