The Purim Seudah

If you did not eat your meal before chatzos, have it before “the tenth hour”, which is about 3 hours before shekiah. If “the tenth hour” has already passed, one should still eat the meal before shekiah.

Care should be taken not to forget to daven Kabbolas Shabbos and Maariv. The Rebbe once mentioned that the Rema would go from house to house at the end of Purim and remind the townspeople to daven Maariv.
