Poland has scheduled its 2026 transition from daylight saving time to winter time for the night of October 24 to October 25. During this shift, clocks will be set back from 03:00 to 02:00.

The timing of the 2026 change is noted as being one day earlier than in previous years. This adjustment occurs amidst a broader European Union debate regarding the potential abolition of bi-annual clock changes. While the EU has considered reforms, the requirement for seasonal shifts remains in effect in Poland.

Health experts have raised concerns regarding the impact of these transitions on human biological rhythms. Experts, including Prof. Marta Jackowska, have warned that such shifts can cause disruptions similar to jet lag, potentially leading to increased risks of traffic accidents, heart attacks, sleep disturbances, and reduced workplace productivity. In response to these concerns, the Polish Sejm is preparing a bill for 2025 that proposes the implementation of permanent summer time.
