Explores the Mitzvah to study Hilchos Pesach beginning thirty days before Yomtov, and analyzes the source of this obligation and discusses whether it is a Chiyuv Min Hatorah or not. Also discussed whether one is merely obligated to learn the material or must be actively involved in anticipation of the upcoming Chag.  We will also discuss the Minhag as it is practiced today, and how it relates to the Shabbos Hagadol Drasha delivered by Rabbonim right before Pesach.
