Winter Time Is the Same as Standard Time
Mainly Used in Europe
The term winter time is commonly used to replace standard time throughout Europe. For example, when the European Union (EU) wants to scrap DST permanently, member states are asked to decide whether to remain on permanent summer time or permanent winter time.
The term winter time is commonly used in Scandinavia where it is known as “vintertid,” Germany refers to it as “Winterzeit,” and in the Netherlands, they call it “Wintertijd.”
Mostly Countries with DST
Because DST is the practice of setting the clocks forward one hour from standard time (or winter time) during the summer months and back again in the winter months, it is natural to use the term winter time.
However, since more than 60% of the countries in the world use standard time all year, it may only make sense to countries that use, or have historically used, DST.
