Ask a room in Brussels for the Moscow time difference and you will get one confident answer: two hours. From late October to late March that answer is correct. From late March to late October it is wrong. The gap shrinks to a single hour. The reason is not Moscow moving. It is Brussels.

Moscow runs on Moscow Standard Time (MSK), fixed at UTC+3. Russia abolished daylight saving time in 2014. The clocks do not move.

Brussels alternates. Central European Time (CET, UTC+1) covers late October to late March. Central European Summer Time (CEST, UTC+2) covers late March to late October. The switch lands on the last Sunday of March and the last Sunday of October. In 2026 those dates are 29 March and 25 October.

The gap follows:

Winter (late October to late March): Moscow is 2 hours ahead. 09:00 in Brussels is 11:00 in Moscow.

Summer (late March to late October): Moscow is 1 hour ahead. 09:00 in Brussels is 10:00 in Moscow.

Transition weeks: The offset to Moscow does not change when North American clocks shift. Brussels and Moscow are unaffected by each other’s DST rules. The gap simply follows the Brussels season.

Calls and meetings shift with the season. A 10:00 Brussels call in January puts the Moscow participant at 12:00. The same 10:00 call in July starts at 11:00 in Moscow. Overlap windows narrow or widen. The Best Time to Call Brussels page maps workable windows for any city pair.

Russia spans 11 time zones. Moscow is the reference for European Russia. Kaliningrad sits at UTC+2 year-round, putting it 0 to 1 hour ahead of Brussels depending on the season.

Belgium changes its clocks. Russia does not. If a call falls in late March or late October, pin down the exact Brussels switch date. In 2026, Brussels moves to summer time on 29 March and back to winter time on 25 October. On those nights the offset shifts. The Brussels Time FAQ lists every clock change through 2027.

Why is Moscow always ahead of Brussels?

Moscow sits at UTC+3, further east in the time zone system. Brussels sits at UTC+1 in winter and UTC+2 in summer. A more easterly longitude means an earlier sunrise and a larger UTC offset.

Does Moscow ever use daylight saving time?

No. Russia observed DST until 2014, then locked onto UTC+3 permanently. The clocks have not moved since.

When is the difference 2 hours?

From late October to late March, when Brussels is on winter time (CET, UTC+1) and Moscow stays at UTC+3.

When is the difference 1 hour?

From late March to late October, when Brussels is on summer time (CEST, UTC+2). The gap to Moscow drops to one hour.
