Twins born right near midnight could have different birthdays

Adding onto this twins born near midnight around 1999 to 2000 could be born in different millenium.

Actually, this millennium began 2001.

Wow I learned something new. I had to search it after reading your comment and it is indeed 2001. www.timeanddate.com/counters/mil2000.html

When did the 3rd millennium and 21st century begin: on New Year's Day 2000 or 2001? Do we count from year 1 or year 0 AD? What century are we in?

Yeah, most people get it confused with the Willenium which did end in 1999.

Nice I did not know the fresh prince made an album called Willenium.
