Why does everyone want to write hooks in Python?

On the command line, you can do this with something like:

 hg id -r "$SOMENODE and not date('-180')"

and get a non-zero return code if the set is empty.

A datetime is presumably a number in seconds since (the local) UNIX
epoch. Mercurial dates are all of the form:

 (seconds since epoch in GMT, seconds offset from GMT)

so this comparison won't work. You should instead use
util.matchdate("-180").
