A common practice for the Shabbat that comes the day after the seven of Khag Matzot (Feast of Unleavened Bread) is to continue the celebration one more day, calling it Shemeni shel Pesakh (Eighth Day of Passover).
A regular practice is to reflect on these Torah readings: Deuteronomy 14:22-16:17; Numbers 28:19-25. A common reading from the Prophets is Isa. 10:32-12:6.
