Frequently Asked Questions
What is the time difference between CST and MSK?
During standard time, Moscow Standard Time is 9 hours ahead of Central Standard Time.
Is CST the same as Central Time (CT)?
Central Time (CT) is the umbrella term for the zone, while CST and CDT refer to its two seasonal offsets. CST (UTC-6) applies during standard time from November through March, and CDT (UTC-5) applies during Daylight Saving Time from March through November.
Does Mexico City use CST?
Mexico City operates on UTC-6, the same offset as CST, but it does not observe Daylight Saving Time following Mexico's elimination of the practice under a 2022 law. This means Mexico City stays at UTC-6 year-round while US and Canadian Central Time cities shift to UTC-5 each summer.
Does Russia observe Daylight Saving Time?
Russia abolished Daylight Saving Time entirely in 2014, settling permanently on standard time after a contentious experiment with year-round summer time that began in 2011. Moscow Standard Time has remained fixed at UTC+03:00 ever since, with no seasonal clock changes of any kind.
Are MSK and Eastern European Summer Time (EEST) the same?
During summer, countries observing Eastern European Time — including Ukraine, Romania, and Greece — shift to EEST at UTC+03:00, which numerically matches MSK exactly. However, MSK holds at UTC+03:00 year-round, while EEST is a temporary designation that reverts to UTC+02:00 when those countries return to standard time each autumn.
