How long it lasts

The Mars mahadasha lasts 7 years. Antardasha = 7×17/120 = 119/120 = 0.991667 years, i.e. about 11 months, 27 days.

Here 1 year = 365.25 days.

The order of the antardashas

The Mars mahadasha opens with Mars's own antardasha (BPHS ch. 51: the first antardasha belongs to the dasha lord), then the planets follow in Vimshottari order: Mars → Rahu → Jupiter → Saturn → Mercury → Ketu → Venus → Sun → Moon. The Mercury antardasha is the fifth in this sequence and begins 3 years, 6 months after the mahadasha starts.

What tradition holds

Tradition links the Mars mahadasha with courage, effort and initiative, and reads the Mercury antardasha as adding a note of learning, communication and practical skill. Action meets intellect: effort guided by a plan. The real picture comes from the signs and houses of both planets in the chart.
