The Taz 551:17 agrees to be lenient based on the concern that perhaps if you don’t make the Bracha now you may not be able after the Ben HaMeysarim.

  16. The Gemara in Taanit 26b says that one shouldn’t cut one’s hair the week of Tisha BeAv. This Gemara is brought as Halacha by the Rambam (Taaniot 5:6). The Ramban (Torat HaAdam (Aveilut Yishana pg 346) explains that this prohibition applies to all hair on the body except the mustache if it interferes with eating. The Tur and S”A 551:3,12-13 rule like the Ramban that during the week of Tisha BeAv one is forbidden to cut any hair on one’s body except if there’s facial hair interfering with eating. Chazon Ovadyah (Arba Taniyot pg 158) writes that this is Sephardic custom. However, Rama 551:4 rules that Ashkenazim should be strict not to cut hair all three weeks like the Sefer Minhagim (pg 74).

Mishna Berura 551:81 and Shaar Hatziyun 551:91 as well as the Chayei Adam 133:18 bring two reasons that children should be included based on the Terumat Hadeshen 142. One being chinuch, in which case it would only apply to older than six and the other being "agmat nefesh," meaning it makes people feel more pain to see children mourning, in which case it would apply to even children under 6.
  24. Eliya Rabba 551:7, Sharei Tshuvah 551:12, Mishna Berura 551:20, Aruch Hashulchan 551:15
  25. Since S”A 551:12 rules that it’s forbidden to cut any hair on one’s body during the week of Tisha BeAv as a din from the Gemara it would seem clear that it’s forbidden to shave during the week of Tisha BeAv. Additionally, Ashkenazim who follow the Rama shouldn’t be able to shave during the entire three weeks as Rama 551:4 writes that the minhagim of the week of Tisha BeAv apply to the entire three weeks. However, there are several leniencies in the Achronim.
    • (1) Shaving Regularly: Magan Avraham 551:14 explains that the reason the Rama is strict by cutting hair all three week and is lenient by washing clothes (that it should only begin from Rosh Chodesh Av) is because it wasn’t common to cut hair every week. This Magan Avraham is brought by the Achronim including the Chaye Adam 133:17, and Mishna Brurah 551:32. Additionally, Aruch HaShulchan 551:16 explains that it takes 3 weeks of not cutting hair to make it recognizable that one is in mourning. Based on this, Shearim Metzuyanim BeHalacha 122:5 says that those who usually shave every 2-3 days should be able to shave since for them it’s just like washing clothes. Rav Ovadyah in Chazon Ovadyah (Vol Arba Taniot pg 162) based on this M”A says that seemingly, Ashkenazim should be allowed to shave for Kavod Shabbat prior to the week of Tisha BeAv. However, Sh”t Shaar Zekenim pg 88a (quoted by Kaf HaChaim 551:65), Shivilei Dovid 551:4, and Rav Vozner in Sh”t Shevet HaLevi 10:81:3 reject this leniency based on the minhag to be strict for all circumstances.
    • (2) Uncomfortable: (a) Rabbi Elazar Melamed in Peninei Halacha (zmanim pg 154-5) writes that if a person shaves everyday it’s very uncomfortable not to shave and it’s similar to S”A 551:13 that permits shaving a moustache that interferes with eating. (b)Rav Soloveitchik (quoted by Nefesh HaRav, Rav Schachter pg 191 and Shiurei Harav Al Inyanei Aveilut V'Tisha B'Av, pages 20-21 compared the three weeks to the Avielut of a year, the week of Tisha BeAv (or according to Ashkenazim, from Rosh Chodesh) compares to the Avielut of Shloshim, and Tisha BeAv itself is like Avielut of Shiva. Accordingly, Rav Shechter writes that one who regularly shaves everyday would be allowed to shave everyday until Rosh Chodesh Av. (Rav Shechter supports this comparison from Sh”t Panim Meirot 3:37e, and goes so far as to question Sh”t Igrot Moshe Y”D 2:137 who compares the week of Tisha BeAv to Avielut of Shiva.)
