How long it lasts
The Mars mahadasha lasts 7 years. Antardasha = 7×6/120 = 42/120 = 0.350000 years, i.e. about 4 months, 6 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 Sun antardasha is the eighth in this sequence and begins 6 years, 24 days after the mahadasha starts.
What tradition holds
Tradition links the Mars mahadasha with courage, effort and initiative, and reads the Sun antardasha as adding a note of self-confidence, responsibility and self-respect. This meeting of energy and leadership is linked with considered initiative. The real picture comes from the signs and houses of both planets in the chart.
