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 Budha’s 17 years — not opinion.
| Sub-period | Duration | What it colours |
|---|---|---|
| Budha–Budhamercury | 2y 4m 27d | Intellect, speech and commerce. |
| Budha–Ketuketu | 0y 11m 27d | Detachment, endings and the inward pull. |
| Budha–Śukravenus | 2y 10m 0d | Relationships, comfort and the arts. |
| Budha–Sūryasun | 0y 10m 6d | Authority, the ego and the father-principle. |
| Budha–Candramoon | 1y 5m 0d | The emotional mind, mother and inner tides. |
| Budha–Maṅgalamars | 0y 11m 27d | Drive, courage and open conflict. |
| Budha–Rāhurahu | 2y 6m 18d | Ambition and the unorthodox. |
| Budha–Gurujupiter | 2y 3m 6d | Wisdom, dharma and expansion. |
| Budha–Śanisaturn | 2y 8m 9d | Discipline, delay and endurance. |
| Full mahādaśā | 17y 0m 0d | Nine sub-periods, one lord. |
Method: antardaśā = (sub-lord’s Vimśottarī years × 17) ÷ 120, on the 360-day classical convention. Anchored to your Moon’s nakṣatra, these become exact calendar dates.
02What the 17 years structure
A clean Mercury makes these seventeen years sharp and productive — study, business, communication, skill. Entangled with malefics, the mind scatters, speech misfires, and commerce turns nervous. Budha takes the colour of its associations.
None of this predicts events. It is the classical tendency of a placement — a lens for timing, not a verdict.

How long is Budha Mahādaśā?
17 years — its Vimśottarī allotment. It divides into nine antardaśā sub-periods, from Budha–Budha (2y 4m 27d) to Budha–Śani (2y 8m 9d).
Is Budha Mahādaśā good or bad?
Neither by default. It depends on Budha’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 Budha 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 Budha 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.
