According to its etymology, the word Decade comes from the Greek term " Dekas " which means " Ten ". Basically a Decade is a unit of time to measure ten years, empirically adapted by society around the world. The decade is a very simple unit to apply, widely used to define changes of the cultural era since the main forms or styles of life that have been arranged in society have been marked by this unit. One of the most significant uses of the unit of the decade has been the political, governments and their rulers with their way of developing their political plans have imposed specific dates of operation on the social life of nations, the vast majority in decades, some, those who exceed this period are given a dictatorship call, of course this, also depending on the kind of policy applied to the population
Fashion, music, art in its different manifestations and culture in general is also framed in this time format, as many changed with the arrival of new decades, as in a kind of social convention, today we differentiate the decade of the 60's with that of the 70's regarding his music and that of the 80's with that of the 90's with the significant advances in technology.
The Decade is very useful to describe generic situations that, although they have happened in a particular year, leave the sequel to the news for years more, such is the case of the world wars, the second did not last 10 years, however, the destruction And the consequences were such that the countries involved took decades to recover. Another unit created for social purposes is the century, equivalent to one hundred years (100) or ten decades (10), however, this unit is not as useful as the decade to describe specific events, it is a broader unit, which separates entire eras of society. The last decade has been marked by terrorist events, wars and an imminent global climate change, it should be noted that there are countries that have been placed on the map in the last 10 years, especially Latinos and Africans.
