Opening Day is the day on which professional baseball leagues begin their regular season. For Major League Baseball (MLB) and most of the American minor leagues, this day typically falls during the first week of April, although in recent years it has occasionally fallen in the last week of March. In Nippon Professional Baseball, this day typically falls during the last week of March. 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 is a moment to forget last season, in that all teams begin anew with records. Pre-season exhibition games are usually played in the month before Opening Day, during spring training. A home opener is a team's first game of the season on their home field. Equivalents to Opening Day occur throughout the sport, including minor leagues, college baseball, high school, and youth leagues. Because MLB generally begins its season earlier than the other professional baseball leagues, its Opening Day is the one most commonly recognized by the general public. Most minor leagues start a few days later, but within the same week; the short season Class A and Rookie leagues are exceptions, as they begin in June. College, high school and youth baseball seasons vary widely depending on location and weather conditions. History For generations, Opening Day has arrived amid pageantry. In Cincinnati, home of the sport's first openly all-professional team, the annual Findlay Market Parade marks an official "city holiday" with young and old alike taking the day off to cheer on the Reds. For decades, the first pitch of every major league season officially took place in Cincinnati, and the Reds remain the only major league team to always open the season with a home game (the sole exceptions, since the beginning of the 20th century, being in 1966, when they started the season at Philadelphia after rain washed out the opening series in Cincinnati; 1990, when due to a lockout affecting the schedule they opened the season at Houston; and 2022, when another lockout led to their opening the season at Atlanta). The Chicago Cubs have been the Reds' most frequent Opening Day opponent, visiting Cincinnati for 36 season openers, most recently in 2007. The Pittsburgh Pirates, against whom the current Reds organization played their first opener in 1882, are a close second
