If we assume that Jesus Christ was born in what is now known as 1 B.C.E., as some once supposed, then December 31, 2000 (not 1999), will indeed mark the end of the second millennium, and January 1, 2001, the beginning of the third.
فرض کنیم ،‏ در این صورت پایان هزارهٔ دوم ۳۱ دسامبر سال ۲۰۰۰ خواهد بود ،‏ نه ۳۱ دسامبر سال ۱۹۹۹ .‏
