This is not an easy question to answer. The internet wasn't built so much as it developed and grew from the initial Defense Advanced Research Projects Agency (DARPA) idea of the ARPANET (Advanced Research Projects Agency Network). ARPANET was initialized September 1969 at UCLA, and connected to Stanford Research Institute, UC Santa Barbara, and the University of Utah by October. Bob Kahn from DARPA was perhaps the first to actually suggest the open network architecture idea of the "Internet" in 1972. Working with Vint Cerf in 1973, Kahn began working on the protocol designs that would make Internetting possible. Kahn/Cerf's resulting TCP/IP was initiated in 1973 by contract from DARPA to Ray Tomlinson at BBN, Vint Cerf at Stanford, and Peter Kirstein at UCL, and brought on line later that year.
So, the closest we can get to an actual date is that incident in 1973. Access sites were limited then, but it was publically available.
The Internet service were started for services by the government later it was released for public uses.
