Daylight saving time note

London and Seoul do not change their clocks on the same date. Between October 25, 2026 and March 28, 2027 the difference is 9 hours behind Seoul — because London changes its clocks for daylight saving time while Seoul keeps the same time all year.

For the rest of the year the difference holds steady at 8 hours. Every time on this page is computed from the IANA database at the moment you load it, so the tables above already account for whichever side has switched.
