Q:
A: Dusserah is in the month of Kartik 5 days before the full Moon. Usually falls in Sept- October. On the last Hindu Calendar day and the start of the next month/ i.e on Amavasya, Diwali is celebrated. Oct- Nov. Could not locate a calendar of that year . So just go to a temple; the priests have a Panchang and will help you with it.
