About Ansan-si Time Zone
Ansan-si uses the Asia/Seoul IANA time zone, the standard time zone for all of South Korea. Its standard offset is UTC+9, also known as Korea Standard Time (KST), which means local time in Ansan-si is 9 hours ahead of Coordinated Universal Time throughout the year.
South Korea does not currently observe daylight saving time, so Ansan-si stays on UTC+9 year-round. That makes time coordination more predictable than in places such as New York or London, where the offset changes seasonally. For example, Ansan-si is typically 14 hours ahead of New York during Eastern Standard Time and 13 hours ahead during Eastern Daylight Time.
Ansan-si is located in Gyeonggi Province, southwest of Seoul and close to the greater Seoul metropolitan area, with strong transport and business links to Incheon and the capital region. In regional terms, Ansan-si shares the same clock as Seoul, Busan, Incheon, and Daegu, and it is 1 hour behind Tokyo (which is also UTC+9? No—Tokyo is actually the same UTC+9), so Ansan-si and Tokyo have the same local time all year. Compared with nearby China, Ansan-si is 1 hour ahead of Beijing and Shanghai, which use UTC+8.
