In short: The Rahu antardasha within the Ketu mahadasha lasts 1 year 18 days (about 1.05 years). The Ketu mahadasha is an inward, detaching period. Within it, Rahu's sub-period tends to bring ambition, foreign links and sudden change. The two nodes in sequence; a turning point between detachment and new ambition.

How the two lords relate
A node is involved, so the relationship is read through the node's dispositor and conjunctions rather than BPHS's friendship table.
Classical practice also looks at where the two lords sit relative to each other in the birth chart:
| Position of the antardasha lord from the mahadasha lord | Traditional reading |
|---|---|
| together (same sign) | the two lords act jointly; results depend on their combined dignity |
| 2/12 from each other | classically a less comfortable relationship, often linked with expense or effort |
| 3/11 from each other | a supportive relationship of effort and gains |
| 4/10 from each other | angular to each other: a strong, active combination |
| 5/9 from each other | trinal to each other: the most harmonious relationship |
| 6/8 from each other | the classic difficult relationship (shadashtaka), linked with obstacles or strain |
| opposite each other (1/7) | in mutual aspect: a strong, sometimes polarised combination |
What changes the results
The antardasha delivers what Rahu promises in the chart, coloured by Ketu. Its results depend most on the houses Rahu rules and occupies for the ascendant, its dignity, and its relationship to Ketu. A well-placed antardasha lord in a supportive position from the mahadasha lord tends to give a constructive period; a weak or 6/8-placed one asks for patience. Transits of Jupiter and Saturn during the period, and the pratyantardashas (sub-sub-periods) within it, refine the timing further.
