INTRODUCTION
The term “Nakshatra” refers to a segment of the zodiac covering an arc of 13°-20'. The zodiac of 360° is thus made up of 27 Nakshatras, viz., 27x13°-20'=360°, making a full circle. Each Nakshatra is given a separate name in Indian astronomy and its Zone or place in heavens can easily be identified during nighttime by the presence of the fixed stars in its Zone. Each Nakshatra is thus made up of a certain number of fixed stars, arranged in a well definable shape and many a time the name given to a Nakshatra is derived from the nature of the shape it presents to the viewer on the earth. The presence of Chandra (the Moon), the fastest moving body of the planetary entities in each of these Nakshatras is one of the important parameters in Oriental astrology. Its entry and exit timings and the duration of the transit in each Nakshatra is calculated and listed in the almanacs published from different parts of the Oriental countries. For example, when a particular day’s Nakshatra is listed in the almanac as “Rohini”, it means that for a major part of the day or at the time of sunrise, Chandra is in the Zone in the heavens represented by “Rohini”. Chandra is thus the long needle of the zodiac clock given by Nature.
DASHA PERIODS
All these 27 Nakshatras have been assigned to the 9 planets (“Grahas”) in Hindu astrology and each planet is supposed to own three Nakshatras. The nine planets considered are (1) Ravi (Sun), (2) Chandra (Moon), (3) Kuja (Mars), (4) Budha (Mercury), (5) Guru (Jupiter), (6) Sukra (Venus), (7) Sani (Saturn), (8) Rahu (Dragon Head), and (9) Ketu (Dragon Tail). In Hindu astrology, each individual’s life span is supposed to come under the spell of these planets at different points of time in life, each spell of the planet lasting for a certain period of time known as “Dasha Period”. The position of Chandra in a Nakshatra during the birth time decides the Birth Dasha Period of the individual. Thus if Chandra is found in “Mrigasira” or “Chitta” or “Dhanista” Nakshatra owned by Kuja, then the Birth Dasha is that of Kuja. After Kuja Dasha, the Dasha Period of another planet starts and the sequence continues until all the planets are covered. The Dasha Periods of the planets are not of same duration. The sequence of Dashas and their duration is (1) Ravi: 6 years, (2) Chandra: 10 years, (3) Kuja: 7 years, (4) Rahu: 18 years, (5) Guru: 16 years, (6) Sani: 19 years, (7) Budha: 17 years, (8) Ketu: 7 years, and (9) Sukra: 20 years making the total life-span as 120 years (“Vimsottari” Dasha). Again each Dasha Period of a planet is divided into 9 “Antardasha” (Sub-Dasha) Periods which are assigned to each of the planets starting with the Dasha Period planet and following the sequence. Antardasha Period of a planet is proportional to its Dasha Period within the Dasha Period of the main planet in such a way that the total duration of the Antardasha Periods of all the planets corresponds to the Dasha Period of the main planet. This can be continued to arrive at still small periods of time intervals within Antardasha and so on. Thus we have Vidasha (Sub-Antardasha), Sukshma (Sub-Vidasha) and Prana (Sub-Sukshma) periods as enunciated by the ancient Rishi Parasara in his Hora Sastra.
In the example given above, after Kuja Dasha, the sequence of Dashas is Rahu, Guru, Sani, Budha, Ketu, Sukra, Ravi and lastly Chandra. Each Dasha Period can be divided into Antardasha Periods and so on. It should be mentioned that the duration of the Birth Dasha Period generally does not pertain to the total duration of the Dasha Period of that planet. It depends on the exact degreecal position of Chandra while transiting in the Nakshatra at the time of birth. As mentioned earlier, the span of each Nakshatra is 13°-20'¢ or 800' arc. This total of 800¢ corresponds to the total Dasha Period of the Planet owning the Nakshatra. If Chandra has already transited through a part of Nakshatra at the time of Birth, the balance Dasha Period of the planet during birth is calculated proportionally from the remaining part of the arc of 800¢. Thus the calculation of Dasha Periods requires the presence of Chandra in the zodiac at a given point of time. That is the duration of a day corresponds exactly to the time taken by Chandra to transit through a Nakshatra. This Nakshatra day defined in this fashion is different from the day that we normally use, viz., 24-hour day or sunrise to sunrise or sunset to sunset. The duration of a Nakshatra day is not constant. It is different in different Nakshatras as well as different in the same Nakshatra depending on the “Tithi” (Ravi-Chandra distance) present on that day. Chandra spends about 28 hours in a Nakshatra around full moon time and about 21 hours around new moon time.
