Elvis Presley impersonator Michael Conti sings as he officiates a wedding for Phoebe Kim and Colton Sorensen of California as they dance at the Little White Wedding Chapel on December 31, 2023 in Las Vegas, Nevada.

The most popular date for Las Vegas weddings was in 2007, when 4,492 couples exchanged vows on July 7, or 7/7/07. Since 1953, more than five million weddings have been held in the city, when the Daily Herald in London published an article referring to Las Vegas as the “Wedding Capital of the World”.
