Find house cusp ingresses for Sun or Moon

Overview

Detect when the Moon or Sun crosses house cusps at a given location. House cusps are location- and time-dependent — they rotate with the Earth, completing a full rotation roughly once per sidereal day (~23.93 hours). Both the Moon and Sun cross all 12 cusps approximately once per day. **Range limits:** 7 days for Moon, 90 days for Sun.
