Tanit Bechorot

From Halachipedia

The reason for the fast

  1. In commemoration of the miracle that Hashem saved the firstborn Jews from the plague of the firstborn, the firstborns fast on Tanit Bechorot, which is on Erev Pesach. [1]

Which firstborns are obligated to fast?

  1. A firstborn of one’s mother or the firstborn of one’s father (or both) should fast on Erev Pesach. [2] The reason is that Hashem killed both the firstborns of the father and of the mother in Egypt. [3]
  2. The minhag is that women don’t fast. [4] However, Sephardic women who are firstborn should at least join in a Suedat Mitzvah in order to break the fast if possible. [5]
  3. Even a Levi or Cohen should fast. [6]
  4. A groom within 7 days of the wedding doesn’t have to fast on Tanit Bechorot. [7]
  5. A father should fast in place of his son who is a firstborn but is under Bar Mitzvah. According to the minhag to listen to a Siyum, the father should go to the Siyum in place of his son. [8]
  6. The Rama writes that if the father is a firstborn, the mother should fast for her firstborn son who is under Bar Mitzvah. [9] However, the Mishna Brurah quotes some poskim who say that the father's fast counts for the son as well. Therefore, the Mishna Brurah allows a mother to be lenient if she is in pain. [10]
  7. The Aruch HaShulchan writes that we no longer have the minhag that a parent should fast for a firstborn son who is under Bar Mitzvah. [11]

Those who are unable to fast

  1. One who has an ache in his eyes or head is not required to fast. [12]
  2. If someone will only be able to eat a very small amount because of the fast and won’t be able to fulfill the mitzvot of Matzah and 4 cups of wine, one shouldn’t fast. Nevertheless, it is preferable that he just have snacks and not a meal. [13]

Tanit Bechorim on Friday and Shabbat

  1. If Erev Pesach falls out on Shabbat, some say that one is not obligated to fast while others say that one should fast on Thursday. The minhag follows the latter opinion. [14] The minhag is to do a Siyum on Thursday and exempt oneself from the fast [15], even those who fast Tanit Bechorot regular years. [16] Some say it’s preferable to make a Siyum on Friday in addition to the one on Thursday. [17]
  2. If Erev Pesach falls out on Friday, the fast should take place on that day. [18]

Minhag to join a Siyum

  1. Many are lenient to join in a Siyum and to hear the end of the Maasechet and the Siyum and then join for the Seudat Mitzvah and break the fast the rest of the day. [19]
  2. Some say that it’s critical to understand the last piece of Gemara to join for the Siyum, however, the minhag is to be lenient in any circumstance. [20]
  3. Preferably, after hearing the Siyum one should eat a KeBaytzah of Mezonot or bread as a meal for the Siyum. Some are lenient and allow one to break the fast after hearing a Siyum without eating there. [21]
  4. If one learned an entire Maasechet except for one paragraph, it’s sufficient for a Siyum. [22]
