The Sun’s rhythm in your location, divided among seven traditional planets.

Your reading

How the reading works

The planetary day starts at sunrise. Daylight is divided into twelve equal parts and night into another twelve, following the Chaldean order. Lengths vary with date and latitude. Historical time zones and clock changes apply, assuming a clear sea-level horizon. Without sunrise or sunset, no schedule is invented. Correspondences are symbolic.

Symbolic meaning; the calculation does not establish personal traits or predict events.

What this tool helps you explore

Explore day and night periods associated with the seven traditional celestial bodies. Look up their correspondences and place an activity within a location's solar rhythm.

How to use it

Choose a date and city, calculate and browse daytime and nighttime intervals. Read each period's ruler and interpretation. Check the displayed time zone, especially when looking up a different city.

Reading your result

A planetary hour need not last sixty minutes: daylight and darkness are divided separately. Associations are symbolic, not schedules that guarantee results. If sunrise or sunset is absent, the tool explains why a conventional table cannot be provided.
