Western European Time

Western European Time (WET) is the time zone covering parts of western and northwestern Europe, including the following countries and regions:

Time zones of Europe: blue - GMT or Western European Time, red - Central European Time, green - Eastern European Time, khaki - Moscow Time.

During winter months, WET corresponds to Universal Time (UTC); however in the summer, most (but not all) of the above places move one hour ahead to Western European Summer Time (UTC+1). Officially the Republic of Ireland is on UTC+1, but goes to UTC in winter, and for all practical purposes uses the same time as the United Kingdom.

UTC (sometimes called Zulu time or Z time and formerly called Greenwich Mean Time) also covers part of west Africa:
