Eastern European Summer Time

Eastern European Summer Time (EEST) is one of the names of UTC+3 time zone, 3 hours ahead of Coordinated Universal Time. It is used as a summer daylight saving time in some European and Middle Eastern countries, which makes it the same as Arabia Standard Time, East Africa Time and Moscow Time. During the winter periods, Eastern European Time (UTC+2) is used.

Since 1996 European Summer Time has been observed from the last Sunday in March to the last Sunday in October; previously the rules were not uniform across the European Union.
