한국 표준시(KST) is the time zone used in South Korea. It is 9 hours ahead of Coordinated Universal Time (UTC+9) and does not observe daylight saving time. KST is used throughout the country for all official and daily activities. KST is important for scheduling events, transportation, and communication both domestically and internationally. It helps synchronize activities with other regions, especially those in neighboring countries like 일본 and 중국, which also have their own standard time zones.
