Ayanamsa is the longitudinal difference between the sidereal zodiacs or Nirayana and the Tropical zodiacs or Sayana.
So far as the type of difference is concerned, this is the angular difference between the tropical and the sidereal longitudes. Ayanamsa is actually calculated in three different ways. These are Lahiri Ayanamsa calculation, KP Ayanamsa calculation and Raman Ayanamsa calculation.
You might wonder why it is necessary to know the difference between the sidereal and tropical longitudes. Such differences bring out the exact information regarding the position of your birthplace and also the astrological planetary positions. Again, such accurate details about planetary positions are necessary for the generation of a perfect horoscope or natal chart.
Ayanamsa calculator is considered to be very important, It has significance in Vedic astrology. The significance of Ayanamsa calculator can be understood by considering that if the exact birthplace, the time of birth is provided, it helps in the generation of the most accurate horoscope or birth chart for you.

In order to perform an accurate Ayanamsa calculation via an Ayanamsa calculator, you have to fill in your required information in the calculator. An Ayanamsa calculator will give you a detailed chart and information.
Take a look at the following formula to calculate Ayanamsa for a given date is given:
For the beginning of the year:
A = 16.90709 x Year/10000 - 0.757371 x Year/1000 x Year/1000 - 6.92416100010001000
For any other date and month add the following also to get the correct
B = (Month-1 + date/30) X 1.1574074/1000
Ayanamsa = A + B
Let us calculate the Ayanamsa for 15-7-2009 (15th July 2009)
We have year = 2009, month = 7 (July = 7), date = 15
First we will calculate the value of 'A'
A = 16.90709 x 2.009/1000 – 0.757371 x 2.009/1000 x 2.009/1000 - 6.92416
A = 33.96634381 – 3.056810703 - 6.92416
A = 23.9853731
Now we calculate the values of 'B'
Using the formula B above, we get the following
B = 6.5 x 1.1574074/1000= 7.5231481/1000
B = 0.0075231481
Ayanamsa = A + B = 23.9853731 + 0.0075231481 = 23.9928962
Yanamsa is very important for accuracy of horoscope otherwise all predictions can go wrong, Since Ayanamsa also affects the position of planets, it is all the more necessary to be as nearly correct as possible.
Ayanamsa Calculation is the difference between Tropical Zodiac Planetary Position and Sidereal Zodiac Planetary Position.
As earth's precession changes every year, the difference between the tropical zodiac and the sidereal zodiac changes. This difference is called "Ayanamsa" (sidereal difference). The actual Ayanamsa value must be deducted from the tropical length of each planet to get the sidereal length.
Tropical Zodiac in Sanskrit is called as Sayana. Tropical Zodiac plays only a small role in Vedic astrology, 99% of calculations based on the Sidereal Zodiac. This kind of zodiac has the reference point in the stars. The point 0 Aries is interpreted as the beginning of the sign Aries (or the Nakshatra or Star Aswini) in the sky.
We use the Sidereal Zodiac in Vedic astrology. The difference between the Tropical Zodiac and the Sidereal Zodiac is of great importance.
What modern ephemeris gives us is the Tropical or Sayana Planetary Positions. When the Ayanamsa degree is subtracted from the Tropical Planetary Positions we get Nirayana Planetary Positions. This difference varies with time.
The fundamental metric of Sidereal Astrology|East and West|is the Ayanamsa. This value is critical to the definition and calculation of all Astrological Birth Charts methods and techniques in the Sidereal System.
One small change in the value of the Ayanamsa used collaterally impacts all of the succeeding results.It should be made clear that the house positions obtained from Sayana houses, to be subtracted with Ayanamsa degree from the birth date to compute Nirayana Houses.
There is a difference between Western Astrology and Vedic Astrology in casting the Horoscopes or Birth Chart. The fundamental is that there are two systems of astrology – Saayana (Western) and Nirayana(Vedic).
Western horoscopes take Planetary Positions as observed from the sky and plot as Horoscope also called as Sunsign. we subtract from these planetary positions an amount of 'Ayanaamsa' degrees to cast horoscopes – Moonsign – which is not a fixed one and is variable.
what is this 'Ayanamsa'? why should it be subtracted etc.. are different questions. This Ayanamsa increases by an amount of 52 seconds every year. Ayanamsa calculation is of high importance for calculating Planetary Positions, Ascendant Calculation, Divisional charts, Dasas, transits, etc.
Switching the Ayanamsa can result in major changes in Dasa balance or high level Varga charts like Shastiamsa.
