A decade is a period of 10 years. The word is derived from the Ancient Greek: δεκάς, translit. dekas), which means a group of ten. Other words for spans of years also come from Latin: biennium, triennium, quadrennium, lustrum, century, millennium.

The 1920s was a decade of the Gregorian calendar that began on January 1, 1920, and ended on December 31, 1929. In North America, it is frequently referred to as the "Roaring Twenties" or the "Jazz Age", while in Europe the period is sometimes referred to as the "Golden Age Twenties" because of the economic boom following World War I. French speakers refer to the period as the "Années folles", emphasizing the era's social, artistic, and cultural dynamism.

The terms anno Domini (AD) and before Christ (BC) are used to label or number years in the Julian and Gregorian calendars. The term anno Domini is Medieval Latin and means "in the year of the Lord", but is often presented using "our Lord" instead of "the Lord", taken from the full original phrase "anno Domini nostri Jesu Christi", which translates to "in the year of our Lord Jesus Christ".
A century is a period of 100 years. Centuries are numbered ordinally in English and many other languages.
An encyclopedia or encyclopædia is a reference work or compendium providing summaries of knowledge from either all branches or from a particular field or discipline. Encyclopedias are divided into articles or entries that are often arranged alphabetically by article name and sometimes by thematic categories. Encyclopedia entries are longer and more detailed than those in most dictionaries. Generally speaking, unlike dictionary entries—which focus on linguistic information about words, such as their etymology, meaning, pronunciation, use, and grammatical forms—encyclopedia articles focus on factual information concerning the subject named in the article's title.
A number is a mathematical object used to count, measure, and label. The original examples are the natural numbers 1, 2, 3, 4, and so forth. A notational symbol that represents a number is called a numeral. In addition to their use in counting and measuring, numerals are often used for labels, for ordering, and for codes. In common usage, number may refer to a symbol, a word, or a mathematical abstraction.
0 (zero) is both a number and the numerical digit used to represent that number in numerals. The number 0 fulfills a central role in mathematics as the additive identity of the integers, real numbers, and many other algebraic structures. As a digit, 0 is used as a placeholder in place value systems. Names for the number 0 in English include zero, nought (UK), naught (US), nil, or—in contexts where at least one adjacent digit distinguishes it from the letter "O"—oh or o. Informal or slang terms for zero include zilch and zip. Ought and aught, as well as cipher, have also been used historically.
In traditional grammar, a part of speech' is a category of words which have similar grammatical properties. Words that are assigned to the same part of speech generally display similar behavior in terms of syntax—they play similar roles within the grammatical structure of sentences—and sometimes in terms of morphology, in that they undergo inflection for similar properties.
Chronology is the science of arranging events in their order of occurrence in time. Consider, for example, the use of a timeline or sequence of events. It is also "the determination of the actual temporal sequence of past events".
English number words include numerals and various words derived from them, as well as a large number of words borrowed from other languages.
A millennium is a period equal to 1000 years, sometimes called a kiloyear. It derives from the Latin mille, thousand, and annus, year. It is often, but not always, related to a particular dating system.
A Consumer Price Index measures changes in the price level of market basket of consumer goods and services purchased by households.
National Geographic is the official magazine of the National Geographic Society. It has been published continuously since its first issue in 1888, nine months after the Society itself was founded. It primarily contains articles about science, geography, history, and world culture. The magazine is known for its thick square-bound glossy format with a yellow rectangular border and its extensive use of dramatic photographs. Controlling interest in the magazine has been held by The Walt Disney Company since 2019.
The Dictionary of National Biography (DNB) is a standard work of reference on notable figures from British history, published since 1885. The updated Oxford Dictionary of National Biography (ODNB) was published on 23 September 2004 in 60 volumes and online, with 50,113 biographical articles covering 54,922 lives.
Roman currency for most of Roman history consisted of gold, silver, bronze, orichalcum and copper coinage. From its introduction to the Republic, during the third century BC, well into Imperial times, Roman currency saw many changes in form, denomination, and composition. A persistent feature was the inflationary debasement and replacement of coins over the centuries. Notable examples of this followed the reforms of Diocletian. This trend continued into Byzantine times.
An Olympiad is a period of four years associated with the Olympic Games of the Ancient Greeks. Although the Ancient Olympic Games were established during Archaic Greece, it was not until the Hellenistic period, beginning with Ephorus, that the Olympiad was used as a calendar epoch. Converting to the modern BC/AD dating system the first Olympiad began in the summer of 776 BC and lasted until the summer of 772 BC, when the second Olympiad would begin with the commencement of the next games. By extrapolation to the Gregorian calendar, the 3rd year of the 699th Olympiad will begin in (Northern-Hemisphere) mid-summer 2019.
Year zero does not exist in the anno Domini system usually used to number years in the Gregorian calendar and in its predecessor, the Julian calendar. In this system, the year 1 BC is followed by AD 1. However, there is a year zero in astronomical year numbering and in ISO 8601:2004 as well as in all Buddhist and Hindu calendars.
Oceanic art or Oceanian art comprises the creative works made by the native people of the Pacific Islands and Australia, including areas as far apart as Hawaii and Easter Island. Specifically it comprises the works of the two groups of people who settled the area, though during two different periods. They would in time however, come to interact and together reach even more remote islands. The area is often broken down into four separate regions: Polynesia, Micronesia, Australasia, and Melanesia. The former two share a common ancestral culture of the Lapita, while the latter two comprise settlers of the first wave of people into the area. All of the regions in later times would be greatly affected by western influence and colonization. In more recent times, the people of Oceania have found a greater appreciation of their region's artistic heritage.
Web of Science is an online subscription-based scientific citation indexing service originally produced by the Institute for Scientific Information (ISI), later maintained by Clarivate Analytics, that provides a comprehensive citation search. It gives access to multiple databases that reference cross-disciplinary research, which allows for in-depth exploration of specialized sub-fields within an academic or scientific discipline.
