Mimouna — Practiced by Moroccan Sephardim; a celebratory meal after Pesach has ended with the intent that everyone be blessed with a prosperous year (Remember that Nissan is the first month, month-wise). Tables are laden with Mufletas (thin pancakes), sweets, pastries, candies, nuts and other rich delicacies. It has now developed into a quasi-holiday in Israel. One theory proposes that it falls on the yahrzeit of Rambam’s father Maimon. Another theory equates Mimouna with Shmona (8 day Pesach festival) and it’s intent to capture the flavor of Pesach into the following day.
Seudat HaMashiach — Instituted by the Ba’al Shem Tov and observed to be practiced by Chabad-Lubavitch Chassidim. A ‘final’ meal with Matzah and wine in which Nigunnim are sung, Chassidic discourses are given over. Seudat HaMashiach usually starts prior to Shkia on the final day and can continue well into the night.
Ne’ilas HaChag — Practiced by most mainstream Ashkenazic Kehillas on all the 3 yomim tovim to delay the departure of the festival. Food served is comparable to Seudas Shlishis on Shabbos.
