What is HKT in CST?
Central Time is 13 hours behind
Hong Kong Time is on UTC+8:00 and Central Time is on UTC−5:00 right now. Central Time is on daylight saving, so its clocks read CDT. The gap changes during the year — see below.

When the difference changes
Hong Kong 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:
- Now – November 1, 2026Central Time is 13 hours behind
- November 1, 2026 – March 14, 2027Central Time is 14 hours behind
- March 14, 2027 – onwardsCentral Time is 13 hours behind
Periods shorter than a day are not listed: both zones change at 2am in their own local time, so there are a few hours on each transition date when the gap is briefly something else.
Daylight saving
Hong Kong Time
Hong Kong Time stays on HKT all year, so its offset from UTC never moves.
Central Time
Clocks go back one hour at 2am local time, becoming CST.

Scheduling between the two
There is no overlap between a nine-to-six working day in Hong Kong and one in Chicago — the gap is too wide. A call has to sit early or late for one side. Early morning in Hong Kong 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.
Central Time (CDT) is used in Dallas, Houston, Mexico City and Winnipeg
