es. The lunation fraction of a solar term is the time difference between the solar term and its previous lunar conjunction in units of lunar cycles, which is simply the fractional part of L. Take Z11 in <span class="nowrap">N<sub>-130</sub></span> as an example. We have<br />
L = (JD<sub>Z11</sub> - 1646163.5)/29.53085106382979 = 928.0157111207177<br />
lunation fraction of Z11 =  L - floor(L) = 0.01571112207177 &approx; 0.3/19,<br />
which agrees with the calculation above. Since the Julian day of a lunar
