Korea World Flight & Time Zone
ICN to 50 airports flight duration and time zone with jet-lag tips.
About this tool
Korea World Flight & Time Zone calculates flight duration (Great Circle), time difference, and arrival local time from Incheon (ICN) to 50 major airports — Tokyo, New York, London, Bangkok, etc. — in one page. DST is auto-applied via the IANA timezone database, and adding a layover (e.g., ICN → DOH → LHR) computes total trip time. Includes a jet-lag adaptation guide (light exposure / meals / sleep) keyed to the destination local time, plus six popular-route presets, favorites, and share URLs.
Use cases
Scenario 1
NYC arrival local time
Departing ICN 10:00 KST for a 14-hour flight to JFK lands you at "11:00 same day" NYC — schedule meetings around that.
Scenario 2
Tokyo same-day round trip
A 2.5-hour ICN → NRT flight with no time-zone gap makes a same-day Tokyo trip realistic — simulate timing.
Scenario 3
London via Doha layover
ICN → DOH → LHR with a 4-hour Doha layover totals ~16 hours; the tool shows LHR arrival local time.
Scenario 4
Jet-lag adaptation guide
After arriving NYC, get a local-time plan ("30 min afternoon sun, 18:00 dinner, 22:00 sleep") to recover faster.
Scenario 5
Share trip schedule with family
Send the URL with ICN → LAX departure / arrival to family or your driver so everyone reads the same schedule.

Frequently asked
- Q. How close is the estimate to a real flight?
- A. Within ±30 min typically. Real flights vary with winds, routing, and clearance — check the carrier’s schedule for an exact figure.
- Q. How is DST handled?
- A. Auto-applied via the IANA timezone database. U.S. / European DST shifts are picked up based on departure date.
- Q. How do I add a layover?
- A. Toggle the layover option, pick the connecting airport, and enter wait time in hours (e.g., 1.5 h) — the tool sums leg 1 + wait + leg 2.
- Q. Jet-lag guide — based on what?
- A. It uses generally accepted recommendations (light timing / meals / sleep). For health conditions or medications, consult a doctor.
- Q. Is this an airline tool?
- A. No — it is an unofficial estimator. For real flight info and ticketing, use the carrier’s site.
