Kalachakra Dasa is (like Vimsottari) a Lunar Nakshatra Dasa, i.e. a Dasa that is based upon the position of the Moon in her Lunar mansion.

But there are fundamental differences between Kalachakra and other Nakshatra Dasas

- Kalachakra is based upon Nakshatra
**Padas**(instead of Nakshatras). The reader may recognize that Nakshatra Padas are the same as Navamsas. That means that Kalachakra is a*Navamsa based Nakshatra Dasa*. - It is a Rasi Dasa (instead of Graha Dasa), i.e. the Dasa lords are Rasis and not planets.
- There are different opinions about the calculation methods. This is a problem similar to the Dasas of Jaimini Astrology.
- The Dasa is extremly sensitive for birth time and Ayanamsa changes. So it is applicable only if the native's birth time is quite accurate. A change of Ayanamsa can result in completely different results.

Each Nakshatra of the zodiac gets 9 different steps of the chakra. There are therefore 108 * 9 = 972 Dasas in the zodiac.

There are two main step directions of the chakra: direct and reverse
motion. The first is called *Savya*, the second is called *Apsavya*.

- The motion in Savya is from Aries to Pisces. It begins again in Aries after finishing one cycle of the zodiac.
- The Apsavya motion is similar but reverse. So it proceeds from Pisces to Aries, etc.

There are two different chakras in Savya and Apsavya. So we get in total 4 groups of chakras.

These groups are called

- 1a. Aswini group (first Savya group)
- 1b. Bharani group (second Savya group)
- 2a. Rohini group (first Apsavya group)
- 2b. Mrigasira group (second Apsavya group)

Savya and Apsavya Nakshatras build groups of three. First group (1a/2a) comes at the beginning and at the end of each cycle, i.e. the order is Aswini-Bharani-Aswini for Savya and Rohini-Mrigasira-Rohini for Apsavya.

The table below shows how to map Nakshatras to the 4 chakras.

Number | Nakshatra | Savya/Apsavya | Group |
---|---|---|---|

1 | Aswini | Savya | 1. Aswini |

2 | Bharani | Savya | 2. Bharani |

3 | Krittika | Savya | 1. Aswini |

4 | Rohini | Apsavya | 3. Rohini |

5 | Mrigasira | Apsavya | 4. Mrigasira |

6 | Ardra | Apsavya | 3. Rohini |

7 | Punarvasu | Savya | 1. Aswini |

8 | Pushyami | Savya | 2. Bharani |

9 | Aslesha | Savya | 1. Aswini |

10 | Magha | Apsavya | 3. Rohini |

11 | Purvaphalguni | Apsavya | 4. Mrigasira |

12 | Uttaraphalguni | Apsavya | 3. Rohini |

13 | Hasta | Savya | 1. Aswini |

14 | Chitra | Savya | 2. Bharani |

15 | Swati | Savya | 1. Aswini |

16 | Visakha | Apsavya | 3. Rohini |

17 | Anuradha | Apsavya | 4. Mrigasira |

18 | Jyeshta | Apsavya | 3. Rohini |

19 | Mula | Savya | 1. Aswini |

20 | Purvashadha | Savya | 2. Bharani |

21 | Uttarashadha | Savya | 1. Aswini |

22 | Sravana | Apsavya | 3. Rohini |

23 | Dhanista | Apsavya | 4. Mrigasira |

24 | Satabhisha | Apsavya | 3. Rohini |

25 | Purvabhadra | Savya | 1. Aswini |

26 | Uttarabhadra | Savya | 2. Bharani |

27 | Revati | Savya | 1. Aswini |

- There is a change of Savya/Apsavya after 3 Nakshatras = 12 Navamsas. So the odd cycles in Navamsa chart are Savya, the even ones are Apsavya.
- Savya and Apsavya change every 3 Nakshatras. But there is Savya at the beginning and at the end of the zodiac; so we can find 6 Savya nakshatras if we proceed from Purvabhadra to Krittika.

The following shows the results of the table above in reverse logical order, i.e. Nakshatras are shown in their groups.

Group | Subgroup | Nakshatras |
---|---|---|

Savya | 1. Aswini | Aswini, Krittika, Punarvasu, Aslesha, Hasta, Swati, Mula, Uttarashadha, Purvabhadra, Revati |

Savya | 2. Bharani | Bharani, Pushyami, Chitra, Purvashadha, Uttarabhadra |

Apsavya | 3. Rohini | Rohini, Ardra, Magha, Uttaraphalguni, Visakha, Jyeshta, Sravana, Satabhisha |

Apsavya | 4. Mrigasira | Mrigasira, Purvaphalguni, Anuradha, Dhanista |

Paramayus is the maximum span of one cycle of the Kalachakra. Paramayus means also maximum span of life. There are 4 types of Paramayus: 83, 86, 85 and 100 years. These values depend on the birth Nakshatra and the Pada.

The table shows the Paramayus for Savya/Apsavya chakra depending on the Nakshatra Pada of the birth chart.

Type/Years | 1st | 2nd | 3rd | 4th |
---|---|---|---|---|

Savya Chakra | 100 | 85 | 83 | 86 |

Apsavya Chakra | 86 | 83 | 85 | 100 |

Each Rasi has a fixed duration between 4 and 21 years. See table below.

Rasi | Lord | Years |

Aries, Scorpio | Mars | 7 |

Taurus, Libra | Venus | 16 |

Gemini, Virgo | Mercury | 9 |
