Current Time in Buenos Aires

Quick Time Zone Facts

Time Zone: Argentina Time (ART) — Standard Offset: UTC-3 (ART) — DST: Not observed

Country: Argentina

This city does not observe Daylight Saving Time. The UTC offset remains constant year-round, which simplifies international scheduling.

No Daylight Saving Time

Argentina does not observe DST, keeping Buenos Aires on ART (UTC-3) year-round. Argentina experimented with DST as recently as 2008-2009 but abandoned it. The constant UTC-3 offset simplifies scheduling with Brazil (much of which shares the same offset as BRT/UTC-3) and creates a manageable gap with Europe — Buenos Aires is just 3 hours behind London in winter and 4 behind during BST.

South American Business

Buenos Aires shares its UTC-3 offset with São Paulo, making Argentina-Brazil coordination seamless — important given they're each other's largest trading partners within Mercosur. The city's financial district operates from roughly 10 AM to 5 PM ART. Argentina's agricultural commodities sector (one of the world's largest exporters of soybeans, corn, and wheat) coordinates with Chicago commodities markets that open at 8:30 AM CT (10:30 AM ART).

European Connection

Buenos Aires has strong cultural and business ties to Europe, particularly Spain and Italy. The 4-5 hour time difference with Western Europe (depending on DST) is manageable — a 2 PM CET call catches Buenos Aires at 10 AM ART. This relatively small gap for a South American city reflects Argentina's historical European immigration patterns and ongoing trade relationships.

US Scheduling

Buenos Aires is 2 hours ahead of New York during EDT and 2 hours ahead during EST. Wait — ART is UTC-3 and EST is UTC-5, so BA is 2 hours ahead of New York in winter. During EDT (UTC-4), BA is just 1 hour ahead. This makes Buenos Aires one of the most schedule-friendly South American cities for US East Coast business. A 10 AM ET meeting is 11 AM or 12 PM in Buenos Aires, depending on season.
