KST to CT Conversion Guide

What is KST to CT Conversion?

KST to CT conversion helps you translate time between Korea Standard Time and Central Time. KST is UTC+9 and remains constant year-round in South Korea and North Korea with no daylight saving time. CT switches between CST (UTC-6) in winter and CDT (UTC-5) in summer. The time difference varies between 14-15 hours depending on whether Central Time is observing daylight saving time.

Time Zone Information

Korea Standard Time (KST): Used throughout South Korea and North Korea. Always UTC+9 with no seasonal time changes or daylight saving adjustments.

Central Time (CT): Used in central United States, parts of Canada, and Mexico. Switches between CST (UTC-6) in winter and CDT (UTC-5) in summer.

Time Difference: KST is 14 hours ahead of CDT (summer) and 15 hours ahead of CST (winter).

Daylight Saving Time Impact

KST Consistency: Korea Standard Time never changes and remains UTC+9 throughout the year

CT Seasonal Changes: Central Time observes daylight saving from second Sunday in March to first Sunday in November

Variable Difference: Time difference changes from 15 hours (winter) to 14 hours (summer) when CT shifts to daylight saving
