Eating after sunset on Shabbat

Hi,

We have already noted that one may not begin a meal before reciting Havdalah, after sunset on Shabbat, even if one does not intend to end Shabbat for hours.

However, one who has not yet eaten Seudah Shlishit (the third meal of Shabbat) should start it even after sunset, until 30 minutes before the stars emerge (about ten minutes after sunset, depending on one's latitude and the time of year).

(Code of Jewish Law Orach Chaim 299:1; Mishneh Berurah 299:1)

Have a great day,
Mordechai
