What HKT and CST Actually Are

HKT — Hong Kong Time

Hong Kong and Macau. Standing at UTC+8:00 as written, and the region does not change its clocks, so that offset holds all year.

Hong Kong used summer time on and off until 1979, when it stopped for good. Proposals to bring it back have surfaced periodically and never carried.

CST — Central Standard Time

Chicago, Houston, Dallas, Mexico City, Winnipeg. Standing at UTC-6:00 as written, and the region does change its clocks, so its live offset moves by an hour twice a year. The next change is on Sunday, November 1, 2026, to CST. CST also stands for China Standard Time (UTC+8) and Cuba Standard Time (UTC-5). This page covers the North American one.

Saskatchewan sits inside the Central zone but never changes its clocks, so it matches CST in winter and its neighbors' MDT in summer.

What This Means in Practice

The date changes mid-working-day

For 4 of the eight hours in a normal HKT working day, the equivalent CST time falls on a different calendar date. Anything scheduled in that stretch needs the date checked as well as the time, or a Tuesday call quietly becomes a Wednesday one at the other end.

This gap is not fixed

CST changes its clocks and HKT does not, so the difference between them moves by an hour twice a year. A recurring meeting set now will drift for one side from Sunday, November 1, 2026 unless someone resets it.

Nearly opposite sides of the clock

At 13 hours apart, one side's morning is the other side's night. Handing work over at the end of a shift usually beats trying to get both parties in the same call.
