Tuesday may be a fine day to get married but there are no traditional Jewish sources that deem Tuesday as the ideal day. There has never been a particular day of the week deemed as THE Jewish wedding day. Jewish weddings have occurred on Friday afternoon, Sundays, Wednesdays as well as Tuesday. Traditionally, weddings do not occur on the Sabbath (from sunset Friday until sunset Saturday) because historically Jewish weddings involved a monetary transaction and the signing of a legal document, both activities prohibited on the Sabbath. Another reason for not marrying on the Sabbath can be found in the midrash. Jewish weddings are not celebrated on the Sabbath or other Jewish holidays "because we do not mix one simcha or joyous occasion with another." To paraphrase, "Why not hold your wedding when its joy alone will be celebrated?" In contemporary North America, there are Jewish weddings held on Saturday evenings now to accommodate traveling family and guests.
Whatever day you choose for your wedding, may every wedding day be "ki tov" / good!
Blessed is the creation of joy and celebration, lover and mate, gladness and jubilation, pleasure and delight, love and solidarity, friendship and peace. Soon may we hear the world rejoice and celebrate all loving relationships.
