No official announcement on a start date yet. Don't expect good communications about this from Niantic, they won't say anything until 2 days before at the most.
Last years Halloween event was the first ever Pokemon Go event and it ran 10/26 to 11/1. It featured increased candy and increased appreances from various spooky Gen1 mons.
