South America Time Zones

About South America

South America is the world's fourth-largest continent, covering approximately 17.8 million square kilometres — that's about 12% of the Earth's land area. The continent stretches from the Caribbean Sea in the north to Cape Horn in the south, and from the Pacific Ocean in the west to the Atlantic Ocean in the east. South America is home to around 435 million people across 12 sovereign countries, plus the French overseas territory of French Guiana.

The continent is dominated by Brazil, which alone covers roughly half of South America's land area and is home to over 210 million people. Other major countries include Argentina, Colombia, Peru, Venezuela, Chile, Ecuador, Bolivia, and Paraguay. South America's history is shaped by ancient pre-Columbian civilisations — including the Incas, Moche, Tiwanaku, and dozens of other cultures — followed by Spanish and Portuguese colonisation beginning in the 16th century. Today, Spanish is the dominant language across most of the continent, with Portuguese spoken in Brazil and English, Dutch, and French spoken in the small Guianas region.

South America's geography is breathtakingly diverse — from the Andes (the world's longest mountain range, stretching 7,000 kilometres along the western coast and including peaks over 6,900 metres), to the vast Amazon Rainforest (covering nearly 40% of the continent), the Pampas grasslands of Argentina and Uruguay, the dry Atacama Desert in northern Chile (the driest non-polar desert on Earth), the spectacular Patagonia region of southern Chile and Argentina, the Iguaçu Falls on the Brazil-Argentina border, Lake Titicaca (the highest navigable lake in the world), and the unique Galápagos Islands.

For travellers and business professionals, South America's time zones are relatively simple compared to other continents — the bulk of the continent uses just two main offsets (UTC-3 and UTC-5), and most countries no longer observe daylight saving time. The main exceptions are Chile and Paraguay, which still shift their clocks twice a year, plus a few small territorial variations.

South America's Time Zones

South America officially spans 5 main time zones, ranging from UTC-2 to UTC-6. From east to west:

🕐 Fernando de Noronha Time — UTC-2

The easternmost South American time zone, used only by Brazil's Atlantic islands of Fernando de Noronha and the Trindade and Martim Vaz archipelago. Brazil abolished DST in 2019, so these islands stay at UTC-2 year-round.

🕑 Brazil / Argentina / Uruguay Time — UTC-3

The most populous South American time zone, covering:

• Brazil (most of the country, including Brasília, Rio de Janeiro, São Paulo, Salvador)

• Argentina (entire country)

• Uruguay (entire country)

• Suriname, French Guiana, Falkland Islands

• Chile (Magallanes Region) — stays at UTC-3 year-round

🕒 Venezuela / Bolivia / Paraguay / Chile Time — UTC-4 / UTC-3 (DST in Chile and Paraguay)

Used across the central western region:

• Bolivia (UTC-4 year-round, no DST)

• Venezuela (UTC-4 year-round)

• Guyana (UTC-4 year-round)

• Paraguay (UTC-4 / UTC-3 with DST)

• Chile (UTC-4 / UTC-3 with DST — most of the country including Santiago)

• Brazil (Acre and parts of Amazonas — UTC-5 actually, see below)

🕓 Colombia / Ecuador / Peru Time — UTC-5

The Pacific-side South American time zone:

• Colombia (entire country)

• Ecuador (mainland)

• Peru (entire country)

• Brazil (Acre state and western Amazonas — UTC-5 year-round)

🕔 Galápagos Time — UTC-6

Used by Ecuador's Galápagos Islands in the Pacific Ocean — one hour behind mainland Ecuador.

Daylight Saving Time in South America

Most of South America no longer observes daylight saving time — making the continent significantly easier to coordinate with than it was a decade ago. Here's the current status:

South American countries that DO observe DST

• Chile — Switches from CLT (UTC-4) to CLST (UTC-3) typically from early September to early April. The far southern Magallanes Region stays at UTC-3 year-round.

• Paraguay — Switches from PYT (UTC-4) to PYST (UTC-3) typically from October to March.

South American countries that do NOT observe DST

• Argentina — Hasn't observed DST since 2009; stays at UTC-3 year-round.

• Bolivia — Has never used DST in its modern history.

• Brazil — Abolished DST in 2019 after decades of use. The entire country now stays on fixed UTC offsets.

• Colombia — Tried DST briefly in the 1990s but has not used it since.

• Ecuador — Does not observe DST.

• Peru — Does not observe DST.

• Uruguay — Last observed DST in 2014; now stays at UTC-3 year-round.

• Venezuela — Does not observe DST.

• Guyana, Suriname, French Guiana — None observe DST.

This widespread abolition of daylight saving across the continent makes intra-South American business scheduling refreshingly stable year-round, with only Chile and Paraguay creating seasonal complications.

What South America is Famous For

• Brazil abolished DST in 2019. After decades of using daylight saving, Brazil dropped the system entirely — so the entire country now stays on fixed UTC offsets year-round.

• Argentina is unusually far east on its clock. Geographically, much of Argentina sits at the same longitude as Chile, but Argentina uses UTC-3 (matching Brazil) while Chile uses UTC-4 — meaning the sun sets noticeably "later" by official time in Buenos Aires than in Santiago.

