What’s the Time Difference Between KST and ET?

Let’s break it down:

• KST (Korean Standard Time) is always UTC+9.

• ET (Eastern Time) switches between:

  • EST (Eastern Standard Time) → UTC–5

  • EDT (Eastern Daylight Time) → UTC–4

Depending on the time of year, you’re looking at a 13–14 hour difference.
That means if it’s 9:00 AM in Korea, it could be 7:00 PM or 8:00 PM the previous day on the East Coast. Our tool automatically detects daylight saving time in the U.S., so you don’t have to worry about when clocks change. You just get the correct conversion — every single time.