    • (3) Shaving Specifically: Seemingly, from S”A 551:12 all bodily hair can’t be cut including shaving a beard. However, Sh”t Chatom Sofer Y”D 348 D”H VeIy Galach writes that the entire prohibition only applies to cutting one’s hair but the poskim never spoke about shaving facial hair. This chiluk is also made by the Sh”t Nodeh BeYehuda O”C 14. Shearim Metsuyim BeHalacha 122:5 brings these achronim as halacha for someone who needs to shave for work.
    • (4) Monetary loss: (a)Sh”t Maharam Shik Y”D 371 writes that there is what to defend those who it’s difficult to do business with important people without shaving and during the year they regularly shave every 2-3 days to continue in the three weeks until the week of Tisha BeAv. (b) Sh”t Igrot Moshe C”M 1:93, O”C 4:102, 5:24:9 writes that by loosing a business deal or customers that will effect one’s income after Tisha BeAv, one can shave until the week of Tisha BeAv, but during the week of Tisha BeAv itself it’s only permissible to shave if one will not be able to make an income after Tisha BeAv or without working one needs to borrow money and it’s difficult to find someone to borrow from). (c) Maadenei Shlomo pg 51 brings Rav Shlomo Zalman Auerbach who says that if there’s a chance you’ll loose you’re job you can shave (even during the week of Tisha BeAv). Halichot Shlomo pg 414 brings Rav Shlomo Zalman Aurbach who says that it’s permissible for a person who is endanger of losing a lot of money or his job may shave during the three weeks. (d)Shearim Metsuyim BeHalacha brings the Taz 551:1 (brought by Mishna Brurah 551:12) that says nowadays we don’t decrease our business activity during this time since we have to pay government taxes and all income is included in our Parnasa and therefore here too if there’s a chance of losing Parnasa that can be considered a concern of loss of money.
    • (4) Kavod Shabbat: (a) Magan Avraham 551:14 and Mishna Brurah 551:32 write that the prohibition of cutting hair applies even for Kavod Shabbat (unlike laundering which is relaxed for Kavod Shabbat for someone who doesn't have other clothes, because people don't cut their hair either way weekly). Yet, Pri Megadim (A”A 551:14) writes that according to Rama one can shave in honor of Shabbat until Rosh Chodesh Av. However, Mateh Yehuda 551:4 writes that even in honor of Shabbat one can’t shave during the three weeks. (b) On this dispute, Kaf HaChaim 551:66 writes that in this regard in depends on the minhag of the place (to follow the Pri Megadim or not), and Rabbi Moshe Karp in Hilchot UMinhagei Ben HaMeysarim (pg 25) writes that the Pri Megadim was more in line with minhag Ashkenaz than the Mateh Yehuda and there’s a lot to rely on to follow Pri Megadim. (c) Even on the original position of the Magan Avraham, the Hagot Rabbi Akiva Eiger and Buir Halacha 551:3 D”H VeChen (based on Tosfot Tanit and the Yerushalmi) argue that cutting hair should be permissible for Kavod Shabbat even for Shabbat Chazon. [However, the Rishonim themselves don’t all agree with Tosfot including the Kol Bo (quoted in Bet Yosef 551:4) who wouldn’t shave before Shabbat chazon and the Bet Yosef (who argues on Tosfot that it’s impossible to think that it’s permissible to cut hair on Tisha BeAv for Kavod Shabbat).] (d) Ashkenazim: Sh”t Ner Ezra (vol 2 pg 155-8) concludes that one can be lenient to shave for Kavod Shabbat and quotes Rav Aharon Lichtenstein who agrees. Weekly Parsha Halacha by Rabbi Neustadt writes that since many do shave regularly (more than once a week) there is a basis for the lenient minhag (based on the logic of the Magan Avraham). Nonetheless, the Shemirat Shabbat KeHilchata 42:52 writes simply like the Mishna Brurah not to shave during the three weeks even for Kavod Shabbat. (e)Sephardim: Rav Ovadyah Yosef (Sh"t Yachava Daat 3:39, Sh”t Yabea Omer 3:31:5; Chazon Ovadyah pg 162) writes that there is what to rely on to shave Friday of Shabbat Chazon if ones beard is uncomfortable, and certainly there’s what to rely on for Ashkenazim to shave for Kavod Shabbat during the rest of the three weeks. (e) Someone in doubt: Rabbi Robinowitz (quoted in Peninei Halacha by 156) says that a person should follow the minhag of his father so as not to appear more lenient or strict that his father.
