How to Read Your Dasha, Step by Step

A Vimshottari dasha timeline is built from one number: the Moon’s sidereal longitude at birth. Everything below follows from it by division, and the steps are worked on one example, a birth on 1 January 2000 at 06:00 IST, computed by the same code the dasha calculator runs. The example is only an illustration of the arithmetic.

1. Find the Moon’s nakshatra: it names the first period

The nine lords run in a fixed order, Ketu 7, Venus 20, Sun 6, Moon 10, Mars 7, Rahu 18, Jupiter 16, Saturn 19, Mercury 17, 120 years in all, and the same order assigns the nakshatras their lords. In the example the Moon is in Swati, pada 3, whose lord is Rahu, so the life opens in the Rahu mahadasha.

2. Work out the balance: how much of it is left

The first mahadasha is not given in full. The Moon had already covered 52.7% of Swati, so the same share of Rahu’s 18 years is treated as already spent, and 8 years 6 months remain. That balance is the most sensitive figure in the whole timeline: a birth time a few minutes out moves the Moon, the balance, and every date after it.

3. Lay out the sequence

After the balance, each lord follows in order with its full length. The calculator counts in solar years of 365.2425 days; the texts state the same proportions in years of 360 days, so two programs’ dates can differ by weeks late in a long period.

4. Open a mahadasha into its nine sub-periods

Each mahadasha divides among the same nine lords, starting from its own. In the example the third mahadasha is Saturn’s, from 8 July 2024; its antardashas begin on 8 July 2024 (Saturn), 12 July 2027 (Mercury), 21 March 2030 (Ketu), and so on to Saturn–Jupiter from 26 December 2040. The length of any sub-period, and of the nine pratyantars inside it, is on its own page: for example Saturn–Mercury.

5. Read the lords against the chart, not against a list

A timeline says which lords are running; it does not say what they will do. In Parashari practice a period is read through the houses its lords rule and occupy in the birth chart, which depends on the ascendant. The houses each mahadasha lord and its sub-period lords rule are worked out for every ascendant on pages like the Saturn mahadasha for Aries ascendant; where they actually sit needs the chart itself. A page or a person that tells you what a period will bring without having looked at both is describing the system, not your life.

For the system as a whole, see Vimshottari dasha explained, and for all 81 sub-periods with their lengths, the antardasha table. Reading the rest of the chart is covered in how to read your kundli. In Hindi: अपनी दशा कैसे पढ़ें.
