Nakshatra and Navamsha Calculation Formulas

[Vic DiCara / Vraja Kishor]

In case you are inclined to math, here are some formulas pertaining to calculating nakshatra and navamsha

 

NAVAMSHA:

 

$degrees = (($sign-1)*30)+$degree;

$nav = (floor($degrees/3.33)+1)%12;

 

Take the number of the sign, subtract 1, multiply that by 30 and add the number of degrees progressed in that sign.... then divide that by 3.333, lose the remainder, add one, divide by 12 and take the modulus. That shows the number of the navamsha rashi.

 

NAKSHATRA:

 

$degrees = (($sign-1)*30)+$degree;

$nak = floor($degrees/13.33)+1;

 

Nakshatra is the same method almost exactly... subtract one from the number of a graha's sign. multiply by 30 and add the degrees progressed within the sign. Now with that number, divide by 13.33. Lose the remainder and add one. That's the number (1-27) of the nakshatra.
