We present six time-dependent B⁰_d mixing measurements of {Delta}m_d from the CDF Run I data. The CDF average is {Delta}m_d = .494^±.026_±.026(ps)^-1. We also present a measurement of the CP-violating asymmetry sin(2{beta}) using a sample of B⁰/{anti B}⁰ {yields} J/{psi} K⁰_s decays and report sin(2{beta}) = .79 ⁺⁴¹_-.44.
