The order of the antardashas
The Jupiter mahadasha opens with Jupiter's own antardasha (BPHS ch. 51: the first antardasha belongs to the dasha lord), then the planets follow in Vimshottari order: Jupiter → Saturn → Mercury → Ketu → Venus → Sun → Moon → Mars → Rahu. The Mars antardasha is the eighth in this sequence and begins 12 years, 8 months after the mahadasha starts.
What tradition holds
Tradition links the Jupiter mahadasha with knowledge, guidance and dharma, and reads the Mars antardasha as adding a note of courage, effort and initiative. Courage meets wisdom, linked with energy put in the right direction. The real picture comes from the signs and houses of both planets in the chart.
