ave J and R, A(y) can be computed using the following equations.<br />
c = floor( (y - y<sub>z</sub>)/19 ) &nbsp;&nbsp;&nbsp;&nbsp;(5)<br />
k = y - y<sub>z</sub> - 19c &nbsp;&nbsp;&nbsp;&nbsp;(6)<br />
Leap month: No leap month if J(k)=0, a leap month if J(k)=1 &nbsp;&nbsp;&nbsp;&nbsp;(7)<br />
Accumulated months: A(y) = &Delta;A + 235c + R(k) &nbsp;&nbsp;&nbsp;&nbsp;(8)<br />
Here floor(x) denotes the largest integer smaller than or equal to x, <span class="nowrap">y<sub>z</sub></span> is the first year o
