Yes, the year 2000 marked the beginning of the new millennium. The confusion often arises from the different ways to define a millennium. Strictly speaking, since the Gregorian calendar starts at 1 AD, without a year zero, the first millennium would have spanned from 1 AD to 1000 AD, making the second millennium from 1001 AD to 2000 AD, and thus, the third millennium began January 1, 2001. However, culturally and commonly, the year 2000 was celebrated worldwide as the start of the new millennium.
