Cazimi Calculator

Cazimi is the condition of a planet being in the very heart of the Sun, and in classical astrology it counts as one of the strongest states a planet can reach. But there is a widespread misunderstanding: not every conjunction with the Sun is a cazimi.

A real cazimi requires two conditions at once. It is not enough for the planet to share the Sun’s longitude; it must also align in declination, that is, genuinely pass in front of the Sun’s disc. That condition is usually not met. A planet can reach the same degree as the Sun while passing well above or below the disc; in that case what you have is not cazimi but the deepest point of combustion.

Cazimi is also possible only for Mercury and Venus, because by the geometry of the sky only these two planets can pass in front of the Sun’s disc.

Scans forward from today and shows the first real cazimi it finds. Real cazimis are rare, so the scan may take a few seconds.

A combust planet rises with the Sun and sets with the Sun, and is never visible in the night sky; by the classical rule a planet that cannot be seen cannot rule. Cazimi is the opposite: it is the planet’s most hidden yet most powerful moment.

Calculations use the astronomy-engine ephemeris and have been cross-checked against a Swiss Ephemeris reference implementation. The cazimi criterion follows the classical 17-arcminute declination condition. Times are Turkey time (UTC+3); Turkey has not observed daylight saving since 2016.
