Twins Days Festival takes place from August 05 till August 07, 2022. It is celebrated each year on the first full weekend of August in Twinsburg, Ohio. Twins Days Festival is the largest annual gathering of biological twins and other multiples (e.g. triplets, quads) in the world. It was founded in 1976 by Revco's Charles R. DeHaven.
The event has twin based contests, "talent" shows which is opened every year with the Star Spangled Banner sung by John and Jerry Starlet and signed in ASL by Jamie Maassen and Jodie Qualkinbush, and a parade along Ravenna Road and routinely draws thousands of participants from all over the United States.
A twin is one of two offspring produced in the same pregnancy. Twins can either be monozygotic ("identical"), meaning that they develop from one zygote that splits and forms two embryos, or dizygotic ("fraternal") meaning that they develop from two eggs, each fertilized by separate sperm cells.
