Ascension Day, locally known as 'Ascensión del Señor', in Colombia is a highly significant Catholic religious tradition that marks the fortieth day after Easter Sunday, when Jesus Christ is said to have ascended to Heaven in the presence of his disciples. Celebrated across the country, this holiday has been central to the faith of millions of Colombians since the arrival of Catholicism with the Spanish in the 16th Century.

This deeply revered holiday stands not only as a day of solemn religious observance but also as an opportunity for Colombians to spend time with family and friends in reflection or celebration. Churches throughout Colombia hold special masses and liturgical activities, creating a unique atmosphere of both joy and respect. It is common for believers to bring flowers to church and participate in community meals as part of the celebrations.

Although Ascension Day is supposed to be celebrated on a Thursday, Colombia, like many other nations, has moved this holiday to the following Sunday to allow for a long weekend. This decision was made to create a time for religious observance while minimizing workday disruptions. The long weekend is very popular among Colombians, not just for its religious significance, but also for the opportunity it provides to relax and enjoy this deeply-rooted cultural occasion.
