Cerridwen provides planetary data that focuses on our solar system and is suitable for both astronomical and astrological uses. This data includes sunrise times, phases of the moon, the tropical position of the sun, etc. Cerridwen's primary data sources are the Swiss Ephemeris library and its own algorithms, which calculate the phases, rising times, and setting times of the moon.
