In the European Union, Summer Time begins and ends at 1:00 a.m. Universal Time (Greenwich Mean Time). It begins the last Sunday in March and ends the last Sunday in October. In the EU, all time zones change at the same moment.

For many Europeans, Summer Time marks the end of school, brings warmer temperatures and longer days, and fosters an atmosphere of relaxation.

Like Daylight Saving in other nations, the end of Summer Time brings back school days, cooler temperatures, shorter days, and the approach of the winter holidays.
