Las Vegas wedding chapels were seeing a spike in traffic as couples tried to land a memorable 11/12/13 wedding date.

The Clark County clerk’s office issued 1,399 marriage licenses in the four days leading up to that Tuesday. That was a 28 percent increase from the same four-day period the previous year.

Clerk Diana Alba says the number of licenses is nowhere near what it was during the record-breaking days before July 7, 2007, when the calendar turned up lucky triple sevens.

But she says couples tend to gravitate toward dates like 11/12/13 that are easy to remember, or that fall near a three-day weekend.

Unusual weddings around Sin City on November 12 included a couple who got married on a motorcycle, and another pair who had a six-tier wedding cake made out of hamburgers.
