Assumption Day, also known as the Feast of the Assumption, is an important Catholic holiday celebrated in Colombia on the 15th of August each year. The holiday commemorates the biblical event where the Virgin Mary is said to have been assumed, body and soul, into Heaven. This religious event holds deep significance within the Catholic faith, and as Colombia is predominantly Catholic, Assumption Day is widely recognized and observed throughout the country.

On Assumption Day in Colombia, people attend Mass and processions often take place in different cities. These processions are vibrant and colourful with processional floats and statues of the Virgin Mary carried through the streets. It's common to see townspeople marching in these processions, singing hymns and praying. Many Colombians use this day to spend time together with their families, or enjoy public celebrations.

In addition to religious activities, Assumption Day is a public holiday, meaning that schools, government offices, and many businesses are closed. This allows for additional leisure activities such as local festivals, concerts and other cultural events. Traditional food and music are integral parts of these celebrations. Assumption Day provides a significant moment for Colombians to express their deep-seated faith, all while enjoying a sense of unity and cultural celebration.
