KST vs WET: Offsets, DST and Best Call Times

KST runs on Korea Standard Time (KST) at UTC+09:00. WET runs on Western European Time (WET) at UTC+00:00. That puts KST 9 hours behind WET — a difference of -9h at the current offsets.

In practice, when it is 9:00 AM in KST it is 12:00 AM in WET. Midnight in KST is 3:00 PM in WET. Neither zone observes daylight saving time, so the offset between them stays constant all year.

Why people convert KST to WET time

  • Scheduling a call from KST to WET: a 10:00 AM start in KST lands at 1:00 AM in WET, so you can confirm the slot without doing the arithmetic yourself.
  • Handling a -9h gap: KST and WET have no overlap inside a normal 9-to-5 day, so real-time meetings need an early-morning or late-evening slot on one side. 9:00 AM in WET is 12:00 AM in KST.
  • Booking travel or deliveries: tracking WET local time against KST keeps pickup windows and arrival estimates honest across the -9h offset.
  • Always state the zone abbreviation, not just the hour. "3:00 PM KST" is unambiguous; "3 PM" across a -9h gap is not.
  • With a -9h gap there is no shared 9-to-5 window, so alternate the early start: one week KST takes the early slot, the next week WET does.

About KST (Korea Standard Time)

Korea Standard Time (KST) is the time zone used in South Korea. It shares the same UTC offset as Japan Standard Time but is a distinct time zone. South Korea does not observe daylight saving time. Seoul, the capital, is a major global tech and business hub.

About WET (Western European Time)

Western European Time (WET) is used in Portugal, the Canary Islands (Spain), Morocco, and several other locations. It is equivalent to GMT/UTC. During summer, Portugal and the Canary Islands switch to WEST (Western European Summer Time, UTC+01:00).

Best time to call between KST and WET

With a -9h offset there is no overlap inside a normal 9 AM – 5 PM day. WET opens at 9:00 AM WET, which is 12:00 AM in KST, so real-time calls need an early-morning or late-evening slot on one side.

Business hours overlap

KST and WET have no shared working hours because of the -9h gap. Teams need to alternate early starts or rely on asynchronous handovers.

KST is 9 hours behind WET (KST UTC+09:00 → WET UTC+00:00). There is no shared 9-to-5 window, so plan around an early or late slot. Remember to re-check around daylight-saving transitions.
