Korean Standard Time (KST)

Introduction

Korean Standard Time (KST) is the time zone used in South Korea. It has a time offset of UTC+09:00, making it nine hours ahead of Coordinated Universal Time (UTC). Unlike many other time zones, KST does not observe daylight saving time, providing a consistent time reference throughout the year.

Time Zone History

Korean Standard Time was established to align with the solar time at 135° east longitude. Before the adoption of KST, local mean time was used in various regions. In 1908, the Korean Empire adopted a standard time of GMT+08:30. During the Japanese occupation in 1912, the time zone was changed to GMT+09:00 to align with Japan Standard Time. After World War II, South Korea reverted to GMT+08:30 in 1954, but in 1961, it was changed back to GMT+09:00, where it remains today. South Korea briefly observed daylight saving time during the 1988 Summer Olympics in Seoul to accommodate international broadcasting schedules.

Geographical Coverage

Korean Standard Time is observed throughout the entire country of South Korea. The time zone covers a relatively small geographical area, ensuring uniformity across the nation. KST is equivalent to Japan Standard Time, Pyongyang Time (North Korea), Eastern Indonesia Standard Time, East-Timorese Standard Time, Palau Time, and Yakutsk Time (Russia).

Daylight Saving Time (DST)

South Korea does not currently observe daylight saving time. The concept has been debated over the years, with arguments for and against its implementation. Proponents suggest that DST could save energy and promote outdoor activities, while opponents argue that it would disrupt daily routines and have minimal impact on energy consumption. South Korea last observed daylight saving time during the 1988 Summer Olympics.
