Flag

a "World" flag does not exist, but the United Nations (UN) flag -- adopted on 7 December 1946 -- has sometimes been used to represent the entire planet; the flag displays the official UN emblem in white on a blue background; the emblem design shows a world map in an azimuthal equidistant projection centered on the North Pole, with the image flanked by two olive branches; blue was chosen to represent peace, in contrast to the red usually associated with war; the map projection includes all the continents except Antarctica

note 1: the flags of 12 nations -- Austria, Botswana, Georgia, Jamaica, Japan, Laos, Latvia, Micronesia, Nigeria, North Macedonia, Switzerland, and Thailand -- have no top or bottom and may be flown with either long edge on top

note 2: the most common colors found on national flags are as follows: red (~75%), white (~70%), and blue (~50%); these three colors are so prevalent that there are only two countries, Jamaica and Sri Lanka, that do not include one of them; the three next most popular colors are yellow/gold and green (both ~45%) and black (~30%)

note 3: flags composed of three colors are by far the most common type and, of those, the red-white-blue combination is the most widespread

time difference

there are 21 world entities (20 countries and 1 dependency) with multiple time zones: Australia, Brazil, Canada, Chile, Democratic Republic of Congo, Ecuador, France, Greenland (part of the Danish Kingdom), Indonesia, Kazakhstan, Kiribati, Mexico, Micronesia, Mongolia, Netherlands, New Zealand, Papua New Guinea, Portugal, Russia, Spain, United States note 1: in some instances, the time zones pertain to portions of a country that lie overseas note 2: in 1851, the British set their prime meridian (0° longitude) through the Royal Observatory at Greenwich, England; this meridian became the international standard in 1884 and thus the basis for the standard time zones of the world; today, GMT is officially known as Coordinated Universal Time (UTC) and is also referred to as "Zulu time"; UTC is the basis for all civil time, with the world divided into time zones expressed as positive or negative differences from UTC note 3: each time zone is based on 15° starting from the prime meridian; in theory, there are 24 time zones based on the solar day, but there are now upward of 40 because of fractional hour offsets that adjust for various political and physical geographic realities; see the Standard Time Zones of the World map included with the World and Regional Maps

daylight saving time

some 67 countries -- including most of the world's leading industrialized nations -- use daylight savings time (DST) in at least a portion of the country; China, Japan, India, and Russia are major industrialized countries that do not use DST; Asia and Africa generally do not observe DST, and it is generally not observed near the equator, where sunrise and sunset times do not vary enough to justify it; some countries observe DST only in certain regions; only a minority of the world's population -- about 20% -- uses DST

Legal system

the legal systems of nearly all countries are modeled on elements of five main types: civil law (including French law, the Napoleonic Code, Roman law, Roman-Dutch law, and Spanish law), common law (including English and US law), customary law, mixed or pluralistic law, and religious law (including Islamic sharia law); an additional type of legal system -- international law -- governs the conduct of independent nations in their relationships with one another

Dependent areas

Australia dependencies: Ashmore and Cartier Islands, Christmas Island, Cocos (Keeling) Islands, Coral Sea Islands, Heard Island and McDonald Islands, Norfolk Island (6) France dependencies: Clipperton Island, French Polynesia, French Southern and Antarctic Lands, New Caledonia, Saint Barthelemy, Saint Martin, Saint Pierre and Miquelon, Wallis and Futuna (8) New Zealand dependency: Tokelau (1) Norway dependencies: Bouvet Island, Jan Mayen, Svalbard (3) United Kingdom dependencies: Anguilla; Bermuda; British Indian Ocean Territory; British Virgin Islands; Cayman Islands; Falkland Islands; Gibraltar; Montserrat; Pitcairn Islands; Saint Helena, Ascension, and Tristan da Cunha; South Georgia and the South Sandwich Islands; Turks and Caicos Islands (12) United States dependencies: American Samoa, Baker Island, Guam, Howland Island, Jarvis Island, Johnston Atoll, Kingman Reef, Midway Islands, Navassa Island, Northern Mariana Islands, Palmyra Atoll, Puerto Rico, Virgin Islands, Wake Island (14)

Executive branch

note

note 1: Andorra and the Holy See (Vatican) are also monarchies of a sort, but they are not ruled by royal houses; Andorra has two co-princes (the president of France and the bishop of Urgell) and the Holy See is ruled by an elected pope note 2: the UK sovereign is also the monarch for the 14 Commonwealth countries (including Australia, Canada, Jamaica, New Zealand)

chief of state

there are 27 countries with royal families in the world: most are in Asia (13) and Europe (10), three are in Africa, and one in Oceania; monarchies by continent are as follows: Asia (Bahrain, Bhutan, Brunei, Cambodia, Japan, Jordan, Kuwait, Malaysia, Oman, Qatar, Saudi Arabia, Thailand, United Arab Emirates); Europe (Belgium, Denmark, Liechtenstein, Luxembourg, Monaco, Netherlands, Norway, Spain, Sweden, United Kingdom); Africa (Eswatini, Lesotho, Morocco); Oceania (Tonga)

National heritage

note

note: a summary of each country's UNESCO World Heritage sites can be found in the national heritage data field, under the Government category for the country

total World Heritage Sites

1,223 (952 cultural, 231 natural, 40 mixed) (2024)

Legislative branch

230 political entities have legislative bodies; of these, 144 are unicameral (a single “house”) and 86 are bicameral (both upper and lower houses); 33 territories, possessions, or other special administrative units have their own governing bodies

National anthem(s)

note

note: the first anthem to be officially adopted (1795) was "La Marseillaise" (The Song of Marseille) of France; Japan claims to have the shortest anthem, "Kimigayo" (The Emperor's Reign), that consists of 11 measures; Japan's anthem has the world's oldest lyrics, dating to the 10th century or earlier; Greece has the anthem with the longest lyrics, "Ymnos eis tin Eleftherian" (Hymn to Liberty), with 158 stanzas; Uruguay has the anthem with the longest musical score, "Himno Nacional" (National Anthem of Uruguay), with 105 bars (almost five minutes)

title

almost every country has a national anthem (and Denmark and New Zealand have two); most anthems have lyrics, which are usually in the official language or the most common language of the country; countries with more than one official language sometimes offer several versions

Administrative divisions

197 countries, 69 dependent areas and other entities

International law organization participation

all UN members are parties to the statute that established the International Court of Justice (ICJ) or World Court; as of June 2025, 125 countries have also ratified or acceded to the Rome Statute of the International Criminal Court (ICCt), the treaty that established the ICCt (see the reference guide on International Organizations and Groups for differences between the ICJ and ICCt mandates)