  26. Magan Avraham 551:10 says that it is forbidden to dance during the three weeks. This is brought as Halacha in the Achronim including Eliya Rabba 551:6, Baer Hetiev 551:11, Mishna Brurah 551:16, Yalkut Yosef (Moadim pg 560, Kitzur S”A 551:9), and Chazon Ovadyah (Arba Taaniyot pg 149).
  27. Sh”t Mishna Halachot 6:109 permits dancing at a Sheva Brachot during the three weeks. Sh”t Mishna Halachot quotes that Rav Moshe Feinstein also permitted, while Rabbi Tzvi Mieslish forbade. (see Sh”t Igrot Moshe E”H 1:97.) Sh”t Avnei Yishfa 1:112 and Chazon Ovadyah (Taniot pg 153) agree with Mishna Halachot to allow dancing. However, Rav Vosner in Sh”t Shevet HaLevi 3:157 writes explicitly that for a simcha of Sheva Brachot music and dancing are forbidden.
  28. Sh"t Teshuvot VeHanhagot 2:263, Piskei Teshuvot 551:46 Rabbi Ayreh Lebowitz, Moadei Yeshurun (pg 128) quoting Rav Moshe, Halichot Shlomo (Moadim, vol 2, chap 14, note 7), MeBayit Levi (vol 13, pg 22, note 5) quoting Rav Wosner, Sh"t Rivevot Ephraim 3:333, 4:135:14, 6:285:2, and Shevet HaKehati 1:169:4. Rabbi Eider quotes Rav Moshe Iggerot Moshe Even Haezer 4:84 who says even during the nine days if one is sweating or dirty and wants to wash off it's permissible to dip in the pool for a short time. Shaarim mitzuyanim bihalacha kuntres acharon 122:12 is lenient with children swimming in private area during the nine days, but not in public, like camps.
  29. Rambam Hilchot Taaniot 5:6 says from the week of and the Mordechai Taanit 639 says from Rosh Chodesh Av. Both opinions are quoted in S"A 551:16. Kaf Hachayim 551:186 says to follow whatever the custom of the place where you are living.
  30. Aruch Hashulchan 551:37
  31. S”A 551:17 based on Maharil 31 writes that one should refrain from saying Shehecheyanu during Ben HaMeysarim. The Magan Avraham 551:42 explains that the reason not to make Shehecheyanu is because the three weeks is a time of tragedy for Klal Yisrael and it’s improper to have extra joy. However, the Gra D”H VeNohagin understands the practice as based on Aveilut and therefore argues that this is only an extra chumra and one is allowed to make Shehecheyanu (just like a mourner can make a Shehecheyanu as in Brachot 59b). The Taz 551:17 agrees to be lenient based on the concern that perhaps if you don’t make the Bracha now you may not be able after the Ben HaMeysarim. Mishna Brurah 551:98 concludes that one shouldn’t be lenient except on Shabbat.
  32. Mishna Brurah 551:99
  33. Sefer Chasidim 840, Mateh Moshe 697, Yosef Ometz 861, Magan Avraham 551:21,42, Chaye Adam 133:8, Kitzur Shulchan Aruch 122:2, Sh"t Yechave Daat 1:37 permit making Shehecheyanu on Shabbat. However, the Magan Avraham 551:42 quotes the Kitvei HaArizal who is machmir even on Shabbat. Mishna Brurah 551:98 concludes that one can be lenient regarding making Shehecheyanu on Shabbat since there’s some are lenient on shechiyanu during all of the three weeks and there’s some who specifically permit Shabbat.
