Era Fascista

The March on Rome, or more precisely the accession of Mussolini as prime minister on 29 October 1922, is day 1 of Anno I of the Era Fascista.

[4] Era Fascista dates often consisted of the Gregorian date followed by the corresponding Era Fascista year in Roman numerals, as part of Fascist propaganda's appropriation of ancient Roman iconography.

The Era Fascista year was sometimes written as "Anno XIX", "A. XIX", or marked "E.F."[5] The calendar was intended to replace the "bourgeois" Gregorian calendar in Italian public life to the extent that, in 1939, newspapers were forbidden to write about New Year's Day.

[6] The tenth anniversary of the March on Rome, Anno X, was called the Decennale (evoking the ancient Roman Decennalia).

[7] The calendar was abandoned in most of Italy with the fall of the Fascist regime in 1943 (Anno XXI), but continued to be used in the rump Republic of Salò until the death of Mussolini in April 1945 (Anno XXIII).
