Mincha
One should be careful to pray Mincha (the afternoon prayer) with concentration. Elijah, the prophet, was answered when he prayed Mincha. On Rosh Hashanah this prayer is especially significant since Mincha was established by our patriarch Isaac, and on Rosh Hashanah we are trying to evoke the merit of Isaac’s being bound on the akeidah in order to transform G-d’s judgment into mercy.
We read the Torah at Mincha as we do every Shabbat afternoon.
We do not say Tzidkatecha at mincha since it mentions judgment, and we do not want to bring about any extra judgment on this day.
Tashlich Delayed
It is customary in many communities to delay Tashlich to the second day of Rosh Hashanah when the first day coincides with Shabbat.
One may not prepare for the second night (or day) of Yom Tov until after candle-lighting time.
