🇰🇷 Seul

Seoul, the capital of South Korea, has a population of about 10.3 million in the country's northwest near 38 degrees north latitude. It keeps Korea Standard Time at UTC+9 and does not observe daylight saving, so its clocks stay nine hours ahead of Coordinated Universal Time throughout the year. Lying in the Northern Hemisphere at a mid-latitude, the city has four distinct seasons with clear differences in daylight between summer and winter, though the clock offset remains fixed. Korea shares the UTC+9 band with Japan, and Seoul's steady offset makes its time relationship to other regions consistent from month to month.
