The Czech Republic has observed Central European Time since 1979. Until 1993 when Czechoslovakia was separated into the Czech Republic and Slovakia, they also had Central European Time and Central European Summer Time. After the summer months, time in the Czech Republic is shifted back by one hour to Central European Time.[2] Like most states in Europe, Summer time (daylight saving time) is observed in the Czech Republic, when time is shifted forward by one hour, two hours ahead of Greenwich Mean Time.
