Why Colombia Has Two Key Political Dates

Colombia has two major political dates just 18 days apart, but they mark different changes of government. July 20 begins a new four-year term for Congress, while Aug. 7 begins a new four-year presidential term. The two institutions belong to separate branches of government and follow different calendars.

Both dates also have roots in Colombia’s independence from Spain, which can make them confusing for foreign readers. In 2026, the distinction is especially relevant: the new Congress began its 2026-2030 legislative period on July 20, while the presidential transition will take place on August 7, when Gustavo Petro leaves office, and president-elect Abelardo de la Espriella takes office.

The historical connection is straightforward: July 20 recalls the beginning of Colombia’s independence movement, while August 7 commemorates the military victory that helped secure it. Their political functions, however, are different.

What July 20 means for Colombia’s Congress

July 20 is Colombia’s Independence Day. It commemorates the events of 1810, when an uprising in Santa Fe, the capital of the Spanish Viceroyalty of New Granada, began the process that eventually led to independence.

The episode is known as the Grito de Independencia, or Cry of Independence. A dispute involving Spanish merchant Jose Gonzalez Llorente and a request to borrow a flower vase became a trigger for public unrest. Local political leaders used the confrontation to challenge Spanish authority, helping set the independence movement in motion.

July 20 also serves as the fixed opening date for Colombia’s Congress. The Senate and House of Representatives begin their four-year legislative periods on that day.

Law 5 of 1992, which establishes the internal rules of Congress, sets July 20 as the date for the installation of a newly elected legislature. Senators and representatives take office, the two chambers organize themselves and each chamber elects its leadership.

The date therefore links a national independence anniversary with the beginning of a new legislative period.

What August 7 means for Colombia’s presidency

August 7 commemorates the Battle of Boyaca, fought in 1819. The victory of independence forces over the Spanish royalist army was decisive in the campaign to liberate New Granada and opened the way toward the creation of an independent republic.

The date is also associated with the beginning of Colombia’s presidential terms. Every four years, the president-elect takes office on August 7, while the outgoing president’s term ends the previous day.

The Constitution establishes the inauguration ceremony. Article 192 requires the president to take the oath of office before Congress and swear to uphold the Constitution and laws of Colombia.

The incoming president therefore takes office in a ceremony involving the country’s legislature, rather than through a separate executive procedure.

Why are the dates different?

The two dates exist because Colombia’s legislative and executive branches have separate terms and separate constitutional procedures.

Congress begins its four-year period on July 20 under the rules governing its installation. The president begins a four-year term on Aug. 7 and takes the oath before Congress.

The 18-day gap gives the newly elected legislature time to install its members and organize the two chambers before Congress meets in plenary session for the presidential inauguration. The Senate and House elect their respective leaders during this period.

The sequence connects the two institutions without making their terms simultaneous. The legislature begins first; the executive changes later.

How the distinction applies to Colombia’s 2026 transition

The 2026 political transition follows this established calendar. Congress began its 2026-2030 period on July 20. The new senators and representatives were installed at the Capitol, and both chambers elected their leadership. President Gustavo Petro attended the congressional installation and delivered his final July 20 address as president.

Petro’s presidential term ends on August 6. On Aug. 7, Abelardo de la Espriella is scheduled to take office as Colombia’s next president.

The 2026 inauguration also includes an unusual logistical change. Instead of holding the ceremony in Bogota, Congress is preparing to meet in Cali for the presidential handover. The Senate initially approved a proposal to move its session to Cauca, but the president-elect later proposed Cali, and the Chamber of Representatives approved the change. The ceremony is scheduled for the Arena USC at the University of Santiago de Cali.

The location changes, but the institutional roles remain the same: Congress began its new term on July 20, and the president-elect will take office on Aug. 7 before the legislature.
