#5334 – When Are We Eating?

Remah (O.H. 695: 2) rules that when Purim is on Erev Shabbos, one should make the Seudah in the morning in honor of Shabbos. Mishna Berura (10) explains that it is before Chatzos or midday.

However Yad Efraim and others permit to eat the Seuda, before the ninth hour of the day. Some Poskim maintain that in such a case when one davens after midday, one should see to daven Mincha before the Seuda. Many advise to eat the Seuda in the morning.
