How many hours ahead is Korea?
Korea runs on one timezone — KST, UTC+9 — with no daylight saving, so how many hours ahead it is depends on your city and whether your region is on summer time.
The short answer: is Korea ahead or behind you?
Korea is ahead of the Americas, Europe, Africa and most of Asia, and behind Australia and New Zealand.
It is roughly 13–14 hours ahead of New York, 16–17 ahead of Los Angeles, and 8–9 ahead of London.
Korea uses a single nationwide clock — Korea Standard Time (KST), UTC+9 — and does not observe daylight saving.
Because Korea's side never moves, the gap only shifts when your region switches to or from summer time, so the honest answer is usually a small range, not one fixed number.
Korea vs major cities
Korea is ahead by roughly:
| City | Korea is… |
|---|---|
| New York | 13–14h ahead (13 summer / 14 winter) |
| Los Angeles | 16–17h ahead (16 / 17) |
| Chicago | 14–15h ahead |
| London | 8–9h ahead (8 BST / 9 GMT) |
| Paris · Berlin · Madrid · Rome | 7–8h ahead |
| Dubai | 5h ahead (no DST) |
| New Delhi | 3h 30m ahead (no DST) |
| Jakarta | 2h ahead (no DST) |
| Manila · Singapore · Hong Kong | 1h ahead (no DST) |
| Tokyo | Same time (both UTC+9) |
| Sydney | 1–2h behind (Sydney is ahead) |
Ranges show summer / winter where the other city changes its clocks. Cities marked “no DST” keep a fixed offset all year.
Why the difference isn't fixed
Since Korea has no daylight saving, every seasonal shift you see is coming from the other country.
Take New York: for most of the year Korea is 14 hours ahead, but when the US springs forward in March, New York moves an hour closer and the gap drops to 13 hours until the US falls back in early November.
Nothing changed in Seoul — only New York's clock did. That's why a single number can mislead, and why it's safer to think in a range and confirm for the exact date you care about.

Don't do the math in your head.
The live clock on the home page detects your timezone and shows the exact current gap, and the two-way converter turns any Korea time into your local time (and back).
