Rahu is the north node — hunger without a body, ambition without limit. Its eighteen years amplify desire and the unconventional, and can raise a chart to sudden heights or into fog, by placement.
01The nine antardaśās, computed
Every mahādaśā divides into nine sub-periods in the fixed Vimśottarī order, beginning with the daśā lord itself. Their lengths are a fixed proportion of Rāhu’s 18 years — not opinion.
| Sub-period | Duration | What it colours |
|---|---|---|
| Rāhu–Rāhurahu | 2y 8m 12d | Ambition and the unorthodox. |
| Rāhu–Gurujupiter | 2y 4m 24d | Wisdom, dharma and expansion. |
| Rāhu–Śanisaturn | 2y 10m 6d | Discipline, delay and endurance. |
| Rāhu–Budhamercury | 2y 6m 18d | Intellect, speech and commerce. |
| Rāhu–Ketuketu | 1y 0m 18d | Detachment, endings and the inward pull. |
| Rāhu–Śukravenus | 3y 0m 0d | Relationships, comfort and the arts. |
| Rāhu–Sūryasun | 0y 10m 24d | Authority, the ego and the father-principle. |
| Rāhu–Candramoon | 1y 6m 0d | The emotional mind, mother and inner tides. |
| Rāhu–Maṅgalamars | 1y 0m 18d | Drive, courage and open conflict. |
| Full mahādaśā | 18y 0m 0d | Nine sub-periods, one lord. |
Method: antardaśā = (sub-lord’s Vimśottarī years × 18) ÷ 120, on the 360-day classical convention. Anchored to your Moon’s nakṣatra, these become exact calendar dates.
02What the 18 years structure
Rahu magnifies whatever it touches. Well-channelled, its eighteen years bring worldly rise, foreign gains and unconventional success. Poorly placed, they bring confusion, obsession and reversals that arrive without warning. Rāhu is amplitude, not judgement.
None of this predicts events. It is the classical tendency of a placement — a lens for timing, not a verdict.

How long is Rāhu Mahādaśā?
18 years — its Vimśottarī allotment. It divides into nine antardaśā sub-periods, from Rāhu–Rāhu (2y 8m 12d) to Rāhu–Maṅgala (1y 0m 18d).
Is Rahu Mahādaśā good or bad?
Neither by default. It depends on Rāhu’s house, sign and dignity in your chart — a well-placed graha gives its best significations, an afflicted one strains them. Classical texts describe a tendency, never a fixed fate.
Which antardaśā matters most?
The sub-period whose lord is strong and friendly to Rāhu usually reads best; one that is afflicted or inimical is felt hardest. A computed reading of your own chart resolves it precisely.
How do I find my own Rāhu Mahādaśā dates?
Exact dates need your birth date, time and place, because the sequence is anchored to your Moon’s nakṣatra at birth. Karma Jyotiṣa computes it free.
