    Function getProgressedAnglesTimeBased

    • Calculate progressed angles using time-based method.

      Parameters

      • birthJD: number

        Julian Date of birth

      • targetJD: number

        Julian Date to progress to

      • latitude: number

        Birth latitude

      • longitude: number

        Birth longitude

      • progressionType: ProgressionType = 'secondary'

        Type of progression for date calculation

      • houseSystem: HouseSystem = 'placidus'

        House system

      Returns ProgressedAngles

      Progressed angles

      Time-based method calculates angles for the actual progressed moment:

      • Get the progressed Julian Date
      • Calculate angles for that date/time at birth location
      • This gives angles that account for precession and time passage

      This method is more astronomically accurate but less commonly used in astrological practice.
