Indochina Time (ICT) and Central Standard Time (CST) are separated by a 13 hours time difference. CST is 13 hours behind ICT. ICT is UTC+7, used in Thailand, Vietnam, Cambodia, while CST is UTC-6, used in United States, Canada, Mexico.
When converting from ICT to CST, the key reference points to remember are: 9:00 AM ICT equals 8:00 PM CST, 12:00 PM noon ICT equals 11:00 PM CST, and 5:00 PM ICT equals 4:00 AM CST. The conversion table above shows every hour of the day mapped between these two time zones.
Scheduling Across ICT and CST
For professionals scheduling meetings between ICT and CST, finding overlapping business hours is essential. Standard business hours are typically 9:00 AM to 5:00 PM in each time zone. Given the 13 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. CST observes DST, switching to CDT (UTC-5). 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.
