Flavor oscillations of neutral B mesons have been studied with e+e- annihilation data collected at center of mass energies near the [gamma](4S) at the PEP-II asymmetric collider with the BABAR detector. One B⁰ is fully reconstructed in a hadronic decay to a flavor eigenstate. The flavor of the other B in the event is determined using an inclusive tagging algorithm which exploits the correlations between the flavor of the b quark and the charges of its decay products. By fitting the decay-time distribution of the observed mixed and unmixed final states, the oscillation frequency, [Delta]md, is determined to be 0.516 +/- 0.016 (stat.) +/- 0.010 (syst.) ps-l.
