Today's daf is sponsored by Cheryl & Avi Savitsky and family on the occasion of the 39th yahrzeit of Cheryl's father – Dr. Steven F. Stein – Shimon Feivish ben Yisroel Yitzchak Ha'Cohen, whose simchat ha'chaim was palpable to anyone who met him and is something we strive to emulate that each and every day. Today’s daf is sponsored by Suri Stern in memory of her father Harav Reuvain ben Chaim zt"l, on his  yahrzeit. “A warm and loving talmid chacham." Today’s daf is sponsored by Rachel and Oren Seliger in memory of Rachel’s father, Allen Kronisch, Avner Yosef Ben Yehuda Arye and Zlata Priva, on his 33rd yahrzeit. . “Too many years have passed. Always thinking of you! You would be so proud of your children learning Daf Yomi. Our father was a chozer b'teshuva and was always in admiration of those that learned the Daf.” One can only have their vows annulled (through a chacham/beit din) on Shabbat if it is for Shabbat. What about a husband/father who wants to nullify his wife's/daughter's vows on Shabbat? Is it also only permitted if necessary for Shabbat? A braita is brought which says they can only be nullified for the sake of Shabbat. however, Rav Ashi questions this from our Mishna. The conclusion is that it is a subject of debate among tannaim, and connects with the two opinions about whether one has twenty-four hours or just until nightfall to nullify her vows. One can nullify vows if it is for Shabbat, but does this include vows that could have been annulled before Shabbat and the person just didn't take care of it? A proof is brought from a story that it can still be done. Rav Yosef didn't want to allow people to annul in front of three men on Shabbat as this has the semblance of a court, which cannot convene on Shabbat. However, Abaye showed that since so many elements necessary for a court are not necessary for annulling vows, it does not have the semblance of a court. What are all those elements? Can one nullify vows at night? Another story is told of one who was reprimanded by the rabbis when he came to annul his vow that he is a sinner for taking vows in the first place. What wording can/cannot be used to nullify a wife's/daughter's vow? How does the wording need to be different on Shabbat? Why? What if the wording used for nullification was switched to the wording used to annulment or vice-versa?
