KST vs MST
KST (Korea Standard Time) runs at UTC+9 and MST (Mountain Standard Time) at UTC−7. MST is normally 16 hours behind KST.
KST stays at UTC+9 all year round — it does not observe daylight saving time. MST is the standard time (UTC−7); when daylight saving is in effect it becomes MDT (UTC−6). The live clock on this page always shows the current offset.
