How long it lasts

The Saturn mahadasha lasts 19 years. Antardasha = 19×17/120 = 323/120 = 2.691667 years, i.e. about 2 years, 8 months, 9 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 Mercury antardasha is the second in this sequence and begins 3 years, 3 days after the mahadasha starts.

What tradition holds

Tradition links the Saturn mahadasha with discipline, patience and long effort, and reads the Mercury antardasha as adding a note of learning, communication and practical skill. Intellect meets discipline, linked with orderly work and deep study. The real picture comes from the signs and houses of both planets in the chart.
