Note: The common year numbering system follows the ordinal numbers rather than the cardinal numbers, thus there was no year "zero". The date January 1, 1 CE immediately followed the date December 31, 1 BCE. Thus, while the 2000s began on Saturday, January 1, 2000 CE, the official Third Millennium began on Monday, January 1, 2001 CE.
