About time in Sejong

Sejong keeps Korean Standard Time, UTC+9 from UTC all year. The offset never changes, so any difference between you and Sejong moves only when your own clocks do.

Sejong shares the zone Asia/Seoul with Seoul, Busan, Incheon, Daegu, so a time here is also the time there. One canonical page per zone keeps the difference honest: the settlement name changes, the clock does not.

Offsets and daylight saving rules come from the IANA time zone database — see IANA time zone notes for what that data does and does not promise about future dates.
