Eastern European Summer Time
Eastern European Summer Time (EEST) is one of the names of the UTC+03:00 time zone, which is 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+02:00) is used.
