About South Korea

South Korea, officially the Republic of Korea (대한민국, Daehan Minguk), is an East Asian nation occupying the southern half of the Korean Peninsula. The country covers approximately 100,000 square kilometres and is home to over 51 million people, making it one of the world's most densely populated developed countries. It shares its only land border with North Korea along the heavily fortified Demilitarized Zone (DMZ), while the surrounding waters connect it to China to the west across the Yellow Sea, and Japan to the east across the East Sea (Sea of Japan).

The capital is Seoul (서울), one of the world's largest and most dynamic megacities. The Greater Seoul metropolitan area — including the satellite city of Incheon and surrounding Gyeonggi Province — is home to over 25 million people, roughly half of the entire South Korean population. Seoul is a city of fascinating contrasts, where ancient royal palaces like Gyeongbokgung and Changdeokgung sit alongside neon-lit shopping districts, futuristic skyscrapers, and the iconic N Seoul Tower atop Namsan Mountain. The city is divided by the Han River, with the historic centre to the north and the trendy, modern Gangnam district to the south. Myeongdong, Hongdae, Itaewon, and Insadong are world-famous neighbourhoods drawing millions of international visitors annually.

Busan, on the southeastern coast, is South Korea's second-largest city and the country's biggest port — home to the Busan International Film Festival, the famous Haeundae Beach, and the colourful hillside Gamcheon Culture Village. Incheon hosts South Korea's main international gateway, Incheon International Airport, consistently ranked among the world's best airports. Daegu is a major textile and tech city in the southeast, while Daejeon is the country's science and research hub. Gwangju is the cultural heart of the southwest, and Jeju Island — a volcanic island off the southern coast — is South Korea's most popular domestic and international tourist destination, often called the "Hawaii of Korea".

South Korea's geography is dominated by mountains, with around 70% of the country covered by hills and ranges. The most famous peaks include Hallasan on Jeju Island (the country's highest at 1,947m), Seoraksan in the northeast (a UNESCO Biosphere Reserve famous for autumn foliage), and Jirisan in the south. The country has a beautifully indented coastline of around 2,400 kilometres and over 3,000 islands, mostly along the southern and western coasts. The Han River, Nakdong River, and Geum River are the main waterways supporting agriculture and major cities.

Culturally, South Korea has experienced one of the most remarkable transformations of the modern era. After the devastating Korean War (1950–1953), the country was one of the poorest in the world. Today, South Korea is a global cultural and economic powerhouse — home to the Korean Wave (Hallyu) that has spread K-pop, K-dramas, Korean cinema (Parasite became the first non-English film to win the Oscar for Best Picture), Korean food, and Korean beauty (K-beauty) to every corner of the planet. Groups like BTS, BLACKPINK, and Stray Kids have redefined global pop music. Korean food — from kimchi, bibimbap, and Korean BBQ to tteokbokki, samgyeopsal, and Korean fried chicken — is now a global obsession. The country is also famous for its technology giants like Samsung, LG, Hyundai, Kia, and SK Hynix, which dominate global markets in semiconductors, smartphones, displays, electric vehicles, and shipbuilding.

The official language is Korean, written in the elegant and uniquely scientific Hangul alphabet invented by King Sejong the Great in 1443. The vast majority of South Koreans are ethnically Korean, with deep cultural traditions rooted in Confucianism, Buddhism, and Christianity. Major holidays include Seollal (Lunar New Year), Chuseok (the Korean autumn harvest festival), and Buddha's Birthday. The currency is the South Korean Won (KRW / ₩), and South Korea is the world's 12th-largest economy. South Korea is also one of the most digitally advanced nations on Earth — with the world's fastest average internet speeds, near-universal smartphone use, and pioneering 5G rollout.

For travellers and business professionals, South Korea's stable single time zone and lack of daylight saving make scheduling effortless — the country sits at UTC+9 every day of the year, perfectly aligned with Japan and ideally positioned to bridge Asian and Pacific business hours.

Weather and Seasons in South Korea

South Korea experiences four distinct and beautiful seasons, each with its own character. The country sits in a temperate East Asian climate zone, influenced by the Asian monsoon system.

Spring (March – May)

Spring is one of the most beloved seasons in Korea. Cherry blossoms (beot-kkot) bloom across the country in late March and early April, drawing huge crowds to Yeouido in Seoul, Jinhae, and Gyeongju. Temperatures climb gradually from around 8°C to 22°C. Late spring can bring occasional yellow dust storms (hwangsa) blowing in from China and Mongolia.

Summer (June – August)

Summers are hot, humid, and rainy. The monsoon season (jangma) typically arrives in late June and lasts through July, bringing heavy rainfall. Temperatures range from 25°C to 35°C with very high humidity, making coastal cities like Busan and Jeju popular escapes. Late August can also bring typhoons. Despite the heat, summer is festival season — including the famous Boryeong Mud Festival.

Autumn (September – November)

Autumn is widely considered the best season to visit Korea. Skies are clear, humidity drops, and temperatures cool to a pleasant 10–22°C. The country's mountains explode in spectacular foliage colours — Seoraksan, Naejangsan, and Bukhansan are world-famous for autumn views. The major holiday Chuseok (Korean Thanksgiving) falls in September or early October.

