The seasonal time change in Europe is politically contentious, with 84% of EU citizens opposing it. Scientific studies indicate that the hour change disrupts bodily alignment with sunlight, leading to sleep issues. The European Commission attempted to end biannual clock changes, but member states have not reached an agreement. The decision to stop changing clocks involves choosing between winter or summer time, influenced by historical political decisions. A proposal for four time zones based on meridians aims to align time more closely with solar time, but could create new political challenges.
