The paper concerns about not only the involvement of Positivist Church of Brazil members and some allied politicians in proposing Decree 155-B from January 14, 1890, which has established the republican calendar of official holidays, but also their efforts to consolidate it in the political culture of the First Republic. This movement is exemplified through an analysis of the celebration of May 3, 1890, which was decreed a holiday in celebration of the discovery of Brazil.
