Simchat Torah is somewhere in October usually, but it's kind of a nothing holiday. Certainly the observance of it would require no more than a day off work for the devout. Just a small do where they roll the Torah back to the beginning.
Sukkot also sometimes falls in October, but its a harvest festival and also having no tradition that would last for a month, nor is a holiday that requires again, much more than a day off work for the devout.
