Decades
A decade () is a period of ten years. Decades may describe any ten-year period, such as those of a person's life, or refer to specific groupings of calendar years. Usage Any period of ten years is a "decade". For example, the statement that "during his last decade, Mozart explored chromatic harmony to a degree rare at the time" merely refers to the last ten years of Wolfgang Amadeus Mozart's life without regard to which calendar years are encompassed. Also, 'the first decade' of a person's life begins on the day of their birth and ends at the end of their 10th year of life when they have their 10th birthday; the second decade of life starts with their 11th year of life (during which one is typically still referred to as being "10") and ends at the end of their 20th year of life, on their 20th birthday; similarly, the third decade of life, when one is in one's twenties or 20s, starts with the 21st year of life, and so on, with subsequent decades of life similarly described by r ...

Millennium
A millennium (plural millennia or millenniums) is a period of one thousand years, sometimes called a kiloannus, kiloannum (ka), or kiloyear (ky). Normally, the word is used specifically for periods of a thousand years that begin at the starting point (initial reference point) of the calendar in consideration (typically the year "1") and at later years that are whole number multiples of a thousand years after the start point. The term can also refer to an interval of time beginning on any date. Millennia sometimes have religious or theological implications (see millenarianism). The word ''millennium'' derives from the Latin ', thousand, and ', year. Debate over millennium celebrations There was a public debate leading up to the Millennium celebrations, celebrations of the year 2000 as to whether the beginning of that year should be understood as the beginning of the “new” millennium. Historically, there has been debate around the turn of previous decades, centuries, and mil ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
2020s
The 2020s (pronounced "twenty-twenties" shortened to "the '20s" and referred to as the twenties) is the current decade, which began on January 1, 2020, and will end on December 31, 2029. The 2020s began with the COVID-19 pandemic — the first reports of the virus were published on December 31, 2019, though the first cases are said to have appeared nearly a month earlier — which caused a global economic recession as well as continuing financial inflation concerns and a global supply chain crisis. Multiple international demonstrations occurred in the early 2020s, including a continuation of those in Hong Kong that started in the late 2010s against extradition legislation, protests against certain local, state and national responses to the COVID-19 pandemic, others around the world against racism and police brutality, more in India against agriculture and farming acts, and, most recently, ones in Sri Lanka, Iran, China, and Russia against various forms of governmenta ...

Century
A century is a period of 100 years. Centuries are numbered ordinally in English and many other languages. The word ''century'' comes from the Latin ''centum'', meaning ''one hundred''. ''Century'' is sometimes abbreviated as c. A centennial or centenary is a hundredth anniversary, or a celebration of this, typically the remembrance of an event which took place a hundred years earlier. Start and end of centuries Although a century can mean any arbitrary period of 100 years, there are two viewpoints on the nature of standard centuries. One is based on strict construction, while the other is based on popular perception. According to the strict construction, the 1st century AD began with AD 1 and ended with AD 100, the 2nd century spanning the years 101 to 200, with the same pattern continuing onward. In this model, the ''n''-th century starts with the year that ends with "01", and ends with the year that ends with "00"; for example, the 20th century comprises the years 19 ...

Roaring Twenties
The Roaring Twenties, sometimes stylized as Roaring '20s, refers to the 1920s decade in music and fashion, as it happened in Western society and Western culture. It was a period of economic prosperity with a distinctive cultural edge in the United States and Europe, particularly in major cities such as Berlin, Buenos Aires, Chicago, London, Los Angeles, Mexico City, New York City, Paris, and Sydney. In France, the decade was known as the '' années folles'' ("crazy years"), emphasizing the era's social, artistic and cultural dynamism. Jazz blossomed, the flapper redefined the modern look for British and American women, and Art Deco peaked. In the wake of the military mobilization of World War I and the Spanish flu, President Warren G. Harding " brought back normalcy" to the United States. The social and cultural features known as the Roaring Twenties began in leading metropolitan centres and spread widely in the aftermath of World War I. The spirit of the Roaring Twenties ...

Units Of Time
A unit of time is any particular time interval, used as a standard way of measuring or expressing duration. The base unit of time in the International System of Units (SI) and by extension most of the Western world, is the second, defined as about 9 billion oscillations of the caesium atom. The exact modern SI definition is "he secondis defined by taking the fixed numerical value of the cesium frequency, , the unperturbed ground-state hyperfine transition frequency of the cesium 133 atom, to be 9 192 631 770 when expressed in the unit Hz, which is equal to s−1." Historically, many units of time were defined by the movements of astronomical objects. * Sun-based: the year was the time for the Earth to revolve around the Sun. Historical year-based units include the Olympiad (four years), the lustrum (five years), the indiction (15 years), the decade, the century, and the millennium. * Moon-based: the month was based on the Moon's orbital period around the Earth. * Earth-based: ...
