KST to MST Converter

Converting Korea Standard Time to Mountain Standard Time

Korea Standard Time (KST) and Mountain Standard Time (MST) are separated by a 16 hours time difference. MST is 16 hours behind KST. KST is UTC+9, used in South Korea, while MST is UTC-7, used in United States, Canada.

When converting from KST to MST, the key reference points to remember are: 9:00 AM KST equals 5:00 PM MST, 12:00 PM noon KST equals 8:00 PM MST, and 5:00 PM KST equals 1:00 AM MST. The conversion table above shows every hour of the day mapped between these two time zones.

Scheduling Across KST and MST

For professionals scheduling meetings between KST and MST, finding overlapping business hours is essential. Standard business hours are typically 9:00 AM to 5:00 PM in each time zone. Given the 16 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. MST observes DST, switching to MDT (UTC-6). 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.
