## 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 Guru's 16 years — not opinion.

Guru Mahādaśā · antardaśā timeline
| Sub-period | Duration | What it colours |
| ---------- | -------- | --------------- |
| Guru–Gurujupiter | 2y 1m 18d | Wisdom, dharma and expansion. |
| Guru–Śanisaturn | 2y 6m 12d | Discipline, delay and endurance. |
| Guru–Budhamercury | 2y 3m 6d | Intellect, speech and commerce. |
| Guru–Ketuketu | 0y 11m 6d | Detachment, endings and the inward pull. |
| Guru–Śukravenus | 2y 8m 0d | Relationships, comfort and the arts. |
| Guru–Sūryasun | 0y 9m 18d | Authority, the ego and the father-principle. |
| Guru–Candramoon | 1y 4m 0d | The emotional mind, mother and inner tides. |
| Guru–Maṅgalamars | 0y 11m 6d | Drive, courage and open conflict. |
| Guru–Rāhurahu | 2y 4m 24d | Ambition and the unorthodox. |
| Full mahādaśā | 16y 0m 0d | Nine sub-periods, one lord. |
Method: antardaśā = **(sub-lord's Vimśottarī years × 16) ÷ 120**, on the 360-day classical convention. Anchored to your Moon's nakṣatra, these become exact calendar dates.

## 02What the 16 years structure
A dignified Jupiter delivers the most expansive years of a life — wisdom, mentors, children, faith, growth of every kind. Even afflicted, Guru rarely destroys; it merely narrows the abundance. This is the daśā most charts hope to be living.

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 Guru Mahādaśā?16 years — its Vimśottarī allotment. It divides into nine antardaśā sub-periods, from Guru–Guru (2y 1m 18d) to Guru–Rāhu (2y 4m 24d).

Is Guru Mahādaśā good or bad?Neither by default. It depends on Guru'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 Guru 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 Guru 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.
