What CT and MSK Actually Are
CT — Central 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.
Central Time is the widest US zone by land area, stretching from the Gulf coast to the Canadian border, and it also covers Mexico City.
MSK — Moscow Time
Moscow, Saint Petersburg, Minsk. Standing at UTC+3:00 as written, and the region does not change its clocks, so that offset holds all year. Russia abolished daylight saving in 2014, so Moscow stays on UTC+3 all year.
Russia scrapped daylight saving in 2011 by staying permanently on summer time, found the dark winter mornings unpopular, and settled on permanent standard time in 2014.
What This Means in Practice
The date changes mid-working-day
For 1 of the eight hours in a normal CT working day, the equivalent MSK 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
CT changes its clocks and MSK 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.

Frequently Asked Questions
What is the time difference between CT and MSK?
MSK is 8 hours ahead of CT. That is the live figure. Taken strictly as written, the gap between CT and MSK is 9 hours — the two differ because at least one of these regions is currently on daylight saving.
What is 9:00 AM CT in MSK?
9:00 AM CT is 5:00 PM MSK.
What are the best hours to schedule a call between CT and MSK?
Standard business hours in these two zones do not overlap at all, so one side has to work outside the 9-to-5. The most workable window is 7:00 AM to 2:00 PM CT, which is 3:00 PM to 10:00 PM MSK.
Does the difference between CT and MSK change during the year?
