(Balakanda)||Phalguna-march- april||Simha, Kanya||Both the stars are at same time distance from Poorva Phalguni. If a single star has to be identified as Uttara Phalguni, then 94 b Leo/SAO 119076 / HD 102870 is the best candidate, despite Denebola being brighter.

|Swati||1||Vaayu / Rahu||Tula||There are some scholars who have argued that Arcturus is Swati. Arcturus is located in ‘Bootes’ constellation and is identified as SAO-10094/HD-124893/16-Bootes of brightness +1.24. However, Arcturus is at 19 N degrees where as northern limit of moon traverse (8 S to 18 S) band is -8 degrees. Hence the star Arcturus is located 27 to 37 degrees away, north from moon traverse band, hence can not be seriously considered, as being pointed to by Moon. This 27 degrees is the distance between two Nakshtra’s and too large an error. If we accept moon visits the Arcturus mansion, all our identifications become questionable. The Arcturus mansion located in Bootes constellation is nowhere near Tula (Libra) or Vrishchika. Even 5000 years ago, the location of that constellation was far away from moon traverse band. Hence SAO-139824/HD 124850 /99i Vir, also called Syrma by Arabs is the best candidate for Hastaa. This Nakshatra is 45 minutes or about 12 degrees (E-W) away from Chitra. It is bright enough to have been given a name by Arab astronomers.|
|Vishaaka||2||Indraagni / Guru||Gautama Buddha||VaisakhaMay-June||Tula, Vrischika||If one star has to be chosen as Vishaaka in Tula Raashi, it is 92a2Libra, identified as SAO 158840 or HD 130481. The brightness is +2.75. It has been called, Zubenelgenubi by Arabs. Vishaaka pair is 45 minutes or 11(E-W) degrees away from Swati. Though Zubeneschemele is a little brighter, it is a little away from moon traverse band. Vishaaka is right in the middle of the moon traverse band. Guatama Buddha was born, received enlightenment, and died on the full moon day of Vishaka when full moon was on this nakshatra.|
|Anooradha||4||Mitra / Sani||Vrischika||If a single star has to be identified as Anooraadha then the best candidate is 7d-Sco/SAO 184014/HD 143275. Anooraadha is 1 hour 10 minutes or 17 degrees (E-W) away from Vishaaka. Anooradha is also called Dschubba by Arabs.|
|Jyeshta||3||Indra / Budha||Oldest Star||JyeshtaJune-July||Vrischika||If a single star has to be identified as Jyeshta, then the best candidate is 21 a Sco/SAO 184415/HD 148478. Jyeshta is 30 minutes or 8 degrees (E-W) away from Anooraadha. The brightness of Jyeshta is a high +1.08. Antares|
|Vichruta||11||Moola||Pitru / Ketu||Vishnu||Dhanus||
If one star is to be identified as Moola, then the best candidate for Moola or Vichruta Nakshatra is 42 q OPH from Ophichius zodiac of the European system. It falls in the star band and is 50 minutes or 13 degrees (E-W) away from Jyeshta. Its brightness is +3.28. Arab Sabik is another strong candidate for Moola with +2.43 brightness and is also 13 degrees from Jyeshta.
Moola or Vichruta has been extensively referred to in Atharveda Kaanda 2,Kaanda 3 and kaanda 6 (Ref 2). Vichruta, stands for darkness and Moola carries an adjective Arishta. This word has two meanings, one standing for sweet and second associated with bad associated with death. Astronomically, Moola is in line with Milkiway galactic center.? In modern astronomy, there have been conjectures of a black hole at the center of our Milkiway. This area of sky is visually dark because large amount of matter is presumed to exist around the center of the Galaxy
|Aashada||2||Purvashada||Aapah / Sukra||AshadaJuly-August||Dhanus||If one star is to be identified as Poorvaashadha, it is 34 aSag, which has an Arab name Nunki. Its brightness is +2.06. There are other stars nearby and one which has a brightness of 1.8. But it is far away from the moon traverse band, and hence is not a good candidate for Poorvaashada. Poorvaasaahda is 80 minutes or 20 (E-W) degrees away from Moola.|
|Aashada(Abhijit)||3||Uttarashada||Vishvedeva / Surya||Dhanus, Makara||If one star is to be identified for Uttaraashada, it is the twin star 5a/6a2 both in Capricorn Zodiac. They are of brightness 4.24 and 3.56.Together the pair appear as one star. The SAO identities are SAO-163422/163427 or HD -192876/192947. There is a large gap between Poorvaashada and Uttaraashaada of nearly 22 degrees (E-W). There are no likely candidate stars for Uttaraashaada in the 22 degrees in the moon traverse band or near by. Arabs call this as Geidi associated with slaughter of sheep.|
|Shrona||3||Shravana||Vishnu / Chandra||Sravana Kumara, may have been named after this nakshatram||SravanaAugust – September||Makara||Krishna’s birth in Sravana Masa. Lava Kusa were born on Sravana Pournami, also known as Dandhyala Pournami. Satrughna took control of Mathura in Sravana Masa||If one star is to be identified as representing Shravana, it is clearly 49d-cap of brightness+2.83 identified as SAO-164644 and HD-207098. It is 30 minutes or 8 degrees (E-W) away from Uttarashada, which is a part of Makara Raashi. Arabs also call Shravana as Deneb Al Geidi.|
|Shravishta||4||Dhanishta||Vasu / Kuja||Makara, Kumbha||If one star is to be identified as representing Dhanishta, it is clearly 55z of brightness +3.66 identified as SAO-146107 and HD-213051. From a distance point of view this star is 45 minutes or about 12 degrees (E-W) away from Shravana.|
|ShathaBhishaja||100||Indra / Rahu||Kumbha||Shatabhishaja Nakshatra is defined to be a star mansion of 100 stars. Shata is undred and bhishaja stands for medical doctor. The significance of later is not apparent. The following table presents one candidate star, which qualifies as Shatabhishaja based on brightness, location with reference to moon traverse band, and distance from previous Nakshatra.and 99 others whose identity has not been proposed -There is great dilemma about star for Shatabhishaja because one hundred stars of brightness <+5 brightness are not visible. Did one hundred bright objects exist in this part of sky 5000 years ago? One bright star near ecliptic is 90f Aqr, and best qualifies as single star identity of Shatabhishaja. The other identities are SAO-146595/SAO-146620, or HD-219449/HD219688. This star pair is 50 minutes or 13 degrees (E-W) away from Dhanishta, which is in ideal location.|
|Proshtapada||2||Purvabhadra||/ Guru||BhadrapadaSeptember-October||Kumbha, Meena||All the stars in this Meena Raashi are very low in brightness. Modern astronomers always use this area to identify new Sun’s minor planets because of less interference from low brightness stars.||If a single star is to be found to represent Poorvabhaadra, the best choice is SAO128513/HD224617 /28w Psc. Star Poorvabhaadra really is in Meena Raashi. The brightness is +4.02.|
|Proshtapada||2||Uttarabhadra||Ahirbadhni / Sani||Meena||If a single star is to be found to represent Uttara Bhaadra, then the best candidate is 63 dPsc, SAO-189474/HD-4656. It is in the moon band and is located about 12-14 degrees (E-W) away from Poorvabhaadra. But 71e is only 7 degrees away from Revati, while 63 is midway between Poorvabhaadra and Revati.|
|Revathi||32||Pausha / Budha||Balarama’s wife||Meena||If one star has to be identified for Revati, it is 99h Psc, which is the brightest star of Meena Raashi. Its identities are SAO-92484 or HD-9270.The brightness is +3.62. It is 45 minutes or about 12 degrees (E-W) away from Uttarabhaadra.|
- Graha means gravitational body not Planet.
- “The Grahas referred to in The Vedas are Surya, Chandra, Brihaspati, Shukra, Budha, Shani, Kuja, Rahu, Ketu.
- The Vedas extensively refer to Nakshatra month names and moon pointing at different Nakshatra‘s for various purposes.
- The European view (originally from Chaldian and Kassarian cultures of Middle East and from Egypt), propagated by Greek philosophers, of the night sky and the star system ran in a different direction in ancient times in that Sun was considered as the pointer to skies. In contrast, the moon is considered to be the primary pointer from vedic astronomical point of view.
C. Varas : Days of the week : were in use at the time of Janamejaya’s Rule. See Janamejaya’s Dana Sasana Patram They are still in use today.

