It is the 6th of July of 2013. According to Arika Okrent, the writer of In the Land of Invented Languages, Lojban has the most complete grammar of any conlang. Lojban's father was Loglan, which started development in 1955. Lojban began its development in 1987 by a professional staff. In 1997, it was "baselined" or frozen, lasting 5 years until 2002 when speakers became free to create new words and idioms and decide which way the language is heading. The Purple Dream is reality.
