What BST and MSK Actually Are
BST — British Summer Time
London, Manchester, Birmingham, Glasgow, and the rest of the UK from late March to late October. Standing at UTC+1:00 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, October 25, 2026, to GMT. BST also stands for Bangladesh Standard Time (UTC+6). BDT is the clearer label for that one.
British Summer Time began in 1916 as a wartime fuel-saving measure and has run every year since, making it one of the oldest continuous daylight saving schemes in the world.
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
BST 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, October 25, 2026 unless someone resets it.
Close enough to share a working day
At only 2 hours apart, the two working days overlap almost completely. Scheduling is barely constrained by the difference.
