UTC (Coordinated Universal Time) is 9 hours behind KST (Korea Standard Time). This means when it's 12:00 PM in Seoul (KST), it's 3:00 AM in UTC (UTC).
The best time to call from KST to UTC is during overlapping business hours. For KST callers, schedule between 12:00 PM - 5:00 PM KST to ensure both parties are within standard business hours.
The time difference may change during daylight saving transitions if one region observes DST while the other doesn't. Korea Standard Time (UTC+9) and Coordinated Universal Time (UTC+0) may have different DST schedules.
KST includes cities like Seoul. UTC includes cities like UTC. Both time zones cover important business and cultural centers.
In 2025, DST in North America starts on March 9 at 2:00 AM and ends on November 2 at 2:00 AM. Other regions may have different DST schedules or not observe DST at all.
