Brides and grooms always want their wedding to go off without a hitch. But they also want money left over for their honeymoon, home and family, all of which could come after. And that's why more couples are opting for September and October weddings rather than the traditional June date, according to an annual survey by TheKnot, a website devoted to weddings. June weddings dominated until 2014, when September had matched it. But by 2016, September and October became more popular months to tie the knot.
