On 1 May every year Italy dedicates a public holiday to its workers.

In Rome buses and trams will run from 08.30 to 13.00 and from 16.30 to 21.00, with the usual night hour services during the nights either side of the holiday. Rail services to Ostia, Viterbo and Giardinetti will follow festive timetables.

The city's metro lines will operate from 05.30 until 01.30, although the Manzoni and S. Giovanni stations on the A line will close at 15.00, coinciding with Piazza S. Giovanni's traditional May Day concert organised annually by the main Italian trade unions. The area around Piazza S. Giovanni will be closed to traffic from 08.30 on 1 May until around 05.00 the next morning, once the city's refuse collectors Ama finish clearing the streets.

The eight-hour concertone line-up features Elio e Le Storie Tese, Max Gazzé, Cristiano De André, I Ministri, Africa Unite e Marta sui Tubi, Motel Connection, Enzo Avitabile and i Bottari, Management Del Dolore Post Operatorio and Marco Notari.

A number of Italian actors such as Valeria Golino, Riccardo Scamarcio, Jasmine Trinca and Emanuela Grimalda will read texts dedicated to the theme of work.

One performer who will not be entertaining the crowds is rapper Fabri Fibra who concert organisers dropped at the last minute over some of his controversial lyrics which critics say glorify violence against women.

This year the event will be recorded in a "social movie" filmed by audience members themselves through a free iPhone and Android app. Concert-goers can make their own 15-second video of the concert, at any time of the day, even including their journey to and from the concert. The mini-films are designed to detail the concert experience and will be assembled in a feature film called “One million eyes, baby" by director Stefano Vicario.

The theme of this year’s event is “La musica per il nuovo mondo - Spazi, radici, frontiere” and it will be screened live on Rai Tre from 15.00-19.00 and from 20.00 until midnight.

On the morning of 1 May, around 1,000 people are expected to participate in the hour-long “Lavoro...in corsa” marathon, departing from Via Carlo Felice at 10.00. During this time there will be disruptions to public transport in the area, to allow the athletes to run through Piazza S. Giovanni in Laterano, Piazza del Colosseo, Largo Brancaccio, Via Emanuele Filiberto and Viale Manzoni, before returning to Via Carlo Felice.
