About Tonghae Time Zone
Tonghae, South Korea uses Asia/Seoul, the standard IANA time zone for the entire country. Its local time is UTC+9 all year, and it does not observe daylight saving time, so the clock stays consistent in January, July, and every month in between.
That stability makes scheduling easier for international work tied to South Korea’s east coast. Tonghae sits in Gangwon Province on the Sea of Japan/East Sea side of the Korean Peninsula, and its time matches the rest of South Korea as well as Tokyo, which is useful for regional logistics, shipping coordination, and business calls across Northeast Asia.
Because Tonghae does not shift for daylight saving time, its relationship with cities in the US, UK, and Australia changes seasonally when those places switch clocks. That means a call that works in winter may land an hour differently in summer, especially for teams coordinating between South Korea and New York or London.
