The season traditionally begins in the Real Maestranza Bullring on Easter Sunday, continuing before and after the April Fair, for up to 16 to 18 days. There are also bullfights around the feast of Corpus Christi; on August 15 - feast of the Assumption as well as Virgen de los Reyes, patroness of Seville; the last week-end in September, feast of St. Michael and on October 12, the feast of Virgen del Pilar when the season officially comes to an end, though there may well be a few more bullfights. Furthermore, there are novilladas (bullfights with young bulls) and picadors during all Sundays in May, June and September. In July and August there may well be some further novilladas with picadors and, particularly, a promotion series without picadors, sponsored by the Real Maestranza which has established several prizes for the best performances.
