When Pesach Begins on a Saturday Night

When Pesach Begins on a Saturday Night
Occasionally, Pesach begins on a motzaei Shabbat, that is, on Saturday night after the sabbath has concluded. This occurs in 5768 (2008). This complicates the process of preparing for Pesach, because many of the preparations normally undertaken on the day before Pesach cannot be performed on Shabbat.
The Fast of the Firstborn, normally observed on the day before Pesach, is observed on Thursday instead. The search for chametz, normally performed on the night before Pesach, is performed on Thursday night. The seder should be prepared for as much as possible before Shabbat begins, because time should not be taken away from Shabbat to prepare for Pesach. In addition, there are severe complications dealing with the conflict between the requirement of removing chametz no later than mid-morning on Saturday, the prohibition against eating matzah on the day before the seder, and the requirement of eating three meals with bread during Shabbat!
