Declination in Astrology
Declination is every planet’s angular distance north or south of the celestial equator. Unlike longitude, it is a physical sky coordinate, independent of zodiac framing and house system. The three guides below cover out-of-bounds planets, parallel and contraparallel aspects, and the 18.6-year lunar standstill cycle. The five calculators and five OOB date references apply the same ideas to any chart or date range.
Guides
- Out-of-Bounds Planets
What it means when a planet passes the Sun's ±23°26' envelope, which bodies can and cannot do it, and how OOB reads natally versus in transit.
- Parallel and Contraparallel Aspects
Declination-axis conjunctions (parallels) and oppositions (contraparallels). Why they matter even when the zodiacal aspect is absent.
- Lunar Standstills and the 18.6-Year Cycle
How the precession of the lunar nodes drives the Moon's declination envelope between major (±28.7°) and minor (±18.3°) amplitudes.
