When the difference changes

Indochina Time and Central Time do not change their clocks on the same dates, so the gap between them is not the same all year. Most converters show only today’s figure. These are the periods ahead:

  1. Now – March 14, 2027Central Time is 13 hours behind
  2. March 14, 2027 – November 7, 2027Central Time is 12 hours behind
  3. November 7, 2027 – onwardsCentral Time is 13 hours behind

Periods shorter than a day are not listed. Each zone changes at its own local time, so on a date when both move there are a few hours when the gap is briefly something else.

Daylight saving

Indochina Time

No clock changes

Indochina Time stays on ICT all year, so its offset from UTC never moves.

Central Time

Sunday, March 14, 2027

Clocks go forward one hour — 2:00 am becomes 3:00 am local time, and the zone is on CDT after that.

Scheduling between the two

There is no overlap between a nine-to-six working day in Bangkok and one in Chicago — the gap is too wide. A call has to sit early or late for one side. Early morning in Bangkok is the usual compromise, since that is late afternoon or evening in Chicago.

A note on CST: it can also mean China Standard Time (UTC+8) and Cuba Standard Time (UTC−5). This page means US Central Time.

Indochina Time (ICT) is used in Thailand, Vietnam, Cambodia and Laos

Central Time (CST) is used in Dallas, Houston, Mexico City and Winnipeg
