How many time zones does Russia span?

Eleven, more than any other country on a single landmass - so when Moscow is having breakfast, Kamchatka is going to bed. France technically has twelve, but only by counting overseas territories scattered around the world; Russia's are contiguous.

The practical effects are strange. The trans-Siberian railway ran on Moscow time along its entire length for decades regardless of where the sun was, so a timetable in Vladivostok showed departures seven hours out of step with the daylight outside, and passengers simply learned to do the arithmetic. It moved to local time only in 2018.

Russia has also changed its mind about daylight saving repeatedly and disruptively. It abolished the clock change in 2011 and kept permanent summer time, which meant Moscow sunrises after ten in the morning through the winter; three years of complaints later it switched to permanent winter time instead. Several regions have separately shifted zones since - it is one of the few countries where what time it is has been a live political question in the last decade.
