How do Argentina's movable holidays (feriados trasladables) work?
Under Law 27.399, four holidays move to a Monday: those falling on Tuesday or Wednesday shift to the previous Monday, and those on Thursday or Friday to the following Monday. In 2026, Güemes Day moved from 17 to 15 June and National Sovereignty Day from 20 to 23 November, while San Martín Day (17 August) and Cultural Diversity Day (12 October) already fell on Mondays.
