Central European Summer Time (CEST), sometimes referred to as Central European Daylight Time (CEDT), is the standard clock time observed during the period of summer daylight-saving in those European countries which observe Central European Time (CET; UTC+01:00) during the other part of the year. It corresponds to UTC+02:00, which makes it the same as Eastern European Time, Central Africa Time, South African Standard Time, Egypt Standard Time and Kaliningrad Time in Russia.
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).
