The service
Moon & Star Map is a tool provided by Zovo for use inside ChatGPT and other MCP clients. Moon & Star Map answers "what was the moon on my birthday?" with the exact phase, illumination and moon age computed from astronomical algorithms (Jean Meeus), checks whether two moons "complete each other", shows a moon-phase calendar for any month, and draws the sky above a city at a chosen date and time: about 2,900 stars from the Yale Bright Star Catalog, constellation lines, the horizon, the cardinal points and the Moon in its real position. Posters download as vector PDF (12x18 in, 18x24 in, A3, Letter, A4, with 0.125 in bleed) and SVG.