|Brihaspativasara or Guruvar||Thursday||Jupiter|
|Bhargava vasara or Shukravar||Friday||Venus|
|Sthiravasara or Shanivar||Saturday||Saturn|
D. Rasis or Zodiac Signs :
It is likely that zodiac names travelled from India to Greece.
- Given the closeness in meaning of Rasi Names in Sanskrit and Greek. (This suggests interaction)
- Given the Date of the Bharata war and the Date of Sri Rama (These happened first)
- Why we have 30 days to a lunar month : The time between two successive full moons is 29.53059 solar days, which can be approximated to 30 solar days. The size of fractional moon exposure to sun can indicate a day count and is defined as a moon day or tithi. Thirty tithi‘s are defined in a lunar month, each tithi being smaller than a solar day. Fifteen are identified as Shukla paksha or ascending fortnight and next fifteen are called krishna paksha or descending fortnight.
- Why we use 27 nakshatras : The moon takes 27.32166 days to go around the earth. This is the sidereal month. It covers 1 nakshatram per solar day approximately. The moon functions as an astronomical day count clock in which Moon is the pointer and the stars are numerals in the sky pointed to by moon each day of the lunar month.
- The reason for time between full moons being higher than sidereal month is because, the moon has to go around the earth by more than a revolution (nearly 390 degrees) to keep with earth which moves forward in its trajectory around sun.
- How we got the names of the months: “The twelve months were named after the stars at which full moon occurs and these are Chaitra, Vaishakha, Jyeshta, Ashaada, Sharavna, Bhadrapda, Ashwija, Kaartika, Margashira, Pushya, Maagha, Phalguna.”
- Lunar Month : “Though the lunar time between two successive full moons is 29.53059 solar days, the time taken for moon to go round the earth (sidereal month) is 27.32166 days. Moon also has an oscillatory motion crossing the ecliptic. The moon anomalistic motion and nodal motion have periods are 27.55545 and 27.21222 days for a revolution around earth. The Chandramaana lunar calendar system keeps a natural cyclic count of days using both Moon based properties

F. Rtus (Seasons)
- What are the names of the Vedic seasons: The six-season definition is unique to vedic system and is not found in any other recorded culture or system. These seasons are, Vasanta, Geeshma, Varsha, Sharad, Himavanta and Shishira each season being about two moon cycles.
