Rest of the Day on Erev Pesach

We don’t say Av Harachamim and Tzidkas’cha.

After Minchah, recite part of the Haggadah, from Avadim hayinu until lechaper al kol avonoseinu.

After Minchah but before shekiah, recite the Seder Korban Pesach.

Preparations for the Seder may not be started on Shabbos. After Shabbos, one must say “Baruch hamavdil bein kodesh lekodesh” before commencing preparations.
