Argentina operates on Argentina Time (ART) year-round, which is 3 hours behind Coordinated Universal Time (UTC-3). Argentina does not observe daylight saving time, so the time remains consistent throughout the year.
All of Argentina follows the same timezone. Major cities including Buenos Aires, Córdoba, Rosario, Mendoza, and Mar del Plata all observe ART. Argentina shares the same timezone as Brazil (Brasília time), Uruguay, and parts of Chile during certain months.
Argentina is the eighth-largest country in the world and the second-largest in South America. Buenos Aires is known as the "Paris of South America" due to its European-style architecture. Argentina is the birthplace of tango and is home to Aconcagua, the highest peak in the Western Hemisphere at 6,961 meters.
