A diagram of celestial positions and local chart angles for a particular time and place.

Why it matters

A birth chart brings several pieces of information into one diagram: zodiac positions, chart angles, houses and aspects for a particular time and place.

Example

Two people born on the same date can share a Sun sign but have different Ascendants and house placements if they were born at different times or locations.

Common confusion

The astronomical positions used to construct a chart can be calculated. The meanings astrologers assign to those positions are interpretations, not scientifically established effects.
