Mars antardasha in Jupiter mahadasha
Mars antardasha in Jupiter mahadasha lasts 11 months and begins about 12 years 8 months in (sub-period 8 of 9). See the exact Vimshottari math, the classical Jupiter–Mars relationship, and how to check it against your own chart.
Direct answer
In the 16-year Jupiter mahadasha, the Mars antardasha lasts 11 months (16 × 7 ÷ 120 years) and arrives as sub-period 8 of 9, starting about 12 years 8 months in. By the BPHS natural-friendship table, Mars is a natural friend of Jupiter, so the two lords' agendas tend to cooperate — though chart-specific lordships can override this. What it actually delivers depends on the houses Mars and Jupiter own and occupy in your chart — which is why we check the period against your real past first.

Why this page won't tell you your future
Two people in the same Mars-in-Jupiter period can live opposite stories, because what each planet delivers is set by the houses it rules and occupies in the individual chart — not by the combination alone. The honest way to read this period is to compute your chart, see what Jupiter and Mars actually control for you, and verify the pattern against dated events from your own past before trusting forward-looking claims.
