  The essences of the weak CP violation, the quark and lepton Jarlskog
invariants, are determined toward future model buildings beyond the Standard
Model (SM). The equivalence of two calculations of Jarlskog invariants gives a
bound on the CP phase in some parametrization. Satisfying the unitarity
condition, we obtain the CKM and MNS matrices from the experimental data, and
present the results in matrix forms. The Jarlskog determinant $J^q$ in the
quark sector is found to be $\sim 3.11\times 10^{-5}|\sin\delks|$ while
$J^\ell$ in the leptonic sector is $\sim 2.96\times 10^{-2}|\sin\delksl|$ in
the normal hierarchy parametrization.