  34. Eliyah Rabba 551:17 in name of Madenei Yom Tov that one should wear new clothes even on Shabbat during the three weeks because wearing new clothes has a special aspect of happiness (greater than eating a new fruit). So holds the Chaye Adam 133:14, Derech HaChaim 551:6 and Kitzur Shulchan Aruch 122:2 not to wear new clothes all three weeks including Shabbat. However, Aruch HaShulchan 551:38 writes that one can make Shehecheyanu before Rosh Chodesh Av and afterwards one shouldn’t make Shehecheyanu even on Shabbat Chazon. Additionally, Mishna Brurah 551:45 writes that even those who are lenient to make Shehecheyanu on Shabbat will agree to be strict on Shabbat Chazon not to wear new clothes (which has a special element of happiness that a new fruit doesn’t have). Sh”t Yechave Daat 1:37 and Torat HaMoadim 5:7 concurs to the opinion of Mishna Brurah.
  35. Sh”t Sh”t Chaim Shal 1:24, Kaf HaChaim 551:207, Sdei Chemed 5:page 277, Biur Halacha 551:2 and Ikrei HaDaat O”C 27:9 write that one shouldn’t say Shehecheyanu on the night of Sheva Aser BeTamuz. However, Nechamat Yisrael (pg 40) permits in case of great need based on Sh”t Igrot Moshe O”C 1:168 (so is explicit in Sh”t Igrot Moshe O”C 3:100) and Mishnat Yacov (pg 168) permits Shehecheyanu at night even without any need.
  36. Nitai Gavriel 17:19 based on Maharil 31 who says the restriction of saying shehecheyanu is only on a beracha that can wait until after.
  37. Sh”t Chaim Shal O”C 7 and Ketonet Yosef 11 (quoted in Kaf HaChaim 551:207) writes that even though one can’t make a Shehecheyanu during the 3 weeks, one can eat a new fruit or wear new clothes without a Bracha. However, the Sefer Chasidim 840, Shaarei Knesset HaGedolah 551:52, Bach 551e, Maamer Mordechai 551:14, Yometz Ometz 56, Bear Heitev 551:20, and Kitzur Shulchan Aruch 122:2 write that one is not allowed to have a new fruit during the three weeks without a Bracha, since having a new fruit requires a Bracha and it can’t be made during the three weeks.
  38. Halichot Shlomo pg 411 brings from the Talmidim of Rav Shlomo Zalman Aurbach that it’s permissible to buy new clothes since nowadays we don’t make a Bracha on buying clothes. see Nechamet Yisrael pg40
  39. Sh”t Kapei Aharon 52 writes that it’s clearly forbidden to listen to music during the three weeks. This is brought in Sh”t Igrot Moshe 1:166. Nitai Gavriel 15:1 writes that this law is missing from S”A and early poskim because there’s a general prohibition of Listening to Music and so there was no question about the three weeks. [There is a hint to the prohibition in the Pri Megadim and Maharam Shik who discuss playing music for an income during the three weeks.] However, because many are lenient like the Rama (unlike S”A and Bach) and are lenient regarding music all year, this question became relevant and it’s unanimously accepted by contemporary poskim that music is forbidden during the three weeks because it brings with it simcha just like dancing (explicitly forbidden by Magan Avraham 551:10). See next notes.
  40. Sh"t Tzitz Eliezer 16:19. Kaf Hachayim 551:41 writes that preferably it should not be done, and even if one is lenient it should only be sad songs. The Pri Megadim Esehl Avraham 551:10 writes that parallel to the concept of davar ha'aved on chol hamoed, the rabbis permitted somebody who needs to dance or play music for livelihood may do so.
