How long it lasts
The Venus mahadasha lasts 20 years. Antardasha = 20×17/120 = 340/120 = 2.833333 years, i.e. about 2 years, 10 months.
Here 1 year = 365.25 days.
The order of the antardashas
The Venus mahadasha opens with Venus's own antardasha (BPHS ch. 51: the first antardasha belongs to the dasha lord), then the planets follow in Vimshottari order: Venus → Sun → Moon → Mars → Rahu → Jupiter → Saturn → Mercury → Ketu. The Mercury antardasha is the eighth in this sequence and begins 16 years after the mahadasha starts.
What tradition holds
Tradition links the Venus mahadasha with relationships, the arts and comfort, and reads the Mercury antardasha as adding a note of learning, communication and practical skill. Intellect meets art: skill, conversation and creativity. The real picture comes from the signs and houses of both planets in the chart.
