Introduction:

In Hindu Mythology, Nakshatras are considered to be 27 wives of moon and they are also the daughters of Daksha Prajipat, whom Lord Brahma has given the duty to help the world. In Hindus the calendar is based on the moon signs. The important festivals like “Holi” and “Diwali” are celebrated based on the moon’s Nakshatras.

The Zodiac is divided into 360 degrees and since there are 27 Nakshatras in the total so we divide 360 Degrees into equal divisions.

For example, 360 / 27 = 13 Degrees and 20 Minutes.

Mathematical Analysis to find a Nakshatra:

To find a Nakshatra a planet falls in

N = {(Rasi * 30) + (Degrees of the Planet)} / 27 + 1

So each Nakshatra is of 27 Divisions.

Now each Nakshatra is divided into 4 parts,

So each pada (part) of a Nakshatra is equal to 13 D 20 M / 4 = 3 D 20 M (Where D is Degrees and M is Minutes)

Some terms which will be used are ‘N’ = Nakshatra; R = Rasi; D = Degrees; M = Minutes; P = Pada (part).

Thus, 27 N = 12 R. Therefore, R = 9/4 N...(i)

Also, as we know that Nakshatra is also divided into 4 parts i.e. N = 4P …(ii)

Thus, R = 9 P …(iii)

As we know that 30 D form a Rasi which means 30 D = 9 P wide  (iii)

Now, D = 3 /10 P …(iv)

Now we consider the longitude of the planet to be broken down into ‘R’ and ‘D’.

I.e. if in the horoscope of a person the sun is say 66 Degrees.

Then Sun has traversed 2 Rasis and 6 Degrees in the Zodiac.

For getting the total number of Nakshatras padas we will add (iii) and (iv),

Thus N = (9 R + 3/10 D) / 4 …because N = 4 P

To this we will add one if we don’t consider the fraction (that means the star has already crossed N Nakshatras and has traversed the fraction in the next Nakshatra)

So our Formula is N = [{9 * (Rasi traversed)   + 3/10 * (Degrees)} / 4] + 1 ….(v)

N = [{9 * (Rasi traversed)   + 3/10 * (Degrees)} / 4] + 1

Here N is the Number of Nakshatra. I.e. 1 for Aswini , 2 for Bharani , …….27 for Revati

Example,

Suppose the Sun is at 66 Degrees which is equal to 2 R + 6 D (for we know that 30 Degrees is equal to a Rasi)

Now applying the formula,

N = [{9*(2) + 3/10 (6)} / 4] + 1. …Replacing ‘R’ by 2 and 6 by ‘D’

N = [{18 + 18/10} / 4] + 1

N = [{18 + 1.8} / 4] + 1

N = {19.8 / 4} + 1  ….Now we will leave the fraction and keep the exact number divisible by 4 and also lesser than that number

N = {16 / 4} + 1

N = 4 + 1 = 5

Thus, we say that the planet is in Mrigasira Nakshatra.
