Il giorno di San Sebastiano (English: Saint Sebastian Day) is an Italian film written and directed by Pasquale Scimeca.

[1] The film is based on true historical events, the Caltavuturo massacre that took place on January 20, 1893, in Caltavuturo in the Province of Palermo (Sicily), during the celebration of Saint Sebastian.

The claim for land reform was one of the demands of the Fasci Siciliani (Sicilian Leagues), a popular movement of democratic and socialist inspiration in 1891–1894.

It is based on a play by Rosario Garibaldi Bosco, one of the leaders of the Fasci Siciliani.

The play, a monologue depicting a peasant woman whose husband was killed in the events at Caltavuturo, was first performed on February 2, 1893, in Palermo to raise money for the victims.
