When the difference changes
Atlantic Time and Moscow 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, 2026Moscow Time is 6 hours ahead
- November 1, 2026 – March 14, 2027Moscow Time is 7 hours ahead
- March 14, 2027 – onwardsMoscow Time is 6 hours ahead
Periods shorter than a day are not listed. Each zone changes at its own local time, so on a date when both move there are a few hours when the gap is briefly something else.
Daylight saving
Atlantic Time
Clocks go back one hour — 2:00 am becomes 1:00 am local time, and the zone is on AST after that.
Moscow Time
Moscow Time stays on MSK all year, so its offset from UTC never moves.

Scheduling between the two
Working hours overlap from 9:00 am to 12:00 pm ADT, which is 3:00 pm to 6:00 pm MSK. Anything inside that window falls in the normal working day at both ends.
A note on AST: it can also mean Arabia Standard Time (UTC+3). This page means Atlantic Time.
Atlantic Time (ADT) is used in Nova Scotia, New Brunswick and Puerto Rico
Moscow Time (MSK) is used in western Russia. Russia abolished daylight saving in 2011.
