Even if you're not heading to the movies on Monday or Tuesday, you'll be seeing "42" if you're a Major League Baseball fan. All players and on-field personnel will once again don the No. 42 in honor of Jackie Robinson Day on Monday and Tuesday to mark the 66th anniversary of the Dodger legend's breaking of the color barrier in baseball in 1947. MLB has celebrated Robinson's landmark debut every year since 2004.

Every MLB ballpark will commemorate Robinson's historic debut with on-field ceremonies prior to games on Monday and Tuesday. Special bases and lineup cards will be used and a designated video clip will be shown at all ballparks. Robinson's daughter, Sharon, will visit students in Pasadena, Calif. on Monday morning for a discussion on her book, "Jackie Robinson: American Hero." Fittingly, the Robinson family will take part in a celebration at Dodger Stadium in Los Angeles on Monday night.

"We are particularly proud that through the efforts of MLB and the movie "42," a new generation will not only learn about Jack, but it will also spark them to think about what they can do in their lives to make significant differences in their own communities," said Rachel Robinson, the widow of Jackie Robinson.

The Robinson biopic, "42," opened at No. 1 at the box office this weekend. Meanwhile, several programs were held in greater Los Angeles on Saturday and Sunday to help deliver the message of Reviving Baseball in Inner Cities (RBI), a program focused on developing the love of baseball among inner city youths. The MLB Network also aired special Robinson-related programming over the weekend.

The custom Instagram page Iam42.com will act as a photo aggregator where fans can share their feelings on Robinson's legacy. The page has already been populated with stirring photographs. MLB.com will collect the video clips and events from the ballparks. Monday's game between the Philadelphia Phillies and the Cincinnati Reds at Great American Ballpark will serve as ESPN's national broadcast to commemorate the event.
