How long it lasts
The Saturn mahadasha lasts 19 years. Antardasha = 19×18/120 = 342/120 = 2.850000 years, i.e. about 2 years, 10 months, 6 days.
Here 1 year = 365.25 days.
The order of the antardashas
The Saturn mahadasha opens with Saturn's own antardasha (BPHS ch. 51: the first antardasha belongs to the dasha lord), then the planets follow in Vimshottari order: Saturn → Mercury → Ketu → Venus → Sun → Moon → Mars → Rahu → Jupiter. The Rahu antardasha is the eighth in this sequence and begins 13 years, 7 months, 12 days after the mahadasha starts.
What tradition holds
Tradition links the Saturn mahadasha with discipline, patience and long effort, and reads the Rahu antardasha as adding a note of unfamiliar paths, ambition and change. Patience meets change, and a slow, regular pace is seen as most useful. It is a period tradition reads as asking for patience and routine; the real picture comes from where both planets sit in the chart.
