With Pesach (Passover) falling after Shabbat this year, there are some special rules to follow. Here's a few sources, though the best source is your community orthodox rabbi.
For followers of Chabad hassidus, this short compendium in hebrew is available.
The Hirhurim blog posted the email he received from his rabbi here.
Torah.org has a nice Q & A about Shabbos Erev Pesach here.
Good Shabbos, and a Hag Kasher v'Samayach (a kosher and happy holiday!) with the Geulah Shalayma (complete redemption!) if we don't meet again before then.
