How long it lasts
The Ketu mahadasha lasts 7 years. Antardasha = 7×16/120 = 112/120 = 0.933333 years, i.e. about 11 months, 6 days.
Here 1 year = 365.25 days.
The order of the antardashas
The Ketu mahadasha opens with Ketu's own antardasha (BPHS ch. 51: the first antardasha belongs to the dasha lord), then the planets follow in Vimshottari order: Ketu → Venus → Sun → Moon → Mars → Rahu → Jupiter → Saturn → Mercury. The Jupiter antardasha is the seventh in this sequence and begins 3 years, 11 months, 18 days after the mahadasha starts.
What tradition holds
Tradition links the Ketu mahadasha with turning inward, simplicity and the spiritual, and reads the Jupiter antardasha as adding a note of knowledge, guidance and dharma. Wisdom meets the spiritual, linked with inner understanding and practice. The real picture comes from the signs and houses of both planets in the chart.
