The patrons of Aiello del Sabato are Saint Sebastian and Saint Fabian, celebrated on 20 January.
Since 2003, on the first weekend of September, the town hosts the Fiano Music Festival, a wine-and-food event pairing music with tastings of Irpinia's traditional wines, starting with Fiano di Avellino DOCG, produced by the area's best wineries. The town also holds Palazzo Ricciardelli and the Chiesa Madre di Santa Maria della Natività.
