## 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.

Budha Mahādaśā · antardaśā timeline
| 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.

## 03Common questions
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.