Winter (December – February)

Winters are cold and dry, especially in inland and northern regions. Seoul regularly drops to -5°C to -10°C, with snowfall and biting winds. Northern provinces like Gangwon-do are even colder, making them top destinations for skiing — PyeongChang and Yongpyong host major resorts. The southern coast and Jeju Island stay milder at 5–10°C. Winter is also peak season for traditional Korean spa culture and warming dishes like samgyetang (ginseng chicken soup).

Facts About South Korea

• No daylight saving since 1988. The country last used DST during the 1988 Seoul Olympics; it was abandoned shortly after due to public opposition.

• One country, one clock. Despite South Korea's mountainous geography and many islands, the entire country runs on a single time zone.

• Same time as Tokyo. South Korea, Japan, and North Korea all share UTC+9, making travel and communication between Seoul, Tokyo, and Pyongyang seamless on the clock.

• 30 minutes ahead of solar time. Because Korea Standard Time uses the 135° east meridian (which actually passes through Japan), Korean clocks run about 30 minutes ahead of true solar time.

• North Korea briefly went rogue. In 2015, North Korea created its own "Pyongyang Time" at UTC+8:30. They reverted to UTC+9 in 2018 to align again with the South.

• The Korean age system used to add a year on January 1. Until 2023, Koreans were considered 1 year old at birth and added a year every New Year's Day — but this was abolished in favour of the international system.

Frequently asked questions

What time zone is South Korea in?

South Korea is in Korea Standard Time (KST) at UTC+9 year-round. This is the same time zone used by Japan and North Korea, making it tightly synchronised across East Asia. South Korea uses this single time zone across the entire country, with no regional variation between Seoul, Busan, Jeju Island, or any other location.

Is South Korea on the same time as Japan?

Yes. South Korea and Japan both operate on UTC+9 — Korea Standard Time (KST) and Japan Standard Time (JST) are identical offsets. This means scheduling between Seoul, Tokyo, Osaka, or any other Korean and Japanese cities requires no time calculation at all. North Korea also uses UTC+9, putting all three Korean Peninsula and Japanese clocks in sync.

Does South Korea observe daylight saving time?

No, South Korea does not observe daylight saving time. The country experimented with DST briefly during the American military administration after World War II, and again in 1987 and 1988 specifically for the Seoul Olympics, but it was abandoned each time due to public dissatisfaction. Today, KST stays at UTC+9 every single day of the year, with no clock changes in spring or autumn.

What does KST stand for?

KST stands for Korea Standard Time, the official time zone of South Korea (and also used by North Korea) at UTC+9. The abbreviation is widely recognised in international business, especially in technology, entertainment, and gaming industries where Korean companies and esports tournaments operate. South Korea has used KST consistently — without daylight saving — since 1988.

How many time zones does South Korea have?

South Korea has just one time zone covering the entire country. From the northern border with North Korea down to the southern resort island of Jeju, every city, town, and village uses the same official Korea Standard Time. This single time zone makes practical sense given South Korea's relatively compact size — you can drive across the country in about 5 hours.

What is the best time to call South Korea from Australia?

The best window for calling South Korea from Sydney is between 10:00 AM and 6:00 PM AEST, which corresponds to 9:00 AM to 5:00 PM Seoul time — almost perfect business hours overlap on both sides. Because South Korea is only 1 to 2 hours behind eastern Australia, both parties can comfortably stay within standard business hours throughout the day.

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

South Korea is 9 hours ahead of the UK during British winter (GMT) and 8 hours ahead during British Summer Time (BST). When it's 9:00 AM in London during winter, it's already 6:00 PM in Seoul. The difference shifts by one hour twice a year because the UK observes daylight saving while South Korea does not.

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

South Korea is 13 to 14 hours ahead of New York (Eastern Time) and 16 to 17 hours ahead of Los Angeles (Pacific Time), depending on US daylight saving. This makes South Korea and the US East Coast roughly half a day apart — when it's noon in New York, it's around 1:00 AM the next day in Seoul. US-Korea business often relies on early morning US calls catching late afternoon Korean time.

What is the best time to call South Korea from the United States?

From the US East Coast, calling between 8:00 PM and 10:00 PM ET works well, landing at 9:00 AM to 11:00 AM the next day in Seoul. From the West Coast, calling between 5:00 PM and 7:00 PM PT lands at the same morning window in Korea. Korean tech and entertainment companies operate around the clock to serve global markets, so flexible scheduling windows are common.

What time does South Korea's stock market open and close?

The Korea Exchange (KRX), which operates the KOSPI and KOSDAQ markets, opens at 9:00 AM KST and closes at 3:30 PM KST, Monday through Friday. There's no midday lunch break — trading is continuous. The exchange is headquartered in Busan with primary trading operations in Seoul, and follows Korean public holidays including Seollal (Lunar New Year) and Chuseok (autumn harvest festival).

Is Seoul time the same as Busan time?

Yes, Seoul and Busan use exactly the same time — both operate on Korea Standard Time at UTC+9. In fact, every city across South Korea, from Incheon and Daegu to Jeju Island and the DMZ, runs on identical official time. There is zero time difference between any two locations in South Korea, regardless of how far apart they are.

What is South Korea's international calling code?

South Korea's international dialling code is +82, which must be dialled before any Korean phone number when calling from overseas. Korean mobile numbers typically begin with 10 (after dropping the leading 0), so the international format is +82 10 XXXX XXXX. For landlines, you dial +82 followed by the area code (without the leading 0) — Seoul's area code is 2, Busan's is 51, and Incheon's is 32.
