Opening Day is the day on which professional baseball leagues begin their regular season. For Major League Baseball and most of the minor leagues, this day typically falls during the first week of April. For baseball fans, Opening Day serves as a symbol of rebirth; writer Thomas Boswell once penned a book titled, Why Time Begins on Opening Day. Many feel that the occasion represents a newness or a chance to forget last season, in that all 30 of the major league clubs and their millions of fans begin with 0–0 records.
