Twins Days Weekend is the first full weekend in August every year. People will see double in Twinsburg, Ohio during the Twins Day Festival. Guinness Book of World Records calls it the “Largest Annual Gathering of Twins in the World.”

The goal of the Twins Days Festival is to celebrate the uniqueness of twins and others of multiple births. Researchers attend the festival because it provides a centralized location for a multitude of twin-related information, including research studies and photo documentation of twins.

Moses and Aaron Wilcox, who founded Twinsburg, Ohio in 1819, inspired the creation of Twins Days. In 1976, during the Bicentennial Celebration of the United States, people in Twinsburg started planning to set aside one day a year for twins. The following year, determined not to let the idea die, a committee went into action and made the second Twins Day happen. There were 38 sets of twins who attended that year.

The past 43 festivals have seen over 77,000 sets of twins and multiples attend.
