How long it lasts

The Rahu mahadasha lasts 18 years. Antardasha = 18×7/120 = 126/120 = 1.050000 years, i.e. about 1 year, 18 days.

Here 1 year = 365.25 days.

The order of the antardashas

The Rahu mahadasha opens with Rahu's own antardasha (BPHS ch. 51: the first antardasha belongs to the dasha lord), then the planets follow in Vimshottari order: Rahu → Jupiter → Saturn → Mercury → Ketu → Venus → Sun → Moon → Mars. The Mars antardasha is the ninth in this sequence and begins 16 years, 11 months, 12 days after the mahadasha starts.

What tradition holds

Tradition links the Rahu mahadasha with unfamiliar paths, ambition and change, and reads the Mars antardasha as adding a note of courage, effort and initiative. Energy meets new paths, and tradition advises pausing before decisions. It is a period tradition reads as asking for patience and routine; the real picture comes from where both planets sit in the chart.
