Yes, I know there's a debate going on as to whether the millennium began on January 1st 2000 or whether it begins on January 1st 2001. I know there are those with great mathematical skills and historical interpretations who say the millennium doesn't begin until 2001. But if we began this count based on the birth of Christ, then it's like watching the moon. The People did not only acknowledge the full moon, we also considered the first thin sliver of the moon. And we don't count the beginning of a child's life on their first birthday, but from the moment a child draws his first breath.
Some People even count from the time the child moves in the womb.
The Hebrew year is 5760. The Hindus have their own year, the Mayans theirs. To Native people, time is relative. Indigenous peoples of the world did not see time as a line that began here and ended there. Life, and time, came in cycles, like the seasons.
