FreeBSD birthday date

[Dmitriy Demidov]

Hi all

I did not found this information on www.freebsd.org and google also did not 
told me any correct date, so I just wanna to make a clear and ask - is there 
any official date of birth for "Beastie" :)

http://www.freebsd.org/releases/
says that it is a "1.0 (November, 1993)"

http://en.wikipedia.org/wiki/Freebsd 
says that: "The first official release was FreeBSD 1.0 in December 1993"

In the same time meetBSD California 2008 is sheduled for November 15th

So, is it that 15.11.1993 is the official birthday date? =)
