Q. I’ve heard that we should preferably abstain from making weddings on Chesvan is that true? Should one change the wedding date?

A. There are Poskim who maintain that one should avoid being wedded on Marchesvan, (Lev Chaim 2: 26, Sdei Chemed – Maareches Chassan Vekallah 23, who also mentions that this was the Yerushalaim and Kushta traditions, Segulos Yisroel – Maareches Nissuin 31, Minchagei Chabad p.76. Nitei Gavriel – Nissuin 1: 48: 14, who additionally quotes different Chassidic traditions)
However, many others assert that there is no issue at all on getting married on Marchechvan (Shulchan Haezer p. 61, Betzel Hachochma 2: 60, Divros Eliahu 6: 70 et. al.) Sdei Chemed (ibid.) quotes also various permissive sources and mentions that the Chassam Soffer married Rabi Akiva Eiger’s daughter on this month. Nitei Gavriel (ibid.) also quotes many other Chassidic traditions who would perform marriages on this month, such as Tsanz, Belz, Tzeilem, and others.
Horav Shlomo Miller’s Shlit’a opinion is that one should follow the traditions of the community he belongs to and his family minhagim.
