hello I was wondering if someone could assist me . I am trying to locate a programme that will allow me to do synodic cycle calculations , maybe something like solar fire or similar . as an example this is what I am trying to do . let's say on a certain date Helio Mars and Saturn have an angular distance of 72 degrees . what I am trying to do is to progress just those two planets to the date where they will be square or 90 degrees at 162 degrees of seperation and then 120 degrees when they will be at 12 degrees seperation and so on to 360 degrees where they will be 72 degrees thanks
