Common Era, abbreviated as CE, is a designation for the world's most commonly used year-numbering system.[1][2] The numbering of years using Common Era notation is identical to the numbering used with Anno Domini Anno Domini and Before Christ (abbreviated as BC or B.C.) are designations used to number years in the Julian and Gregorian calendars. The calendar era to which they refer is based on the traditionally reckoned year of the conception or birth of Jesus, with AD denoting years after the start of this epoch, and BC denoting years before the start of (BC/AD) notation, 2010 being the current year in both notations and neither using a year zero A Year zero does not exist in the widely used Gregorian calendar or in its predecessor, the Julian calendar. Under those systems, the year 1 BC is followed by AD 1. However, there is a year zero in astronomical year numbering and in ISO 8601:2004 (where it coincides with the Gregorian year 1 BC) as well as in all Buddhist and Hindu calendars.[3] Common Era is also known as Christian Era[4] and Current Era,[5] with all three expressions abbreviated as CE.[6] (Christian Era is, however, also abbreviated AD, for Anno Domini.[7]) Dates before the year 1 CE are indicated by the usage of BCE, short for "Before the Common Era", "Before the Christian Era", or "Before the Current Era".[8] Both the BCE/CE and BC/AD notations are based on a sixth-century estimate for the year in which Jesus Jesus of Nazareth , also known as Jesus Christ, is the central figure of Christianity, which views him as the Messiah foretold in the Old Testament, with most Christian denominations believing him to be the Son of God who was raised from the dead. Islam considers Jesus a prophet and also the Messiah. Several other religions revere him in some way was conceived or born, with the common era designation originating among Christians in Europe at least as early as 1615 (at first in Latin Latin is an Italic language originally spoken in Latium and Ancient Rome. With the Roman conquest, Latin was spread to countries around the Mediterranean, including a large part of Europe. Romance languages, such as Aragonese, Corsican, Catalan, French, Italian, Portuguese, Romanian, and Spanish, are descended from Latin, while many others,).[9]
The Gregorian calendar The Gregorian calendar is the internationally accepted civil calendar. It was introduced by Pope Gregory XIII, after whom the calendar was named, by a decree signed on 24 February 1582, a papal bull known by its opening words Inter gravissimas. The reformed calendar was adopted later that year by a handful of countries, with other countries, and the year-numbering system associated with it, is the calendar system with most widespread usage in the world today. For decades, it has been the de facto global standard, recognized by international institutions such as the United Nations The United Nations Organization or simply United Nations (UN) is an international organization whose stated aims are facilitating cooperation in international law, international security, economic development, social progress, human rights, and the achieving of world peace. The UN was founded in 1945 after World War II to replace the League of and the Universal Postal Union The Universal Postal Union is an international organization that coordinates postal policies among member nations, and hence the worldwide postal system. Each member country agrees to the same set of terms for conducting international postal duties. Universal Postal Union's headquarters are located in Berne, Switzerland. There are many names in many languages used to designate this year-numbering system that originated in Western Europe. Common Era notation has been adopted in several non-Christian cultures, by many scholars in religious studies and other academic fields,[10][11] and by others wishing to be sensitive to non-Christians,[12] because Common Era does not explicitly make use of religious titles for Jesus, such as Christ and Lord, which are used in the BC/AD notation.[10][13][14][15]
