AP's period during which you can renew runs from 60 days before expiration of current AP to 30 days after that expiration date. You never renew TIW but instead buy a new one when you arrive at WDW for the first trip during which you want to use it. Your TIW does not expire October 1, so check for its actual date which should be the end of a month, and if you purchased it October 1, 2015, or purchased it on any other day in October 2015, its expiration date will be November 30, 2016.
