Moscow is 3 hours ahead in January, 2 hours ahead in July
On 15 January 2026, London is 3 hours behind Moscow. On 15 July 2026, London is 2 hours behind Moscow. The gap shrinks in summer for one reason: the UK moves its clocks forward to British Summer Time (BST, UTC+1). Moscow stays on Moscow Standard Time (MSK), UTC+3, all year. Russia has not observed daylight saving time since October 2014.
Winter vs summer: how the gap changes
Winter (UK on GMT, UTC+0): Moscow is 3 hours ahead. When it is 09:00 in London, it is 12:00 in Moscow. This applies from late October to late March.
Summer (UK on BST, UTC+1): Moscow is 2 hours ahead. When it is 09:00 in London, it is 11:00 in Moscow. This applies from late March to late October.
The UK switches to BST on the last Sunday of March and back to GMT on the last Sunday of October. In 2026, the March change falls on 28 March.
Why “Moscow is GMT+3” fails every summer
Many sources say Moscow is GMT+3. That is only correct when the UK is on GMT in winter. In summer, when the UK switches to BST (UTC+1), Moscow is GMT+2. Rely on “Moscow is GMT+3” during July and you will be one hour off.
Use UTC offsets instead. Moscow is UTC+3 year-round. London is UTC+0 in winter and UTC+1 in summer.
Best times to call between Moscow and London
The best overlap is the London morning. In winter you have a 6-hour window. In summer you have a 7-hour window.
| Your time zone | Good time to call Moscow (MSK) | Moscow time |
|---|---|---|
| London (winter, GMT) | 09:00-15:00 London time | 12:00-18:00 Moscow time |
| London (summer, BST) | 09:00-16:00 London time | 11:00-18:00 Moscow time |
Avoid calling Moscow after 15:00 London time in winter, or after 16:00 in summer. You risk catching the Moscow end of day.
For personal calls, aim earlier. Moscow lunch (13:00-14:00) falls at 10:00-11:00 London time in winter and 11:00-12:00 in summer.
