Transit chart calculator
Enter your birth data and a transit moment (defaults to now). The calculator computes current planet positions, their placements in natal houses, and aspects from transit planets to natal Sun, Moon, planets, Ascendant, and MC. All computation runs in your browser.
What this calculator does
A transit chart overlays the present sky onto a natal chart. The transit planet positions are computed for the chosen moment; their sign and house placements are evaluated against the natal house cusps (Whole-Sign in this implementation).
Cross-aspects use major and minor classical orbs. Each aspect is labelled applying (transit planet moving toward exact) or separating(moving away), based on the planet's apparent ecliptic motion at the transit moment.
See birth chart for natal-only computation, current sky for transit positions alone, and methodology for the computational details.
Reference, not advice
This is cultural and astronomical reference, not personal prediction or advice.
Transit-to-natal aspects are geometric relations between sky positions at two moments. They are not personal forecasts. See disclaimer.
