Daylight saving
London next moves its clocks back on 25 October 2026, to UTC+0. Warsaw next moves its clocks back on 25 October 2026, to UTC+1.
Both sides change clocks, but not on the same dates
Both cities observe daylight saving, so the offset between them is stable for most of the year. It is not stable during the weeks when one has changed and the other has not — check the transition dates above before scheduling anything in those windows.
Scheduling across this corridor
Intra-European scheduling is the easy case: most of the continent is within a couple of hours, and the great majority of it changes clocks on the same date, so the relationship between two European cities stays constant all year. The overlap is effectively the whole working day. The exceptions worth knowing are the countries that sit outside Central European Time — the UK and Ireland an hour behind, and the eastern edge of the continent an hour or more ahead.
About London
London is the practical reference point for global scheduling, sitting at UTC in winter and an hour ahead of it in summer. That is precisely why UTC and London time are not the same thing for most of the year, and why "GMT" used loosely between April and October is usually wrong. British Summer Time runs from the last Sunday in March to the last Sunday in October, on the EU schedule rather than the American one.
About Warsaw
Warsaw runs on Central European Time along with Berlin and Paris, and follows the EU clock-change schedule. Poland's position as a major nearshoring destination for Western European and American companies makes it one of the more frequently scheduled-across cities in the region.
