Constitution Day in Uruguay

The oath that marked a new state

The Constitution of the Estado Oriental del Uruguay was sworn on July 18, 1830, at Montevideo’s Cabildo before the provisional governor and civil, religious, and military authorities. Uruguay’s Ministry of Education and Culture describes the event as a founding milestone for the emerging state.[4]

The 1830 constitution set out a representative republican form of government, separation of powers, and the organization of the territory. The date is therefore tied to the creation of Uruguay’s constitutional order, rather than to the adoption of its current constitution.[5][6]

A fixed date and a paid holiday

Uruguay’s Labor Ministry lists July 18 among the five paid holidays established by law. Under the cited labor law, workers receive their usual remuneration for the day; if they work, they receive double pay. This pay rule applies to workers and does not by itself establish that every workplace must close.[1][2]

July 18 is specifically exempt from the usual weekday-shifting rules for certain holidays. It is observed on the calendar date even when that date falls on a Saturday or Sunday, so there is no substitute Monday under the cited law.[1][3]

Commemorations

Official commemorations have included a ceremony at Plaza Constitución in Montevideo, followed by military and police units, gaucho horsemen, a floral tribute, and a moment of silence at the Obelisk to the Constituents of 1830. These are documented elements of an official anniversary program; arrangements may vary from year to year.[5]

The historical oath itself was a public civic ceremony in Montevideo. The Ministry of Education and Culture records that it took place at the Cabildo before state authorities, and Uruguay’s legislative library identifies July 18, 1830, as the date the first constitution came into force.[4][6]

What to expect for daily services

Check opening hours with government offices and banks before you go. Opening hours and service timetables for banks, shops, attractions and public transport can depend on the organization or operator; check locally before making plans. Some employees may work on the holiday for double pay.[1][2]
