This year Passover causes a big headache TB Pesakhim 49

 This year Passover with the first seder begins Saturday night after the conclusion of Shabbat on March 27^th. That means that the 14^th of Nisan falls on Shabbat itself which causes a big problem. We know that by the sixth hourⁱ of the 14th day of Nisan all hametz must be destroyed usually by burning it. What should a person do when one is forbidden to light a fire on Shabbat? That’s the topic of the first Mishna on Today’s daf TB Pesakhim 49.  

“With regard to the fourteenth of Nisan that occurs on Shabbat, one removes all leaven from his possession, whether it is teruma or non-sacred food, before Shabbat, except for that which will be eaten during the first part of Shabbat. In that case, one cannot remove leaven from his possession on the fourteenth of Nisan itself as he does in other years. This is the statement of Rabbi Meir. And the Rabbis say: One may remove the leaven at its usual time on the fourteenth of Nisan by throwing it away or declaring it ownerless. Rabbi Eliezer bar Tzadok says: Teruma should be removed before Shabbat, as only a few people are permitted to eat it and therefore one can presume that it will remain uneaten during Shabbat. However, non-sacred foods should be removed at their usual time, on the fourteenth of Nisan itself.” (Sefaria.org translation)

Although this Mishnah seems pretty straight forward, some surprising interpretations lead to different halakhic conclusions. Rabbi Zarakhiyah HaLevi, the author of the Maor, a commentary on the Ri”f, and several Gaonim understand that when the Mishna states “one removes all leaven from his possession,” it really means that absolutely no hametz exists in his procession. One eats matza in the morning instead of hallah since one is only forbidden to refrain from eating matza from noon on erev Passover.

Rabbi Zarakhiyah HaLevi comments that the underling argument between Rabbi Meir and the Sages concerns the despoal of the hametz. Rabbi Meir holds the position that burning the hametz in a fire is the only correct method while the Sages hold that other methods like crumbling the hametz and throw it up so that the wind will remove it are effective. Consequently, some hametz can be left to be destroyed on Shabbat itself at the usual time.

Another interesting interpretation understands the disagreement between Rabbi Meir and the Sages completely differently. Both sides agree the hametz must be destroyed on the 13th of Nisan when the 14th is Shabbat. They disagree on the timing. Rabbi Meir believes you may destroy the hametz up until you light Shabbat candles. The Sages say that a normal procedure pattern should be followed. In other words, one has until the beginning of the 6th hour on Friday to rid yourself of all hametz.

What should you do this year? You destroy all your hametz on Friday, March 26, but you may leave enough for two meals, Friday night and early Shabbat morning before the 6th hour. You have to be extremely careful not leave any crumbs behind nor hamatzdic your Passover dishes. (Shulkhan Arukh, Orekh Hayyim, 444:1) Me, I’m too neurotic to do that, so my whole household will be strictly Kosher for Passover by Friday night. Maybe, I'll use egg matza to make motzi over.

iRemember all hours are what I call Jewish time. The hour under discussion this year is 61 minutes.
