7th millennium

The seventh millennium is the millennium that will start on January 1, 6001 and will end on December 31, 7000.
But those dates only apply using the Gregorian Calendar and count the millennium from the birth of Christ. If we begin at Adam's first day whey he and Eve stepped out of the garden of Eden is different. The Hebrew and Jewish calendars count from them. In the Book of Moses it says that 
"Wherefore teach it unto your children, that all men, everywhere, must repent, or they can in nowise inherit the kingdom of God, for no unclean thing can dwell there, or dwell in his presence; for, in the language of Adam, Man of Holiness is his name, and the name of his Only Begotten is the Son of Man, even Jesus Christ, a righteous Judge, who shall come in the meridian of time. (Moses 6:57)
James E. Talmage writing in his book "Jesus the Christ" said:
"The term 'meridian,' as commonly used, conveys the thought of a principal division of time or space; thus we speak of the hours before the daily noon as ante-meridian (a.m.) and those after noon as post-meridian (p.m.). So the years and the centuries of human history are divided by the great event of the birth of Jesus Christ."
During the seven thousand years of the earth's existence the 'meridian' would be about the middle of the fourth millennium. According to the Jewish Calendar, the birth of Christ occurred in the year 3758.
"The day Christ was born on the Hebrew calendar is 1st Nissan, 3758. This means it was on the 1st day of the month of Nissan in the year of 3758. It was a little over 3-1/2 millenniums after Adam left the Garden of Eden." (Franklin Reid ©2014, 'Lying in a Manger'.)
