Don't forget that one must stop eating on Saturday night before sunset. It's best to stop a few minutes before at 7:20. One should change to non-leather shoes after 7:50. After 8:03 one should say ברוך המבדיל בין קודש לחול and recite the Bracha בורא מאורי האש on artificial light. From Saturday night until 1:00 p.m. on Sunday, one should act as if he is sitting Shiva. He sits on a low chair and does not greet people. From 1:00, we begin anticipating the Redemption and are in a lesser state of mourning. This Shabbat is called Shabbat Chazon as we read the third prophecy of rebuke. Some refrain from learning Torah from Chatzot on Shabbat. We all Daven Mincha early so that there is plenty of time for our סעודה המפסקת. We are allowed to eat meat and drink wine at this meal. Shabbat Shalom and may we see the גאולה speedily.
