Direct answer
In the 17-year Mercury mahadasha, the Jupiter antardasha lasts 2 years 3 months (17 × 16 ÷ 120 years) and arrives as sub-period 8 of 9, starting about 12 years 1 month in. By the BPHS natural-friendship table, Jupiter is neutral toward Mercury — the period's tone depends almost entirely on what each planet controls in your chart. What it actually delivers depends on the houses Jupiter and Mercury 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 Jupiter-in-Mercury 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 Mercury and Jupiter actually control for you, and verify the pattern against dated events from your own past before trusting forward-looking claims.
