The BABAR detector at the PEP-II asymmetric B Factory at SLAC collected a sample of 23 x 10{sup 6} B{bar B} pairs in the years 1999 and 2000. Using this data sample, we measure the amplitude of the time-dependent CP-violating asymmetry in neutral B decays to the CP eigenstates J/{psi} K{sub S}{sup 0}, {psi}(2S) K{sub S}{sup 0} and J/{psi} K{sub L}{sup 0}. We find a value of sin2{beta} = 0.34 {+-} 0.20(stat) {+-} 0.05(syst). We also present preliminary measurements of the B{sup 0}{bar B}{sup 0} oscillation frequency and of the lifetimes of charged and neutral B mesons.
