Listopad 10, 2011 or is it Listopada 10, 2011?
Listopad 10, 2011 would look weird, but Listopada 10, 2011 would be even weirder ;)
It should be:
10 Listopada 2011
10 Sierpnia 2011
10 Czerwca 2011
10 Maja 2011
Some people write it 10 Listopad/Sierpień/Czerwiec/Maj 2011 but that's not the most proper way as far as I know
