Antardasha 6 of 9 in Mars mahadasha · 4 mo 27 d
Mars-Ketu antardasha मंगल-केतु अंतर्दशा
Mars-Ketu lasts about four months and twenty-seven days. Ketu is conventionally treated as Mars-like, so this pairs two similar forces, and tradition reads it as intense and abrupt. Sudden decisions, accidents, surgery, and disputes are classical themes, along with a strange loss of interest in fights that seemed important. Research, occult study, and technical breakthroughs are the constructive side. Short, sharp, and often remembered long afterward.

The mahadasha behind it
Mars mahadasha is a seven year period that tradition associates with energy, courage, competition, property, and siblings. After the receptive Moon period it feels abrupt and active, with a strong pull toward decisive action. Classical texts read a strong Mars as bringing achievement through effort and gains in land or technical fields, while a weak or afflicted Mars brings disputes, accidents, and conflict with brothers or authority.

What Ketu adds as sub-lord
Ketu mahadasha is a seven year period that tradition associates with detachment, sudden turns, and a loosening of attachments to things that no longer serve. It usually opens quietly after the busy Mercury period and asks for inward focus rather than expansion. Classical texts read it as a time of spiritual gain and material uncertainty, with results depending heavily on the house and sign Ketu occupies. As an antardasha lord it colours the mahadasha's agenda rather than replacing it: the houses Ketu owns and occupies in the birth chart become the stage for Mars's themes for 4 mo 27 d. See Ketu as a mahadasha.
How the length is computed
Mars runs 7 years and Ketu runs 7 years in the 120-year cycle, so Mars-Ketu lasts 7 × 7 ÷ 120 = 0.408 years, about 4 mo 27 d. The exact calendar boundaries depend on the Moon's degree at birth; the free kundli lists them.