  41. Yalkut Yosef (Moadim, 5748 edition, pg 554), Nitay Gavriel 15:1, Penieni Halacha (pg 144), Sh"t Iggerot Moshe OC 1:166 and 3:87 Torat Hamoadim 5:2, Sh”t Yachave Daat 6:34 and 3:30, Chazon Ovadyah (Arba Taniyot pg 151), and Rabbi Mansour in Daily Halacha hold that recorded music is forbidden during the three weeks. See also Sh"t Igrot Moshe YD 2:137, Minchat Yitzchak 1:111, Shalmat Chaim 29:1, Mishnat Sachir 2:145, Sh”t Ohel Yisachar 39, and Divrei Shalom 3:118.
  42. Mekor Chaim 551:1 and Or letzion 3:25:2 write that during the 9 days one shouldn’t listen to even vocal music. This is brought as halacha in the Halachot UMinhagei Ben HaMesarim (by Rabbi Moshe Karp pg 25) and Nachmat Yisrael 3:3. Chazon Ovadyah (pg 151-4) and Torat Hamoadim 5:2 are lenient with vocal song that are praise to Hashem (especially for Shabbat including Shabbat Chazon).
  43. Mekadesh Yisroel (pg 20), Chut Shuni (Shabbat, vol 2, pg 325), Sh"t Shevet HaLevi 3:15, Halachically Speaking (Vol 5, Issue 13, note 46)
  44. Sh”t Shevet Halevi 6:69, 8:127:2, Nitai Gavriel 15:1, Sh”t Tzitz Eliezer 15:33, Piskei Shemuot (pg 54) quoting Rav Elyashiv and Rav Karlitz, and Nechmat Yisrael 3:4 forbid listening to a recorded vocal song. However, Sh”t Igrot Moshe YD 2:137 and Sh”t Yachave Daat 6:34 permit (regarding Jewish music). Halachically Speaking quotes Rav Yisrael Belsky and Rav Efraim Greenblatt who forbid listening to singing which is meant to simulate actual music such as A capella because it creates the same musical experience. Rabbi Aryeh Lebowitz writes that most permit listening to recorded voices singing.
  45. In general, Rama (551:3) permits music for a dvar mitzvah like a wedding. However, the Yavetz in his siddur (Amudei Shesh; quoted by Yafeh Lelev 560:7) writes that a simcha of a Brit Milah there should be no music. Eliyah Rabba 551:26 writes that the minhag is like the Yavetz. Regarding the three weeks Chida in Sh”t Chaim Shal 1:21 writes that the (Sephardic) minhag is to be lenient to have music at a meal of a Brit Milah. Ikrei HaDaat (Y”D 36:23), Sh”t Maaseh Avraham (Y”D 48), Moed Kol Chai (10:20), Ot Chaim VeShalom (the Munchatch Rebbe; 265:29), Torat HaMoadim 5:4, and Sh”t Yachave Daat 1:45 write that the Sephardic minhag is to lenient by the meal of a Brit Milah. (It seems that Shirei Knesset HaGedolah 551:33 who’s strict regarding the party for a Milah at night, but would agree concerning the meal right after the Milah. Additionally, it seems Sh”t Igrot Moshe 1:166 would agree as he even discusses a tzedaka banquet regarding music the rest of the year.)
  46. Sh”t Yachave Daat 1:45 writes that music is permited for a seudat mitzvah including a siyum. Torat HaMoadim 5:4 and Yalkut Yosef (Moadim, 5748 edition, pg 554) extend this to even during the three weeks.
  47. Sh”t Yachave Daat 1:45 permits music at a suedat mitzvah such as a Pidyon HaBen. Torat HaMoadim 5:4 and Yalkut Yosef (Moadim, 5748 edition, pg 554) extend this to even during the three weeks.
  48. S"A 551:17
  49. Sh"t Yachava Daat 6:34, Yalkut Yosef (Moadim, 5748 edition, pg 554), and Torat HaMoadim 5:4 permit music at a simchat Bar Mitzvah during the three weeks. However, Darkei Horah (Dinei Ben Hametsarim pg 17, by Rav Asher Weiss) and Natai Gavriel (Ben HaMetzarim chapter 16:3) forbid. Halichot Emet 7:12 writes that the sephardic minhag is to be lenient and ashkenazic minhag is to be strict. Halachically Speaking writes that some are lenient.
