On average about 1,000 couples get married each day in Las Vegas. But on Friday more than 3,200 are expected to tie the knot.
"We talked about 10/10/10 or 12/12/12, and 11/11 seemed to be the right timing for us," said Samantha Stokes, who flew with her fiancé Jonathan Barron to Las Vegas from Maryland.
Some 1,000 ethnic Chinese couples exchanged vows across Malaysia on a date viewed as auspicious and romantic. In China, a special "1111" train started at 11:11 a.m. on the No. 11 line in Shanghai.
"The numbers rhyme with one husband, one wife and one soul in Chinese and signifies a marriage that would last a lifetime," said one newlywed.
According to David's Bridal, Los Angeles ranks at the top for brides registered. Over 700 L.A. brides are said to be getting married on Friday.
