How long it lasts

The Mercury mahadasha lasts 17 years. Antardasha = 17×19/120 = 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 Mercury mahadasha opens with Mercury's own antardasha (BPHS ch. 51: the first antardasha belongs to the dasha lord), then the planets follow in Vimshottari order: Mercury → Ketu → Venus → Sun → Moon → Mars → Rahu → Jupiter → Saturn. The Saturn antardasha is the ninth in this sequence and begins 14 years, 3 months, 21 days after the mahadasha starts.

What tradition holds

Tradition links the Mercury mahadasha with learning, communication and practical skill, and reads the Saturn antardasha as adding a note of discipline, patience and long effort. 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.
