Nilakantha's Annual Astrology

To the extent that the previous calculation for the desired day and time is found, the elapsed result from the Rule of ThreeA mathematical method (proportions) to find an unknown fourth value from three known values. should be added to that time; this makes it "clear" or accurate.

The main thing to remember here is that one Zodiac sign consists of 9 quarters of the NakshatrasLunar mansions or star clusters used in Vedic astrology.. The movement through one quarter of a Nakshatra is exactly 3 degrees and 20 minutes. Thus:

• 6 degrees 40 minutes for two quarters
• 10 degrees 0 minutes for three quarters
• 13 degrees 20 minutes for four quarters
• 16 degrees 40 minutes for five quarters
• 20 degrees 0 minutes for six quarters
• 23 degrees 20 minutes for seven quarters
• 26 degrees 40 minutes for eight quarters
• 30 degrees 0 minutes for nine quarters are completed.

This is also the sequence for the NavamshaThe ninth part of a sign, a crucial sub-chart in Indian astrology.. One quarter, or 3 degrees 20 minutes, equals 200 minutes of arc. All these figures are used in the Rule of Three.

Example: The solar return (year-entry) occurs in the year 1897 Samyat 1954, on the 12th day of the dark fortnight of the month of Vaishakha, Saturday, at 13 Ghatis and 54 PalsTraditional units of time: 1 Ghati = 24 minutes; 1 Pal = 24 seconds.. On the previous day, Friday, at 41 Ghatis and 46 Pals, the calculation was at the third quarter of the Revati star. On Monday, the 14th day, at 53 Ghatis and 3 Pals, the calculation is at the fourth quarter of Revati. The difference between these is 3 days, 11 Ghatis, and 17 Pals. From the first calculation to the desired time, the difference is 0 days, 32 Ghatis, and 8 Pals.

Now the Rule of Three is: if a movement of 3 degrees 20 minutes occurs in a time difference of 3 days 11 Ghatis 17 Pals, then how much will occur in a time difference of 0 days 32 Ghatis 8 Pals? One must multiply 3 degrees 20 minutes by 0 days 32 Ghatis 8 Pals and divide by 3 days 11 Ghatis 17 Pals. The process of multiplication and division follows the GomutrikaLiterally "cow's urine path"; a zig-zag method of multiplication used in ancient Indian mathematics. and fraction methods.

For easy understanding, the method is as follows: multiply 3 degrees by 60 and add 20 minutes; the total "body" of the multiplier becomes 200 minutes. For the second amount, 0 days 32 Ghatis 8 Pals: if there were a number in the place of zero, we would multiply by 60 and add 32, but here 32 is simply added to zero. Now, multiplying 32 by 60 gives 1920; adding 8 gives 1928 as the multiplier. Multiplying the two values together results in 385,600. This is divided by the "body" of 3 days 11 Ghatis 17 Pals, which is 11,477. The result is 33 minutes. By multiplying the remainder by 60 and dividing by the divisor, the quotient would be degrees and the remainder minutes. Here, 33 is less than sixty, so it remains as minutes, and degrees are 0. Now, consider that in the third quarter of Revati, 0 degrees 33 minutes 36 seconds...
