Know your Rasi and Nakshatra!

Janma Nakshatra (Birth Star)
Each one of us is born under one of 27 nakshatras.
This is also known as one's janma nakshatra or birth nakshatra.


Some also refer to this as the birth star even though that terminology is not quite precise since a nakshtra can be much more than just one star.


27 Nakshatras in a Great Circle
Imagine a great circle in space and the 27 nakshatras laid out equally on this circle.
Since a circle covers 360 degrees, these 27 nakshatrams cover 360 degrees in space.


So the "space" occupied by one nakshatram is 360 divided by 27 which is equal to 13 degrees and 20 minutes.




 


12 Raasis in the Same Great Circle
Now instead of dividing these 360 degrees by 27 divide them by 12. If you do that, you get 12 raasis.
12 Raasis = 27 Nakshatras!
1 Raasi = 2 and 1/4 Nakshatras


The space occupied by the 12 rashis is the same space occupied by the 27 nakshatras. Thus each one of us has a janma rasi just like we have a janma nakshatra.


You can think of the 12 rasis as another way of grouping the 27 nakshatras.



Since 12 rasis = 27 nakshatras, one raasi = two and a quarter nakshatras (since 27 divided by 12 = 2 and 1/4). In other words, the 27 nakshatras are grouped under 12 rasis at two and a quarter nakshtras per raasi.


As you can see, a nakshatra can occupy a part of one rasi and a part of the next rasi (as laid out in the table below). This is the case for 9 of the 27 nakshatras. These 9 are: Kritika, Mrigasira, Punarvasu, Uttara Phalguni, Chitra, Visaka, Uttarashada, Dhanishta and Poorvabhadra are partly in one rasi and partly in another.


But if each nakshatra is divided into 4 equal quarters, a quarter will never occupy more than one rasi. This higher precision division of each nakshatra into quarters has been done.


Nakshatra Paadham = 4 Quarters of each nakshatra


The space occupied by each naksatra (in the great circle) is divided into four equal quarters.


Since there are 27 nakshatras, there are 108 nakshatra quarters (27 x 4 = 108) in total with each quarter spanning 3 degrees and 20 minutes of the great circle.


Each quarter of each nakshatra will never span two rasis; each quarter will be part of one and only one rasi.


Each such nakshatra quarter is referred to as a Nakshatra Paadham or Nakshatra Pada.


When you hear people make statements such as "My nakshatra is Punarvasu 2nd padham" or "My birth star is Vishaka 4th quarter" and so on, they are referring to this finer division of each nakshatra into quarters.


Finding out your Rasi from your Nakshatram
If you know your janma nakshatra, you can find out your janma rasi from your nakshatram. Click here to do that. Of course, if your nakshatra spans more than one rasi, then use our calculator below to find out which of the two is your rasi.


Finding out your Rasi when you don't know your Nakshatra
If you don't know your janma nakshatra, you have to do a bit more work. Click here to use our calculator to find out your janma nakshatram and janma rasi.
