KST
The time zone of the entire Korean Peninsula is the KST (Korea Standard Time) that is 9 hours above the Coordinated Universal Time (UTC+9). South Korea does not observe Daylight Saving Time as many other countries, and therefore, the clock remains the same throughout the year. This renders it extremely easy to not change watches as people plan their work and life.Check the KST Time Now.
