This definitely sounds useful. We should certainly extend our syntax to
support this, and the code for it wouldn't even be that difficult.

However: we'd first have to come up with a nice syntax for it. I'd
assume we probably want to allow not only the last day of the month, but
any day counted from the end of the month. It would appear natural to
use negative numbers for that, so that "5" is the fifth day, and "-5"
the day five days before the end of the month. However, the dash is
already used to separate the day from the month, so that would look a
little awkward.

Suggestions what we could do instead?

"2012-02-:4" maybe?




Other suggestions?
