About Jeju City Time Zone
Jeju City uses the Asia/Seoul IANA time zone, the same standard used across all of South Korea. Its standard offset is UTC+9, also known as Korea Standard Time (KST), which means Jeju City is 9 hours ahead of Coordinated Universal Time throughout the year.
South Korea does not currently observe daylight saving time, so Jeju City stays on UTC+9 year-round with no seasonal clock changes in spring or autumn. That consistency is useful for airlines, hotels, logistics firms, and remote teams because meeting times with Jeju City do not shift locally, even though cities in the US, UK, and Australia may move forward or back seasonally.
Jeju City is the capital of Jeju Province, located on Jeju Island off the southern coast of the Korean Peninsula. In regional terms, Jeju City shares the same clock time as Seoul, Busan, and Incheon, and it also matches Tokyo, Japan (UTC+9) year-round; it is 1 hour ahead of Beijing, Shanghai, Hong Kong, and Singapore (UTC+8) and typically 5 hours ahead of Dubai (UTC+4).
Jeju City City Details
Jeju City has a population of 486,306, making it the largest urban center on Jeju Island and the administrative hub of South Korea’s Jeju Special Self-Governing Province. Its size and role make it important for domestic tourism, regional government activity, ferry and air transport, and hospitality operations tied to one of Korea’s busiest leisure destinations.
The city is located at 33.50972° N, 126.52194° E, placing it on the northern side of Jeju Island along key transport and commercial corridors. These coordinates are useful for mapping, travel logistics, weather tracking, and understanding why Jeju City serves as a gateway for flights between the island and major cities such as Seoul, Busan, and international Northeast Asian destinations.
Jeju City uses the South Korean won (KRW) for all local transactions, including hotels, restaurants, transportation, and retail purchases. The country dialing code is +82, so international callers contacting businesses or accommodations in Jeju City should begin with South Korea’s country code before the local number.
Time Differences from Jeju City
Jeju City operates on UTC+9, so its time relationship with other cities depends partly on whether those places are on standard time or daylight saving time. For global scheduling, this matters because Jeju City itself does not change clocks, while cities like New York, London, and Sydney may shift seasonally.
Compared with New York, Jeju City is usually 13 hours ahead during Eastern Daylight Time (UTC-4) and 14 hours ahead during Eastern Standard Time (UTC-5). For example, when it is 9:00 AM in Jeju City, it is typically 8:00 PM the previous day in New York during DST, or 7:00 PM the previous day in winter.
Compared with London, Jeju City is usually 8 hours ahead during British Summer Time (UTC+1) and 9 hours ahead during Greenwich Mean Time (UTC+0). When it is 9:00 AM in Jeju City, it is usually 1:00 AM in London during summer or 12:00 AM during winter, which is why UK-Korea calls often work best in late Korean afternoon.
Compared with Tokyo, Jeju City has no time difference because both use UTC+9 year-round and neither currently changes clocks seasonally. When it is 9:00 AM in Jeju City, it is also 9:00 AM in Tokyo, making Japan one of the easiest markets for same-day meetings and travel coordination.
Compared with Sydney, Jeju City is 1 hour behind when Sydney is on Australian Eastern Standard Time (UTC+10) and 2 hours behind when Sydney is on Australian Eastern Daylight Time (UTC+11). So when it is 9:00 AM in Jeju City, it is usually 10:00 AM in Sydney in standard time or 11:00 AM during Sydney’s daylight saving period.
Compared with Dubai, Jeju City is 5 hours ahead all year because Dubai uses UTC+4 and does not observe daylight saving time. When it is 9:00 AM in Jeju City, it is 4:00 AM in Dubai, so overlapping business hours are usually better in Jeju’s afternoon and Dubai’s morning.
