  As the Greek and Roman methods of computing time were connected with certain pagan rites and observances, Christians began at an early period to adopt the Hebrew practice of reckoning their years from the supposed period of the creation of the world.
  
  Currently the two dominant dates for creation that exist using the biblical model are about 5500 BC and about 4000 BC. These are calculated from the genealogies in two versions of the Bible, with most of the difference arising from two versions of Genesis. The older dates of the Church Fathers in the Byzantine Era and in its precursor, the Alexandrian Era, are based on the Greek Septuagint. The later dates of the Ussher chronology and the Hebrew calendar are based on the Hebrew Masoretic Text.
  
  The Fathers were well aware of the discrepancy of some hundreds of years between the Greek and Hebrew Old Testament chronology, and it did not bother them; they did not quibble over years or worry that the standard calendar was precise "to the very year"; it is sufficient that what is involved is beyond any doubt a matter of some few thousands of years, involving the lifetimes of specific men, and it can in no way be interpreted as millions of years or whole ages and races of men.
  
  To this day, traditional Orthodox Christians will use the Byzantine calculation of the World Era in conjunction with the Anno Domini (AD) year. Both dates appear on Orthodox cornerstones, ecclesiastical calendars and formal documents. The ecclesiastical new year is still observed on September 1 (or on the Gregorian calendar's September 14 for those churches which follow the Julian calendar). September 2024 marked the beginning of the year 7533 of this era.
