The patrons of Quinzano d'Oglio are Saints Faustinus and Jovita, celebrated on 15 February in the Church of Santi Faustino e Giovita.
In November, the cooked salami and pork crackling fair is held, in an area where agriculture, and in particular maize monoculture, has always played a leading role in the local economy. The town also holds the Parco Oglio Nord.
