How to Find the Time Difference Between CET and KST
Open the CET to KST converter: Visit https://www.xconvert.com/time-converter/cet-vs-kst to load a comparison grid with CET and KST already shown as separate rows on a 24-hour timeline. This page is useful when you need to schedule a supplier call between Germany and South Korea, coordinate a software release between a Berlin product team and a Seoul engineering team, or check whether Korean business hours overlap with Central European office time.
Add relevant comparison cities: Click + Add City and add cities such as Berlin, Paris, and Seoul to compare real business hubs that use these time standards in practice. Berlin and Paris are major European centers for manufacturing, finance, and logistics, while Seoul is a key hub for electronics, gaming, semiconductors, and cross-border trade with companies such as Samsung, LG, and Hyundai operating on Korea Standard Time.
Drag to select a working window: Click Select to enter selection mode, then drag across the CET row to highlight a range such as 9:00 AM to 11:00 AM CET; the purple selection will show the corresponding time in KST as 5:00 PM to 7:00 PM KST on the same day during standard CET. This makes it easy to confirm that a late-afternoon meeting in Seoul can still fit into a European morning, which is especially useful for sales demos, procurement reviews, and remote team handoffs.
Export and share the result: After selecting the time range, use the export options for ICS download, Google Calendar, Gmail, Copy to clipboard, or Share link depending on how you need to send the schedule. For example, you can send an ICS file to a distributed team so Outlook or Apple Calendar converts the meeting automatically, use Google Calendar for a recurring vendor sync, or copy the share link into Slack so colleagues in both Europe and Korea see the same overlap instantly.
CET vs KST Offset Explained
CET (Central European Time) is UTC+1, while KST (Korea Standard Time) is UTC+9, so KST is 8 hours ahead of CET. That means when it is 9:00 AM CET, it is 5:00 PM KST the same day. This 8-hour gap is the standard relationship used in winter by countries and regions observing CET, including much of Central Europe.
The seasonal complication is that many CET locations switch to CEST (Central European Summer Time, UTC+2) during daylight saving time, while KST does not observe DST at all and remains UTC+9 year-round. In 2026, daylight saving time in Central Europe begins on 29 March 2026, when clocks move forward from 2:00 AM to 3:00 AM, and ends on 25 October 2026, when clocks move back from 3:00 AM to 2:00 AM. During that DST period, the difference between Central Europe and Korea becomes 7 hours, not 8.
This means the answer to "CET vs KST" depends on whether you mean strict CET in winter or the local clock time in Central Europe during summer. In winter, 2:00 PM CET = 10:00 PM KST; in summer, 2:00 PM CEST = 9:00 PM KST. For business scheduling, this matters because a meeting that comfortably fits a European morning in January may shift one hour later for Seoul participants after the March DST change.
The practical overlap for office hours is relatively narrow but workable. If a team in Europe works 9:00 AM to 5:00 PM CET, the matching time in Korea is 5:00 PM to 1:00 AM KST, which usually limits live collaboration to Europe’s morning and Korea’s late afternoon or early evening. During European summer time, that overlap improves slightly: 9:00 AM to 5:00 PM CEST becomes 4:00 PM to 12:00 AM KST, giving Korean teams one extra hour before the late-evening window starts.
This offset is especially relevant for industries with Europe–Korea coordination, including automotive supply chains, semiconductor manufacturing, consumer electronics, shipping, and enterprise software support. Seoul is South Korea’s capital with a population of roughly 9.4 million, and the wider Seoul Capital Area exceeds 25 million, making it one of the world’s largest economic regions. On the European side, CET covers major business centers such as Berlin, Paris, Rome, Madrid in winter, Vienna, and Amsterdam, all of which frequently coordinate with Korean partners on procurement, engineering reviews, and international logistics.
Frequently Asked Questions
How many hours is KST ahead of CET?
KST is 8 hours ahead of CET because CET is UTC+1 and KST is UTC+9. For example, when it is 8:00 AM in CET, it is 4:00 PM in KST on the same day. If the European location switches to summer time, the comparison changes to 7 hours because Central Europe then uses UTC+2.
Does Korea change clocks for daylight saving time?
No, South Korea uses KST (UTC+9) all year and does not currently observe daylight saving time. That means the Korean side of the comparison stays fixed, while the European side changes between CET (UTC+1) in winter and CEST (UTC+2) in summer. This is why the time difference is 8 hours in winter and 7 hours during Central European summer time.
Why does the CET to KST time difference change during the year?
The change happens because many countries that use CET in winter move to daylight saving time in spring and use CEST for part of the year. In 2026, Central Europe starts DST on 29 March and ends it on 25 October, while Korea remains on UTC+9 throughout. As a result, the gap narrows from 8 hours to 7 hours during the DST period.
What is the best meeting time between CET and KST?
A common overlap is 9:00 AM to 11:00 AM CET, which corresponds to 5:00 PM to 7:00 PM KST in winter. This works well for product demos, supplier check-ins, and project status meetings because it stays inside normal European office hours and only slightly extends into the Korean evening. During European summer time, the same European slot becomes 4:00 PM to 6:00 PM KST, which is usually even easier for teams in Seoul.
If it is 3 PM CET, what time is it in KST?
If it is 3:00 PM CET, it is 11:00 PM KST the same day because Korea is 8 hours ahead of CET. If the European location is actually on CEST rather than CET, then 3:00 PM CEST = 10:00 PM KST. This distinction is important when booking late-day calls, because a European afternoon can already be near midnight in Korea.
Is CET or KST better for same-day business communication?
Neither is inherently better, but KST’s fixed UTC+9 offset makes Korea easier to predict year-round, while Central Europe requires attention to DST dates. Same-day communication is usually best when Europe schedules in the morning and Korea joins in the late afternoon or early evening. This pattern is widely used for cross-border work in electronics, automotive sourcing, and enterprise customer support.
Can I schedule a call between Germany and South Korea during normal office hours?
Yes, but the overlap is limited and usually favors European mornings and Korean late afternoons. For example, 10:00 AM in Germany on CET is 6:00 PM in South Korea, which is still practical for many teams; in summer, 10:00 AM in Germany on CEST becomes 5:00 PM in Korea. This is why many Europe–Korea meetings are set around 8:00 AM to 11:00 AM in Central Europe for the least disruption on both sides.