The month of 30 days based on Nakshatra Paddhati is the duration of time Chandra takes to cover an arc in the zodiac described by 30 Nakshatras. This corresponds to 400° (360° for covering 27 Nakshatras and another 40° for the remaining 3 Nakshatras). Thus if one starts counting the beginning of the month, say at Aswini 0°, the month ends when Chandra completes one cycle of 27+3 Nakshatras, viz., the end of “Krithika”. The second month begins when Chandra enters “Rohini” 0°. Continuing this argument, a year of 360 days based on Nakshatra Paddhati corresponds to the time taken by Chandra to cover 360 Nakshatras or 13 cycles of 27 Nakshatra plus 9 more Nakshatras. That is at the beginning of the year, if it is Aswini 0°, then the year ends at Aslesha 0° and the second year begins at Makha 0°. We can extend this logic to the life span and the Dasha Periods of an individual also. If one’s birth Nakshatra is Rohini, this Nakshatra returns exactly after 3 years (or multiples of 3 years). 60 years of that person will be complete when Chandra has completed 60x360/27 = 800 cycles and enters Rohini again. One would see the 1000 full moons if one survives for 75 years (75x360/27 = 1000).
Chandra thus serves as a precise indicator for timing and when a new Dasha Period has to begin, it would not just begin on any day other than one shown by Chandra. Ravi Dasha Period for any one would begin only when the Nakshatra on that day is owned by Ravi (Krithika or Uttara or Uttarashadha). Similarly Chandra Dasha Period begins when the Nakshatra on that day is Rohini or Hasta or Sravana. Similarly even Antardasha and other sub-periods of a planet begin when Nakshatra on that day belongs to that planet.
The sequence of Dashas and Antardashas as envisaged in the Vimsottari Dasha system and the Nakshatras on the first and last day of the Antardasha period can now be calculated based on the logic given above.

I am reminded of a "story" or was it true?
The great mathematician and an astrologer, Bhaskaracharya had a daughter, Leelavathi. Once she reached the marriageable age he looked for a suitable boy and fixed the date for wedding based on the horoscopes of the boy and Leelavathi.On that day the wedding was celebrated but very soon the new bridegroom died of a snake bite.
The Great Bhaskaracharya was stunned and tried to look for the DOSHA either in the horoscopes or the wedding date. He could not get any clue. He recalculated and recalculated and found that the wedding date was the most auspious one. However he could not cahnge the destiny of his only daughter.
One day he was observing the Hour Glass set up in the house for the calculation of time. There he found the nose stud of baby Leelavathi which she accidentally lost in her childhood while looking into the hour glass. Then he realised the DESTINY decided by HIM can not be changed inspite of having excellent knowledge of Astrology
Your comment"...destiny decided by Him...."is bit incorrect!'DESTINY'according to Hindu spirituality is made,built from moment to moment its a eternal and on going process.God is Eternal in His existance ,so He never decide a 'Destiny' in the 'Past'.Rather He decide a 'Destiny' in the 'Eternal Present',that is eternity.
So,to discard Astrological calculations by quoting a sceptic story is not compatible with Jyotish Shastra which is Vetted by 'Eternal Vedas'.Thanks
I am the sort of hombre who enjoys to try brand-new stuff. Presently I'm manufacturing my personalized solar panels. I am doing it all alone without the aid of my men. I am utilizing the internet as the only path to acheive that. I ran across a very awesome site that explains how to make pv panels and so on. The site explains all the steps involved in solar panel construction.
I am not sure about how accurate the information given there is. If some experts over here who have experience with these works can have a peak and give your feedback in the page it would be awesome and I'd really value it, cauze I really passion solar panel construction.
Thanks for reading this. You guys are great.
