(Ms – Mean Anomaly of the Sun; Mm – Mean Anomaly of the Moon; Ls – Mean Longitude of the Sun; Lm – Mean Longitude of the Moon; D = Lm – Ls ( Thidhi); Nm – Node of the Moon. These values are Sidereal or Nirayana )
14 Kendras are to be made and 14 trignometric corrections are to be given, according to astronomical savants. These 14 reductions are mandatory and only after these reductions can we get the true longitude of the Moon.
| First Kendra | Sin ( Ms + 180 ) * 658 |
| Second Kendra | Sin ( Lm – Ls ) * 121 |
| Third Kendra | Sin ( 2*D – Mm ) * 4467 |
| Fourth Kendra | Sin ( 2*D + 6 Signs ) * 2145 |
| Fifth Kendra | Sin 1* 85 |
| Ninth Kendra | Sin ( 2*Ls – Nm ) * 81 |
| Tenth Kendra | Sin ( Mm – Ms )* 73 |
| Eleventh Kendra | Sin ( 2*D + Mm ) * 60 |
| Twelfth Kendra | Sin ( 2*Mm – 2 D + 180 ) * 42 |
| Thirteenth Kendra | Sin ( 4*D – Mm ) * 35 |
| Fourteenth Kendra | Sin ( 4*D – 2*Mm +180)* 30 |
