European Union countries follow a seasonal clock change schedule twice a year, and for Ukrainians living or working in Poland, this means another transition to winter time under clearly defined 'local' rules. To avoid missing the moment when the clocks 'go back' by one hour, it is important to understand not only the exact date, but also which regulatory document governs the time change in Poland and how it connects to general EU rules.
How the EU Legally Regulates Time Changes
The European Union first legally regulated daylight saving time rules in 1980, when a directive was adopted to coordinate existing national practices for the proper functioning of the single market. Today, the general rules for applying summer time across all member states are defined by a directive that entered into force in 2001. Meanwhile, the exact schedule — the period of summer time and the dates for returning to winter time — is set by a separate document: the European Commission calendar. The newest such document was published in March 2026 and sets the schedule for seasonal changes for 2027–2031.
Universal Time Coordinated (UTC) and Three EU Time Zones
According to the European Commission, the periods of summer time application in the EU are oriented around Coordinated Universal Time (UTC): both the start and end of summer time are fixed at 01:00 UTC. However, the actual 'local' time for changing clocks — on the last Sunday of March and the last Sunday of October — depends on which time zone a specific country belongs to. Overall, there are three standard time zones in the EU, meaning the same UTC date can correspond to different hours on wall and wrist clocks across different countries.
Which Document Regulates Time in Poland
In Poland, the dates and exact times for transitioning to summer time and back are regulated by the Prime Minister's decree of March 4, 2022. It specifies that the abolition of Central European Summer Time involves changing the clock from 3:00 to 2:00, which becomes the starting hour of Central European Time (CET). It is this decree, rather than an abstract EU calendar, that determines exactly what and at what moment the residents and guests of the country do.
When Exactly Clocks Are Changed in Poland in 2026
Based on the 'last Sunday of October' rule and the Polish decree, the transition to winter time in Poland in 2026 will take place on October 25: at 03:00 local time, the clock hands are moved to 02:00. This effectively gives residents and guests of the country an extra hour of sleep that night, while the rest of the day follows standard Central European Time. For Ukrainians planning trips, work shifts, or medical and banking procedures, it is important to check the schedule in advance to avoid mixing up appointment or departure times.
Practical Consequences for Daily Routine
The autumn clock change traditionally shifts the usual rhythm: the body perceives the time change as a noticeable alteration, and adaptation can take from a few days to a couple of weeks. Experts discussing the topic of seasonal time changes advise starting to adjust the schedule in advance — for example, going to bed 15 minutes earlier during the week leading up to the change date and reducing exposure to blue light from screens before sleep. Thus, a few days before October 25, 2026, Ukrainians in Poland should not only remember the date, but also gently prepare their daily routine for the fact that the clocks will go back an hour.
