Planetary Clock is a precise, beautifully simple planetary-hours clock. Since antiquity, each day and night has been divided into twelve unequal hours, each governed by one of the seven classical planets in the Chaldean order. Planetary Clock computes these hours with astronomical accuracy from the true sunrise and sunset in the city you choose. โข Current planetary hour โ see which planet rules right now, with a live countdown to the next hour. โข Ruler of the day โ the classical planet that governs today. โข Upcoming hours โ a clear timeline of the planetary hours ahead, from sunrise to sunset and through the night. โข Moon phase โ the current phase and illumination of the Moon. โข Monthly calendar โ lunar phases and planetary hours at a glance. โข 3D chart โ your birth chart rendered in three dimensions, with transits and aspects. โข Sync across devices โ sign in and your calendar and chart settings follow you. Planetary Clock is a subscription app. A monthly or annual plan unlocks everything, with a free trial when your Apple Account is eligible. No ads, and no tracking. Signing in with Apple or Google keeps your data in step across your devices. You pick your city by searching for it โ the app does not use GPS โ and every planetary hour is computed from that city's coordinates and time zone, so the same place is used on every device.
