An atheist sued the state because the cornerstones of all governmental buildings were marked with the A.D. and the year of the construction.
A.D. usually understood as the abbreviation for Anno Domini.
Of course the politicians from back in the day were part of a world-wide conspiracy to inflict their religious beliefs on the poor downtrodden folks that God has endowed with breath, life and the ability to not believe in Him. So this “idjit” took his issue to court.
In these days of trying to make everyone happy and take into consideration their tender feelings it would seem that perhaps this godless joker might have a point. That would hold water unless you did your homework, which I have done and will share the answers with you. There may be a test on this at a later date, so pay attention.
They are based on different criteria that were important to a culture. It could be based on astronomical observations, lunar cycles, solar cycles, significant historical event beginnings and or religion. The principal astronomical cycles are the day (based on the rotation of the Earth on its axis), the year (based on the revolution of the Earth around the Sun), and the month (based on the revolution of the Moon around the Earth).
|Pope Gregory I|
Since the atheists have never seemed to be able to hold a group meeting and string together a list of timely events into a calendar, well based on the fact that we got tired of waiting for them to do this and went ahead and used the Gregorian calendar. It was already there. What can we say?
The Gregorian calendar is also based on an epoch or a significant historical event that would mark a beginning of a period of time. In this case the birth of Jesus Christ.
This epoch was established by the sixth-century scholar Dionysius Exiguus, who was compiling a table of dates of Easter. An existing table covered the nineteen-year period denoted 228-247, where years were counted from the beginning of the reign of the Roman emperor Diocletian.
Dionysius continued the table for a nineteen-year period, which he designated Anni Domini Nostri Jesu Christi 532-550. Thus, Dionysius' Anno Domini 532 is equivalent to Anno Diocletian 248. In this way a correspondence was established between the new Christian Era and an existing system associated with historical records. What Dionysius did not do is establish an accurate date for the birth of Christ. Although scholars generally believe that Christ was born some years before A.D. 1, the historical evidence is too sketchy to allow a definitive dating.
The Hebrew calendar is a lunisolar calendar. It’s currently 5766 according to the Hebrew calendar. It is based mainly on the cycles of the moon. It start was attributed to the Era of Creation or Era Mundi which corresponds to -3760 October 7th on the Julian calendar.
The National Calendar of India is a formalized lunisolar calendar in which leap years coincide with those of the Gregorian calendar as set by the Calendar Reform Committee in 1957. However, the initial epoch is the Saka Era, a traditional epoch of Indian chronology. Months are named after the traditional Indian months and are offset from the beginning of Gregorian months.
The Chinese calendar is a lunisolar calendar based on calculations of the positions of the Sun and Moon. Months of 29 or 30 days begin on days of astronomical New Moons, with an intercalary month being added every two or three years. Since the calendar is based on the true positions of the Sun and Moon, the accuracy of the calendar depends on the accuracy of the astronomical theories and calculations.
Although the Gregorian calendar is used in the Peoples' Republic of China for administrative purposes, the traditional Chinese calendar is used for setting traditional festivals and for timing agricultural activities in the countryside.
The year -45 has been called the "year of confusion," because in that year Julius Caesar inserted 90 days to bring the months of the Roman calendar back to their traditional place with respect to the seasons.
This was Caesar's first step in replacing a calendar that had gone badly awry. Although the pre-Julian calendar was lunisolar in inspiration, its months no longer followed the lunar phases and its year had lost step with the cycle of seasons Following the advice of Sosigenes, an Alexandrine astronomer, Caesar created a solar calendar with twelve months of fixed lengths and a provision for an intercalary day to be added every fourth year. As a result, the average length of the Julian calendar year was 365.25 days. This is consistent with the length of the tropical year as it was known at the time.
So the next time the local atheist sob sister decides to involve the ACLU and announce that their calendrical rights have been violated because the cornerstone of the courthouse says it was built in A.D. 1920 and they want it to say 1920 C.E., please let them know that they are wrong since it would have to read 5680 C.E to reflect the religious calendar that uses those linguistics.
You may want to remind them that most calendars were designed to reflect the religious mores of a culture and ask them to do a historical review of any atheist formalized calendars. Or they could just look at the A.D. on the cornerstone as an abreviation for Anno Diocletian.
