What ET and MSK Actually Are
ET — Eastern Time
New York, Toronto, Washington DC, Atlanta, Miami, Boston. Standing at UTC-5:00 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 EST.
Eastern Time covers roughly half the US population and, because of that, is the zone most American business defaults to when nobody specifies one.
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
This gap is not fixed
ET 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.