  50. Sh”t Igrot Moshe O”C 166 permits all types of festivities of mitzvah and says that perhaps even a tzadeka banquet perhaps can be included. However, the Sh”t Igrot Moshe concludes that during the three weeks we are more strict regarding music and therefore there is almost nothing to rely on to play music at a tzedaka banquet.
  51. Sh”t Mishna Halachot 6:107, Sh”t Yachave Daat 6:34, Torat HaMoadim 5:2, Sedei Chemed (Peat Sadeh, Ben HaMetsarim 1:10),

  53. The gemara Baba Batra 60b quotes the opinion of Rabbi Yishmael Ben Elisha that after the destruction of the Beit HaMikdash, it would have been appropriate for the rabbis ban eating meat and drinking wine in order to properly mourn. However, since most of the congregation would not be able to abide by this, the rabbis never made it. Biur HaGra, OC 551:9, writes that this is the source for refraining from eating meat and drinking wine prior to Tisha B'Av that although it is impossible to ban eating meat and drinking wine throughout the year, it is possible to refrain from meat and wine for a short period of time.The Mishna in Taanit 26b the Gemara 30a discuss the prohibition of eating meat during the seudat hamakseket prior to tisha b'av. Rambam Hilchot Taaniot 5:6 says that the custom is to extend the prohibition beyond that meal. He says that some don't eat meat during the week of tisha b'av, and some don't eat from rosh chodesh av and onward. S"A 551:9 writes that there are three customs about not eating meat and drinking wine; some refrain only for the week on Tisha BeAv, some refrain for the nine days (from Rosh Chodesh Av), some refrain for the whole three weeks. Mishna Brurah 551:58 writes that the Ashkenazic custom is not to eat meat or drink wine for the nine days including Rosh Chodesh Av but excluding Shabbat (Mishna Berura 551:59). This is also written in the Weekly Halacha by Rabbi Neustadt. Sh"t Yachava Daat 1:41 writes that the Sephardic custom is to refrain from eating meat and wine during the nine days, however, on Rosh Chodesh the minhag is to be lenient, however, some are strict. See also Chazon Ovadyah (Arba Taniyot pg 169) and Halachot and History of The Three Weeks (by Rabbi Shlomo Churba, pg 37) who also write that the Sephardic custom is not to eat meat, poultry or wine in the nine days.
  54. Chazon Ovadyah (Arba Taniyot pg 177) writes that there is what to rely on, while the Weekly Halacha by Rabbi Neustadt quotes Sh"t Igrot Moshe 4:21(4) who forbids (see there).
  55. Chazon Ovadyah (Arba Taniyot pg 196-7)
  56. Chazon Ovadyah (Arba Taaniyot pg 196-8). Although the Rama 551:10 writes that one should minimize the amount of guests invited to this meal, Rav Moshe Feinstein and Rav Shlomo Z. Auerbach (cited in Nitei Gavriel Hilchot Bein HaMetzarim 41:4), rule that if the one who completes the masechet eats in a communal dining room (such as a camp or hotel), all those who eat with him may participate.

  58. MB 551:70 and Shaar Hatziyun 551:76 say that although there is no requirement for the child to mourn for the beit hamikdash, the prohibition of feeding children prohibited items discussed in SA OC 343 extends to things that are only prohibited by custom. Iggerot Moshe 4:21:4 says even to feed the children meat on Friday afternoon before shabbat would not be allowed unless they usually eat their Friday night meal at that hour. Based on the Magen Avraham 551:31, Rabbi David Yosef in torat hamoadim Siman 5 page 190 says there is ample room to be lenient in this case. Aruch Hashulchan 551:26 as well says there is room to be lenient, especially in a case where it is a weak child who can gain a lot from eating the meat.
