The Observatory

An astronomical event calendar, moon phase engine, and living night-sky map with Greek myth and symbolic starlore sprinkled in.

Approximation note: This sky calendar uses astronomical formulas for educational and exploratory use. Dates and positions are approximate, especially far in the future. For mission-critical observing, verify with professional ephemeris tools. Astrology-inspired content is cultural and symbolic.
