Understanding the San Francisco – Bangkok Time Difference
San Francisco runs on America/Los_Angeles, currently PDT (UTC-7:00). Bangkok runs on Asia/Bangkok, currently UTC+7:00. The gap of 14 hours is simply the distance between those two offsets.
San Francisco 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 San Francisco adjusts its clocks and the difference becomes 15 hours. Anything scheduled across that date needs checking again.
