What is Western European Summer Time?
Western European Summer Time (WEST) is a system used in several countries to change their clocks for part of the year. This change is called daylight saving time. The main idea is to shift an hour of daylight from the early morning to the evening. This means the sun sets later, giving people more daylight hours in the evening for activities after school or work.
WEST is exactly one hour ahead of Coordinated Universal Time (UTC). UTC is the main time standard that the world uses to regulate clocks and time. Think of it like the world's time clock.
