| Role | Degrees in Cancer | Nakshatra | Width |
|---|---|---|---|
| Star lord | 16°40′00″ – 30°00′00″ | Ashlesha | 13.33° |
| Sub-lord | 5°26′40″ – 7°20′00″ | Pushya (Saturn) | 1.89° · ≈8 min of Ascendant motion |
| Sub-lord | 16°40′00″ – 18°33′20″ | Ashlesha (Mercury) | 1.89° · ≈8 min of Ascendant motion |
The narrowest Mercury sub-lord slice in Cancer is 1.89° wide, about 8 minutes of Ascendant motion; the widest is 1.89° (≈8 min). The Ascendant moves roughly 1° per 4 minutes on average, so a few minutes of birth-time error can change the sub-lord.
