CST to KST Converter

Converting Central Standard Time to Korea Standard Time

Central Standard Time (CST) and Korea Standard Time (KST) are separated by a 15 hours time difference. KST is 15 hours ahead of CST. CST is UTC-6, used in United States, Canada, Mexico, while KST is UTC+9, used in South Korea.

When converting from CST to KST, the key reference points to remember are: 9:00 AM CST equals 12:00 AM KST, 12:00 PM noon CST equals 3:00 AM KST, and 5:00 PM CST equals 8:00 AM KST. The conversion table above shows every hour of the day mapped between these two time zones.

Scheduling Across CST and KST

For professionals scheduling meetings between CST and KST, 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

CST observes Daylight Saving Time, switching to CDT (UTC-5) during summer months. KST does not observe DST, staying at UTC+9 year-round. 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.
