Gregorian Calender and its History

Gregorian calendar

The Gregorian calendar , also called the Western calendar and the Christian calendar , is internationally the most widely accepted and used civil calendar . [ 1 ] [ 2 ] [ 3 ] It has been the unofficial global standard for decades, adopted for pragmatic interests of international communication, transportation, and commercial integration, and recognized by international institutions such as the United Nations and the Universal Postal Union . [ 4 ] The calendar was a reform in 1582 to the Julian calendar . [ 5 ] The motivation for the reform was to bring the date for the celebration of Easter to the time of the year in which the First Council of Nicaea had agreed upon in 325. Because the spring equinox was tied to the celebration of Easter, the Roman Catholic Church considered this steady movement in the date of the equinox undesirable.

December ( i / d iː ˈ s ɛ m b ər / dee- SEM -bər ) is the twelfth and last month of the year in the Julian and Gregorian Calendars and one of seven months with the length of 31 days .
