The Blessing of Shehecheyanu During the Three Weeks.

Is it permissible to recite the blessing of Shehecheyanu during the Three Weeks?

During the Three Weeks, the blessing of Shehecheyanu is not recited. However, if the fruit will spoil or will not be available after Tisha B'Av, it is permissible to recite the blessing. On Shabbat and Yom Tov, it is permitted to recite Shehecheyanu.

It is written in the Shulchan Aruch, Orach Chaim, Siman 551, Se'if 17: "It is good to avoid saying Shehecheyanu during the Three Weeks on a fruit or garment, but on the redemption of the firstborn, it is said, so as not to miss the mitzvah." The Rema writes: "Also on a fruit that will not be found after Tisha B'Av, it is permissible to bless and eat it during the Three Weeks." The Mishnah Berurah, Se'if Katan 98, writes: "Even though Shehecheyanu is recited in mourning, during these days, since it is a time of calamity, it is not appropriate to say Shehecheyanu for this time. The Gaon Rabbi Eliyahu, in his commentary, disagrees with this and writes that it is an excessive stringency, and also the Taz questions this. Therefore, on Shabbat, one should not be stringent in this matter. Many later authorities agree to be lenient on Shabbat." Sha'ar HaTziyun, Se'if Katan 99, writes: "The Gaon Rabbi Akiva Eiger, in his innovations, brings in the name of the book Beit Yehuda that on Rosh Chodesh, the rule is the same as on Shabbat."
