What KST and EST mean here
KST (Korea Standard Time) is UTC+9 all year in South Korea, with no daylight saving time. It is the same clock as Japan (JST).
EST (Eastern Standard Time, UTC−5) is the winter time in New York, Washington, Atlanta, Miami and Toronto. From March 8 to November 1, 2026 those places use EDT (Eastern Daylight Time, UTC−4) instead. Most people who write "EST" mean "Eastern Time, whatever the clocks say today", so this converter follows the clocks in New York and switches between EST and EDT on the right days.
