Ugh! I do know some German and I probably remembered wrongly. But it doesn't really take away from my point that August is not a month name every where.
It doesn't matter what the month was named after, the fact is that now it's a month and can therefore be unisex.
Yes, in countries where August is a month too. I realise that we see this from different perspectives but you can't insist that August must be unisex because it is a month in English. There are a whole world out there where English is not the native language. Would you take a Japanese name that was strictly masculine and use it for a girl because it happens to look/sound/mean something/ feminine in English?
