Converting Korea Standard Time to Central Standard Time
Korea Standard Time (KST) and Central Standard Time (CST) are separated by a 15 hours time difference. CST is 15 hours behind KST. KST is UTC+9, used in South Korea, while CST is UTC-6, used in United States, Canada, Mexico.
When converting from KST to CST, the key reference points to remember are: 9:00 AM KST equals 6:00 PM CST, 12:00 PM noon KST equals 9:00 PM CST, and 5:00 PM KST equals 2:00 AM CST. The conversion table above shows every hour of the day mapped between these two time zones.
Scheduling Across KST and CST
For professionals scheduling meetings between KST and CST, finding overlapping business hours is essential. Standard business hours are typically 9:00 AM to 5:00 PM in each time zone. Given the 15 hours difference, the window of overlap may be limited, making early morning or late evening calls necessary for one party. Use the highlighted working hours in the conversion table above to quickly identify suitable meeting times.
Daylight Saving Time Considerations
KST does not observe Daylight Saving Time, maintaining UTC+9 year-round. CST observes DST, switching to CDT (UTC-5). During DST transitions, the time difference between these zones may temporarily change by 1 hour. Always verify the current offset during spring and fall transition periods.
