How the gap works

The gap is not constant. Because Chicago changes its clocks for daylight saving time and Bangkok does not, the difference becomes 13 hours for part of the year. The live section above shows the exact gap right now and when it next changes.

  • Chicago (United States) is in the America/Chicago time zone: UTC-6 (CST) or UTC-5 (CDT).
  • Bangkok (Thailand) is in the Asia/Bangkok time zone: UTC+7.

Best time to call or meet
