On Shabbat afternoon, it is advisable to hold the Mincha prayer earlier than usual, so that people can return home in time and calmly eat the seudah hamafseket (pre-fast meal). At the seudah hamafseket (which is essentially the third Shabbat meal), there are no restrictions on eating meat or drinking wine. However, one must completely stop eating and drinking by sunset.
Until Shabbat officially ends, it is forbidden to prepare anything for after Shabbat, to change clothes or shoes, or to sit on a low chair. When Shabbat ends, one should say: “Baruch hamavdil bein kodesh lechol” (Blessed is He who separates between the holy and the mundane) — (without G-d's Name or Kingship). After that, we recite the blessing “Borei me’orei ha’esh” (who creates the lights of fire) over a torch or two joined candles (but not the blessing over spices, which are a form of enjoyment). At that point, one changes into weekday clothes and cloth shoes. Driving to the synagogue is permitted. The full Havdalah over wine is postponed until Sunday night.
On Sunday night, after the fast ends and after Ma’ariv, one should wash hands alternately six times (as done when rising in the morning), rinse the face and mouth, put on regular shoes, and recite Havdalah over wine (without candle or spices). Only afterward does one eat.
