Convert a specific time from KST to CST
Pick any time and date to convert it both ways. The conversion runs in your browser against the real zone rules, so a date inside a daylight saving period gets that period's offset rather than today's.
What is the time difference between KST and CST?
Central Time is 14 hours behind Korea Standard Time. To go from KST to CST you subtract 14 hours. That gap is not fixed. Across 2026 the distance between these two zones takes 2 different values, from 14 hours to 15 hours, because Central moves its clocks and Korea does not. This page recomputes it rather than assuming.

What are the best hours to schedule a call between KST and CST?
No hour of the standard 9:00 am to 5:00 pm working day falls inside working hours on both sides. Korea and Central are 14 hours apart, which is too far for an overlap, so somebody has to take a call outside their own working day. The least painful options are below, ranked by how close both sides sit to the middle of the afternoon.
| KST | CST | Working hours | Note |
|---|---|---|---|
| 7:00 am | 5:00 pm the previous day | neither side | early morning in Korea, evening in Central |
| 8:00 am | 6:00 pm the previous day | neither side | mid morning in Korea, evening in Central |
| 9:00 am | 7:00 pm the previous day | KST only | mid morning in Korea, evening in Central |
Does daylight saving change KST to CST?
Korea Standard Time does not move its clocks at all, so its UTC+9 offset holds every day of the year.
Central Time is currently on CDT and changes next on Sunday, November 1, 2026, when the clock falls back from 1:59 am to 1:00 am and the offset moves from UTC-5 to UTC-6.
Because the two sides do not move together, the answer to this conversion changes during the year. For part of the year the gap is 14 hours and for the rest it is 15 hours. The table above is built for today, not for an average day.
Is KST ahead of or behind CST?
KST is ahead of CST by 14 hours: when it is 12:00 pm in Korea, it is 10:00 pm the previous day in Central. One wrinkle worth knowing: CST and CDT are two names for the same zone, not two zones. Central Time reads CST in winter and CDT in summer. When somebody types "kst to cst" they nearly always mean the zone rather than the literal winter offset, so this page resolves KST to Asia/Seoul and CST to America/Chicago and applies whichever offset is genuinely in force on the day.
Korea Standard Time covers Seoul and South Korea. Central Time covers Chicago, Dallas, Houston and Winnipeg. The identifiers behind them are Asia/Seoul and America/Chicago, which is what any calendar or scheduling system should be storing rather than a fixed number of hours.