• The Galápagos Islands are 1 hour behind mainland Ecuador. Despite being part of the same country, the Galápagos use UTC-6 while Quito uses UTC-5.

• Brazil spans 4 time zones. Most of Brazil is on UTC-3, but the western state of Acre is on UTC-5, parts of central Brazil are on UTC-4, and the Atlantic islands of Fernando de Noronha are on UTC-2.

• Chile's southern Magallanes Region stays at UTC-3 year-round. While the rest of Chile shifts between UTC-4 and UTC-3, this far-southern region simply stays on UTC-3 permanently.

• South America is the only inhabited continent where most countries don't observe DST. Of the 12 sovereign nations, only Chile and Paraguay still use daylight saving time.

Facts About South America

Frequently asked questions

How many time zones are in South America?

South America has 5 main time zones from UTC-2 (Brazil's Atlantic islands) to UTC-6 (the Galápagos Islands). The two most populous are UTC-3 (Brazil, Argentina, Uruguay) and UTC-5 (Colombia, Peru, Ecuador). Most of the continent uses just two or three offsets, making it one of the simpler continents to coordinate with internationally.

Is São Paulo on the same time as New York?

Not quite. São Paulo is typically 1 to 2 hours ahead of New York, depending on US daylight saving. During US winter (November to March), São Paulo is 2 hours ahead of New York. During US summer (March to November), the gap shrinks to just 1 hour. Brazil hasn't observed DST since 2019, so the gap shifts only because of US DST changes.

Does South America observe daylight saving time?

Most of South America does NOT observe daylight saving time. Of the 12 sovereign countries, only Chile and Paraguay still use DST. Brazil abolished DST in 2019, Argentina hasn't used it since 2009, and Uruguay dropped it in 2014. Bolivia, Colombia, Ecuador, Peru, Venezuela, Guyana, Suriname, and French Guiana have never used it (or haven't in many years). This makes most South American time zones refreshingly stable year-round.

Why did Brazil abolish daylight saving time?

Brazil abolished DST in 2019 after president Jair Bolsonaro's government determined that the seasonal clock change no longer provided meaningful energy savings due to changes in modern electricity consumption patterns. Studies showed that air conditioning use in summer evenings actually increased energy demand during DST, partially offsetting any morning lighting savings. The clock change also disrupted business and health, so the government discontinued the practice.

What time zone is most of South America in?

The most populous South American time zone is UTC-3, used by Brazil (most of the country), Argentina, Uruguay, Suriname, and French Guiana — covering over 280 million people. The second most populous is UTC-5, used by Colombia, Peru, and mainland Ecuador.

What is the easternmost time zone in South America?

The easternmost South American time zone is UTC-2, used by Brazil's Atlantic island groups including Fernando de Noronha and Trindade and Martim Vaz. These remote volcanic islands sit far east of mainland Brazil in the Atlantic Ocean and have their own time zone for geographic reasons.

What is the time difference between Brazil and Argentina?

There is no time difference — Brazil (most regions) and Argentina are both on UTC-3 year-round. When it's 12:00 PM in São Paulo, it's also 12:00 PM in Buenos Aires. This makes the two largest South American economies extremely easy to coordinate with each other on time.

What is the time difference between South America and the UK?

It depends heavily on which country and the time of year. Brazil and Argentina are 3-4 hours behind the UK (3 hours in UK summer, 4 hours in UK winter). Colombia, Peru, and Ecuador are 5-6 hours behind. Chile and Paraguay shift seasonally — usually 4-5 hours behind during their respective summer/winter cycles. The UK observes DST while most of South America does not, so the gap shifts twice a year.

What is the time difference between South America and the United States?

South American countries are typically 0 to 4 hours ahead of US time zones. Buenos Aires and São Paulo are 1-2 hours ahead of New York. Lima, Bogotá, and Quito are on the same time as New York during US winter (both UTC-5) but 1 hour behind during US summer. Santiago is 1-2 hours ahead of New York depending on Chilean DST.

Does Chile observe daylight saving time?

Yes — Chile is one of only two South American countries that still observes DST (alongside Paraguay). Chile shifts from CLT (UTC-4) to CLST (UTC-3) typically from early September to early April. However, the far-southern Magallanes Region (which includes Punta Arenas) stays at UTC-3 year-round and does not change clocks. The Easter Island time zone (UTC-6) also follows Chilean DST.

Are the Galápagos Islands on the same time as mainland Ecuador?

No. The Galápagos Islands are 1 hour behind mainland Ecuador. Quito uses UTC-5 (Ecuador Time), while the Galápagos use UTC-6 (Galápagos Time) due to their position about 1,000 km west of mainland Ecuador in the Pacific Ocean. Visitors flying from Quito to the Galápagos need to set their watches back 1 hour upon arrival.

What is the westernmost time zone in South America?

The westernmost South American time zone is UTC-6, used by Ecuador's Galápagos Islands. These remote Pacific islands sit about 1,000 km west of mainland Ecuador and require a separate time zone to reflect their actual longitude.
