Calculations

Calculate transits at one requested instant

Requested-instant transit-to-natal aspects. Not an event search, aspect windows, station prediction or house-transit report. Engine output remains nested under transits.

Each admitted request reserves one monthly usage unit before route validation or engine work; failed or timed-out admitted attempts are not refunded. Do not automatically retry. Historical mode uses an explicit BCE/CE date object and UT1 conventions. Its response is the versioned historical envelope, not the modern UTC envelope. Read result for calculation fields and metadata for limits and uncertainty.
