Major-period lengths and the initial balance
In the standard 120-year Vimshottari sequence, Ketu receives 7 years. The birth lunar mansion determines the starting planet, and the proportion traversed within it determines the remaining balance of the first period. Life therefore often begins partway through a major period already underway.
Ketu's natal responsibilities, actual placement, condition and connections shape the specific themes of this period.
Period lord themes: detachment, discernment, and the limits of familiar experience
Ketu is the descending node, opposite Rahu. It often concerns detachment, discernment and dissatisfaction with established experience; specific themes depend on its life area, sign ruler and the chart as a whole.
Ketu often prompts a reassessment of familiar experience. A reading can explore which approaches have lost their appeal, how existing abilities can still be used, and what the next stage requires.
Ketu's house, sign ruler and same-sign relationships bring these themes into specific areas of life.
Ketu: life area and changes between stages
Ketu in angular or trinal houses, the 11th house, or supportive connections may give different results from Ketu in difficult or afflicted positions. Its life area, sign ruler and same-sign relationships show what these seven years chiefly affect.
These supportive and impairing conditions may occur together. The reading uses the actual chart to explain which is more prominent for the question at hand.
The order and proportions of the nine subperiods
Antardashas begin with the mahadasha planet itself and continue in the fixed nine-planet sequence. Each duration equals the mahadasha years multiplied by the antardasha planet's standard years, divided by 120. The table below shows three decimal places.
Exact Gregorian start and end dates are determined jointly by the birth instant, the balance of the first period, and the year length. This site uses a Saura year of 365.2422 days for conversion.
| Antardasha planet | Duration derived from the standard year proportions |
|---|---|
| Ketu | 0.408 |
| Venus | 1.167 |
| Sun | 0.350 |
| Moon | 0.583 |
| Mars | 0.408 |
| Rahu | 1.050 |
| Jupiter | 0.933 |
| Saturn | 1.108 |
| Mercury | 0.992 |
How major periods and subperiods work together
The major period provides the stage’s background; subperiods add conditions for results to form, persist or change. Combined with divisional charts for the relevant areas, they offer a more specific view of opportunities, burdens and progress during this time.
For example, if work someone once excelled at has lost its appeal, explore what has changed in their goals or environment and how their existing abilities can still be used.
