Meisiki is a Japanese Four Pillars calculator for studying natal charts, element counts and luck cycles. It produces charts without fortune interpretations.
Color coding marks stem and branch combinations and clashes, with element counts beside the chart. For a birth on a solar-term transition day, an unknown birth time can be compared across the transition.
Luck cycles extend to age 110 and annual charts to age 120. Chart text can be sent by email.
