The Metropolitan Opera is the largest classical music organization in North America. It presents about 27 different operas each year in a season which lasts from late September through May. The operas are presented in a rotating repertory schedule with up to seven performances of four different works staged each week. Performances are given in the evening Monday through Saturday with a matinée on Saturday. Several operas are presented in new productions each season. Sometimes these are borrowed from or shared with other opera houses. The rest of the year's operas are given in revivals of productions from previous seasons. The 2012-13 season comprised 209 performances of 28 operas.
