Jackie Robinson Day is celebrated every year on April 15th in honor of the day in 1947 when Jackie Robinson made his debut in Major League Baseball with the Brooklyn Dodgers, breaking the color barrier in the sport. Robinson became the first African American player in the modern era to play in the major leagues, paving the way for future generations of Black athletes in professional baseball and other sports.

Jackie Robinson Day is a time to celebrate Robinson's contributions to the game of baseball, as well as his role in the civil rights movement. Players across the MLB wear Robinson's iconic number 42 on their jerseys on this day as a tribute to his legacy. The day also serves as a reminder of the ongoing fight for racial equality and social justice in sports and society as a whole.
