Poland — Europe/Warsaw
About Time in Warsaw
Warsaw operates on Central European Time (IANA: Europe/Warsaw). During standard time, this is CET at UTC+1, shifting to CEST at UTC+2 from the last Sunday of March to the last Sunday of October. Poland follows the EU-wide DST schedule.
Warsaw is 6 hours ahead of New York during EST, 1 hour ahead of London, and on the same time as Berlin, Paris, and most of the EU. At longitude 21.0 E, Warsaw is one of the easternmost major CET cities — significantly east of the timezone's center — meaning solar noon occurs at about 11:40 AM CET, earlier than in most CET cities.
Warsaw's CET timezone has been important for Poland's post-communist economic integration with Western Europe. Sharing a timezone with Germany, France, and the Benelux countries eliminated time barriers to business, helping Warsaw develop into a major outsourcing and shared services hub. The city hosts European operations centers for many multinational corporations, with CET enabling seamless coordination with clients and partners across the EU while also maintaining reasonable overlap with US East Coast business hours in the afternoon.
Time Facts
Warsaw's longitude (21 E) means it is geographically closer to the EET timezone (UTC+2) than to the center of CET, but Poland adopted CET to stay aligned with its western economic partners — resulting in solar noon occurring about 20 minutes before the clock says noon.
The Warsaw Uprising of 1944 began at exactly 5:00 PM local time (CET equivalent) on August 1st — the 'W-Hour' is commemorated annually with a citywide moment of silence and the sounding of air raid sirens.
Poland's software development industry, one of Europe's largest, has benefited from CET alignment — Polish developers can collaborate in real-time with Berlin (same time), London (1 hour back), and New York (6 hours back) during a single workday.
Warsaw's Palace of Culture and Science, the tallest building in Poland, displays a large clock synchronized to Polish atomic time standards maintained by the Central Office of Measures (GUM) in the city.
