Time in the Czech Republic is Central European Time (Středoevropský čas, SEČ: UTC+01:00) and Central European Summer Time (Středoevropský letní čas, SELČ: UTC+02:00).Daylight saving time is observed from the last Sunday in March (2:00 CET) to the last Sunday in October (3:00 CEST). 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. 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.
The Czech Republic, also known by its short-form name, Czechia, is a landlocked country in Central Europe bordered by Germany to the west, Austria to the south, Slovakia to the east and Poland to the northeast. The Czech Republic covers an area of 78,866 square kilometres (30,450 sq mi) with a mostly temperate continental climate and oceanic climate. It is a unitary parliamentary republic, with 10.6 million inhabitants; its capital and largest city is Prague, with 1.3 million residents. Other major cities are Brno, Ostrava, Olomouc and Pilsen. The Czech Republic is a member of the European Union (EU), NATO, the OECD, the United Nations, the OSCE, and the Council of Europe.
Central European Time (CET), used in most parts of Europe and a few North African countries, is a standard time which is 1 hour ahead of Coordinated Universal Time (UTC). The time offset from UTC can be written as UTC+01:00. The same standard time, UTC+01:00, is also known as Middle European Time and under other names like Berlin Time, Warsaw Time and Romance Standard Time (RST), Paris Time or Rome Time.
UTC+01:00, known simply as UTC+1, is a time offset that adds 1 hour to Coordinated Universal Time (UTC). This time is used in:
In the IANA time zone database the republic is covered by Europe/Prague.
A time zone is a region of the globe that observes a uniform standard time for legal, commercial, and social purposes. Time zones tend to follow the boundaries of countries and their subdivisions because it is convenient for areas in close commercial or other communication to keep the same time.
The Eastern Time Zone (ET) is a time zone encompassing part or all of 22 states in the eastern part of the contiguous United States, parts of eastern Canada, the state of Quintana Roo in Mexico, Panama in Central America, and the Caribbean Islands.
The Pacific Time Zone (PT) is a time zone encompassing parts of western Canada, the western United States, and western Mexico. Places in this zone observe standard time by subtracting eight hours from Coordinated Universal Time (UTC−8). During daylight saving time, a time offset of UTC−7 is used.
Time in the United States, by law, is divided into nine standard time zones covering the states and its possessions, with most of the United States observing daylight saving time (DST) for approximately the spring, summer, and fall months. The time zone boundaries and DST observance are regulated by the Department of Transportation. Official and highly precise timekeeping services (clocks) are provided by two federal agencies: the National Institute of Standards and Technology (NIST) ; and its military counterpart, the United States Naval Observatory (USNO). The clocks run by these services are kept synchronized with each other as well as with those of other international timekeeping organizations.
European Summer Time is the variation of standard clock time that is applied in most European countries in the period between spring and autumn, during which clocks are advanced by one hour from the time observed in the rest of the year, in order to make the most efficient use of seasonal daylight. It corresponds to the notion and practice of daylight saving time to be found in many other parts of the world.
Central European Summer Time (CEST), sometime referred also 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 (UTC+01:00) during the other part of the year. It corresponds to UTC+02:00, which makes it the same as Central Africa Time, South African Standard Time and Kaliningrad Time in Russia.
Time in New Zealand, by law, is divided into two standard time zones. The main islands use New Zealand Standard Time (NZST), 12 hours in advance of Coordinated Universal Time (UTC) / military M (Mike), while the outlying Chatham Islands use Chatham Standard Time (CHAST), 12 hours 45 minutes in advance of UTC / military M^ (Mike-Three).
Moscow Time is the time zone for the city of Moscow, Russia, and most of western Russia, including Saint Petersburg. It is the second-westernmost of the eleven time zones of Russia. It has been set to UTC+03:00 permanently on 26 October 2014; before that date it had been set to UTC+04:00 year-round since 27 March 2011.
Israel Standard Time (IST) is the standard time zone in Israel. It is two hours ahead of UTC (UTC+02:00).
Australia uses three main time zones: Australian Western Standard Time, Australian Central Standard Time, and Australian Eastern Standard Time. Time is regulated by the individual state governments, some of which observe daylight saving time (DST). Australia's external territories observe different time zones.
There are eleven time zones in Russia, which currently observe times ranging from UTC+02:00 to UTC+12:00. Daylight saving time is not used in Russia.
The UTC offset is the difference in hours and minutes from Coordinated Universal Time (UTC) for a particular place and date. It is generally shown in the format ±[hh]:[mm], ±[hh][mm], or ±[hh]. So if the time being described is one hour ahead of UTC, the UTC offset would be "+01:00", "+0100", or simply "+01".
The time zone in Germany is Central European Time and Central European Summer Time. Daylight saving time is observed from the last Sunday in March to the last Sunday in October. The doubled hour during the switch back to standard time is named 2A and 2B.
Azerbaijan Time, or AZT, is a time zone used in Azerbaijan. The standard time zone is four hours ahead of UTC (UTC+04:00). The daylight saving time adjustment, Azerbaijan Summer Time (AZST), which was one hour ahead at UTC+5 was discontinued in March 2016.
Europe spans seven primary time zones, excluding summer time offsets. Most European countries use summer time and harmonise their summer time adjustments; see Summer time in Europe for details.
The only African countries and regions that use daylight saving time are:
Spain has two time zones and observes daylight saving time. Spain mainly uses Central European Time (GMT+01:00) and Central European Summer Time (GMT+02:00) in Peninsular Spain, the Balearic Islands, Ceuta, Melilla and plazas de soberanía. In the Canary Islands, the time zone is Western European Time (GMT±00:00) and Western European Summer Time (GMT+01:00). Daylight saving time is observed from the last Sunday in March to the last Sunday in October throughout Spain.
Cambodia observes UTC+07:00 and does not observe daylight saving time.
Namibia since September 2017 is in the Central Africa Time zone at UTC+02:00, congruous with South African Standard Time.
