Converting Gulf Standard Time to Central Standard Time
Gulf Standard Time (GST) and Central Standard Time (CST) are separated by a 10 hours time difference. CST is 10 hours behind GST. GST is UTC+4, used in United Arab Emirates, Oman, while CST is UTC-6, used in United States, Canada, Mexico.
When converting from GST to CST, the key reference points to remember are: 9:00 AM GST equals 11:00 PM CST, 12:00 PM noon GST equals 2:00 AM CST, and 5:00 PM GST equals 7:00 AM CST. The conversion table above shows every hour of the day mapped between these two time zones.
Scheduling Across GST and CST
For professionals scheduling meetings between GST 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 10 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
GST does not observe Daylight Saving Time, maintaining UTC+4 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.
