**Ascendant and Hora Lagna : Sum of Longitudes up to 30 Deg**

For reduction to this new span, a new parameter is introduced in the calculation. Here, Longitude of Ascendant and Hora Lagna i.e. स्पष्ट लग्न and स्पष्ट होरा लग्न are used. Also, for the basis of calculation of Hora lagna, the Sun rise is to be considered when the center of the Sun’s disc is visible on the Horizon. (सूर्य बिंबमध्य क्षितिज दर्शन). The option can be set in Jagannath Hora software, easily through preference for Sunrise and Sunset. For our purpose we add the degrees of both (Asc and HL) Lagna. We do not consider the sign i.e. राशि in this summation. We only consider degrees (0 to 30) in this summation.

**Reduction to the Sum of AL and HL**

Now, the sum obtained is to be checked for Limiting Values as follows:

For all Short Life Cases: If Sum is Less than or equal to 17 deg,

For Medium Life Cases: If Sum is Less than or equal to 27 deg / 29 deg

For Long Life Cases: If Sum is Less than or equal to 13 deg / 16 Deg.

The Table -2 shows more clearly the Limiting values for each case. If the sum is larger than the limiting value, it is to be reduced by half i.e. dividing by two **till it is less than or equal to the limiting value.**

For Middle Life cases : M-S-M, S-M-M, L-S-M, S-L-M, M-M-S and M-M-M (64 to 80, 64 to 91) The limiting value is 27 deg. ,It means, for next step calculation, the sum of HL + AL must be reduced to the limiting values. So the sum will be always less than the limiting value before next step. We will call this *Reduced Sum* as **RS**.

**Formula for Correction to Longevity Span **

The basic multipliers for three categories of the Life viz. Short, Medium and Long are 32, 32 and 64 respectively. The reduced sum RS obtained in previous step is to be multiplied by this Number. Further the product is multiplied by 12 and divided by 365. Now, the matter for finding correction to the Life Span is ready. i.e. the step for (आयु-संस्कार) can be written as

Short Life: Life Span Correction : आयु-संस्कार = RS x 32 x 12 / 365

Medium Life: Life Span Correction: आयु-संस्कार = RS x 32 x 12 /365

Long Life: Life Span Correction : आयु-संस्कार = RS x 64 x 12 /365

**Corrected Life Span = Span in Table-2 – ****Life Span Correction ****आयु****–****संस्कार**

The correction is applied to the Span Values obtained from Table-2. This correction , in terms of years, is to be deducted from the Maximum and Minimun span values to make the estimated Life Span more closer. Thus, the New span Values show the years upto which Minimum and Maximum Life Span can be expected.

**EXCEL tool for Benefit of Readers for this Article**

A fully functional Excel Tool has been created by this Editor. The tool can be very easily used to have the Longevity calculation based on this theory. You can download this tool from here. Readers are requested to give feedback for this novel method to the Author and Editor. The Excel Tool is used for calculating Life Span of Our Respected Nadi – Ashtakavarga – Navamsa Fame Late Shri C. S. Patel, who passed away in 2007 at the age of 92 years. The sample image of the calculation by Tool is given below for the benefit of the readers.
