What Is Kalachakra Dasa

Share this post

Most people who have had their horoscope read know the Vimshottari dasa: Sun 6 years, Moon 10, Mars 7 and so on. Fewer know that Parashara also described a second, very different timing system, the Kalachakra dasa ("wheel of time" dasa). Classical writers praised it highly, and serious astrologers still use it to confirm the timing they see in Vimshottari.

This guide explains how Kalachakra dasa works, step by step, without heavy mathematics.

Planet periods and sign periods

In Vimshottari, each period belongs to a planet. In Kalachakra, each period belongs to a sign (rasi). The years a sign receives depend on its lord:

Sign	Lord	Years
Aries	Mars	7
Taurus	Venus	16
Gemini	Mercury	9
Cancer	Moon	21
Leo	Sun	5
Virgo	Mercury	9
Libra	Venus	16
Scorpio	Mars	7
Sagittarius	Jupiter	10
Capricorn	Saturn	4
Aquarius	Saturn	4
Pisces	Jupiter	10

Rahu and Ketu have no periods in this system, because they own no sign.

Step 1: the Moon's nakshatra and pada

Everything starts from the Moon at birth. The zodiac has 27 nakshatras, each divided into four padas of 3 degrees 20 minutes. Kalachakra looks at both the nakshatra and the pada, so two people born in the same star can run completely different Kalachakra sequences.

Step 2: Savya or Apasavya

The 27 stars fall into two families:

Savya (clockwise): Ashwini, Bharani, Krittika, Punarvasu, Pushya, Ashlesha, Hasta, Chitra, Swati, Moola, Purvashada, Uttarashada, Purva Bhadrapada, Uttara Bhadrapada and Revati (15 stars).
Apasavya (anti-clockwise): Rohini, Mrigashira, Ardra, Magha, Purva Phalguni, Uttara Phalguni, Vishakha, Anuradha, Jyeshtha, Shravana, Dhanishta and Shatabhisha (12 stars).

In Savya stars the signs are counted forward; in Apasavya stars the order is reversed. Each family is further split into two groups (Savya I and II, Apasavya I and II), which decides where each pada's sequence begins.

Step 3: the pada's nine signs

Every pada owns a fixed run of nine signs, and the lengths of those nine signs add up to the pada's full cycle:

Pada	Savya cycle	Apasavya cycle
1st	100 years	86 years
2nd	85 years	83 years
3rd	83 years	85 years
4th	86 years	100 years

For example, the first pada of Ashwini (a Savya I star) runs Aries, Taurus, Gemini, Cancer, Leo, Virgo, Libra, Scorpio and Sagittarius: 7 + 16 + 9 + 21 + 5 + 9 + 16 + 7 + 10 = 100 years.

The sequences are not always a simple forward count. After Pisces, the Savya order jumps and runs through Scorpio, Libra, Virgo, Cancer, Leo, Gemini, Taurus, Aries and back from Pisces. These jumps (called gatis, "movements") are one of the features that make Kalachakra distinctive. Classical texts describe them as the leap of a frog (Manduka gati), the look of a lion (Simhavalokana) and the backward turn of a monkey (Markati gati). Astrologers watch the dasa that begins with such a jump, because it often coincides with a sudden change of direction in life.

Step 4: the dasa running at birth

The Moon is rarely at the very start of its pada. How far it has already moved through the pada tells us how much of the pada's cycle had already passed before birth.

Suppose a pada has a 100-year cycle and the Moon has covered a quarter of the pada. Then 25 years of the cycle had passed at birth. Counting the sign periods from the start (7, then 16...), the first sign has finished after 7 years and the second after 23, so the child is born in the third sign's dasa, with 2 years of it already gone. What remains of it is the dasa balance at birth. From there, the following signs run one after another.

Kalachakra uses a 360-day year, as many classical dasa systems do, so its dates drift slightly from a solar calendar. Good software handles this for you.

Step 5: bhuktis and antharams

Each dasa is divided into nine bhuktis (sub-periods) that follow the same nine-sign pattern, each in proportion to its own years. Each bhukti divides again into nine antharams. This gives the same fine timing astrologers are used to from Vimshottari.

Deha and Jeeva

Each pada's sequence has two special signs:

Deha (body): for Savya stars, the first sign of the sequence.
Jeeva (life): for Savya stars, the last sign of the sequence.

For Apasavya stars many texts reverse the pair, so check which convention your astrologer follows.

Traditional texts read the planets in these two signs, and the periods of these signs, with extra care. Benefics in the Deha and Jeeva signs are taken as supportive for the body and the life force. Afflictions there call for more caution in their dasa, which means care with health and routine rather than fear.

How astrologers use Kalachakra dasa

As confirmation. If Vimshottari shows a marriage or career change in a certain year and the Kalachakra period of the 7th or 10th house sign also runs then, the astrologer's confidence rises.
For sign-based reading. Because each period is a sign, the reading looks at the house that sign occupies from the Lagna, the planets inside it and its lord's strength. The dasa of the sign holding the 10th house, for example, tends to bring career matters forward.
At the gatis. A jump in the sequence is read as a turning point.

You can compare this with the house-based career reading in our guide to career path and public reputation from the 10th house.

Why accuracy matters

Kalachakra is very sensitive to the Moon's exact position. A few minutes of arc can move the Moon into the next pada and change the whole sequence. So an accurate birth time, a correct ayanamsa and a reliable ephemeris matter even more here than for Vimshottari. Sithars Astrology works out the Moon's longitude with the Swiss Ephemeris and the Lahiri ayanamsa before any dasa is calculated.

A balanced view

Kalachakra dasa is a respected classical system, but it is best used alongside Vimshottari and the transits, not as a stand-alone verdict. If both systems point the same way, the timing is stronger; if they disagree, the astrologer looks at the chart as a whole. As with every dasa, a "difficult" period means a time to act carefully, not a fixed misfortune.
