About EST and KST
EST (Eastern Time (US)) covers USA and Canada and is anchored to the IANA zone America/New_York. It observes daylight saving time, so the offset shifts by one hour twice a year.
KST (Korea Standard Time) covers South Korea via Asia/Seoul. It does not observe daylight saving time.
Because at least one of these zones uses DST, the time difference between EST and KST is not constant — it shifts by an hour during the spring and autumn DST transitions. The hour grid below recomputes the difference for any specific date you click, using the IANA rules baked into your browser.
