The earliest public release [I know] is September 22, 2007 . Article Clojure is Two! (since October 16, 2009) confirms this as "being the birth" of Clojure (although there have been several dated subsequently releases short versions).
Additionally, Clojure 1.0 annoncement of May 4, 2009 says: "... Clojure represents several years of effort on my part, but has also been deeply formed by the community within 18 months of its publication." This strengthens the date of birth in September-October 2007 and implies that Clojure caused a somewhat long “pregnancy” :-)
Happy coding.
