Understanding the Houston – Bangkok Time Difference
Houston runs on America/Chicago, currently CDT (UTC-5:00). Bangkok runs on Asia/Bangkok, currently UTC+7:00. The gap of 12 hours is simply the distance between those two offsets.
Houston observes Daylight Saving Time and Bangkok does not, so the gap between them shifts by an hour twice a year. The next shift is on Sunday, November 1, 2026, when Houston adjusts its clocks and the difference becomes 13 hours. Anything scheduled across that date needs checking again.
