Central European Summer Time

Central European Summer Time (CEST) is the standard clock time observed during the period of summer daylight-saving in those European countries which observe Central European Time (UTC + one hour) during the rest of the year. It corresponds to UTC + two hours.

Other names which have been applied to Central European Summer Time are Middle European Summer Time (MEST), Central European Daylight Saving Time (CEDT), and Bravo Time (after the second letter of the NATO phonetic alphabet).

Since 1996 European Summer Time has been observed between 1:00 UTC on the last Sunday of March and 1:00 on the last Sunday of October; previously the rules were not uniform across the European Union.

The following countries and territories use Central European Summer Time.

CEST was used also in the years 1993–1995 in Portugal, 1998–1999 in Lithuania and 2005–2008 in Tunisia. In addition, Libya used CEST during the years 1951–1959, 1982–1989, 1996–1997 and 2012–2013.
