Converting Indochina Time to Mountain Standard Time
Indochina Time (ICT) and Mountain Standard Time (MST) are separated by a 14 hours time difference. MST is 14 hours behind ICT. ICT is UTC+7, used in Thailand, Vietnam, Cambodia, while MST is UTC-7, used in United States, Canada.
When converting from ICT to MST, the key reference points to remember are: 9:00 AM ICT equals 7:00 PM MST, 12:00 PM noon ICT equals 10:00 PM MST, and 5:00 PM ICT equals 3:00 AM MST. The conversion table above shows every hour of the day mapped between these two time zones.
Scheduling Across ICT and MST
For professionals scheduling meetings between ICT 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 14 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
ICT does not observe Daylight Saving Time, maintaining UTC+7 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.
