Jackie Robinson Day takes place on April 15, 2020. Jackie Robinson Day is a traditional event which occurs annually in Major League Baseball, commemorating and honoring the day Jackie Robinson made his major league debut.
Initiated for the first time on April 15, 2004, Jackie Robinson Day is celebrated each year on that day. The festivity is a result of Robinson's memorable career, best known for becoming the first black major league baseball player of the modern era in 1947. (With material from: Wikipedia)
