Gregorian Gregorian Calendar

also known as the Western calendar, or Christian 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.
Because of the Protestant Reformation, however, many Western European countries did not initially follow the Gregorian reform, and maintained their old-style systems.
Britain and the British Empire (including the eastern part of what is now the United States) adopted the Gregorian calendar in 1752.

quaker Quaker Calendar

The Religious Society of Friends (also known in some places as Friends Church or Quakers) is a Christian denomination focusing on the priesthood of all believers, which encompasses a range of belief from evangelicalism to liberalism.
The "plain calendar," sometimes called the "scriptural calendar," differs from what Friends referred to as the "world's calendar" in that it uses numbers to denominate the names of the months and days of the week. The plain calendar does not use names of calendar units derived from the traditional names due to their derivation from pagan deities.
