About Día de la Constitución (Day of the Constitution)

Puerto Rico’s Día de la Constitución is observed on July 25 each year.

The holiday marks the date in 1952 when Puerto Rico’s Constitution took effect and the Commonwealth government was formally inaugurated under that constitutional framework.

Why Día de la Constitución (Day of the Constitution) matters

The day commemorates Puerto Rico’s constitutional government and the 1952 constitutional milestone.

Because Puerto Rico’s political status is a contested civic subject, this guide describes the legal history without endorsing any political position.

History of Día de la Constitución (Day of the Constitution)

Act No. 1 of August 1, 1952 declared July 25 of each year a legal holiday named Día de la Constitución.

The law explains that the Governor had proclaimed the establishment of the Estado Libre Asociado and put its Constitution into effect on July 25, 1952.

The statutory holiday therefore directly links the recurring date to the Constitution’s 1952 effective date.

Later Puerto Rico holiday legislation continues to list Constitution Day on July 25.
