The patrons of Lonate Ceppino are Saints Peter and Paul, celebrated on 29 June in the Church of Santi Pietro e Paolo.
In the past, every July, the town's districts competed in a palio, a playful-sporting event; between 1948 and the late 1960s, population growth led to its suppression. The town's other patron, the Blessed Virgin Mary of the Rosary, is celebrated on the second Sunday of October.
