Planetary positions for any date and time
-
High-precision and highly accurate planetary calculations. Tropical zodiac (for 2006, add 5 degrees 10 minutes then subtract a sign to convert to Sidereal). Note that if you add longitude and latitude (and, optionally, altitude) it will correct these for parallax, which can shift the Moon as much as a degree - for astrological purposes, you don't want this.

How can I find the current conversion to sidereal positions?

Most astrology programs make this conversion automatically when you calculate a Sidereal chart. The current Sidereal longitude of the vernal point (at the start of 2013) is 5°04' Pisces. Although you can convert current Tropical to Sidereal positions by subtracting 24°56' from everything (30°00' minus 5°04'), the faster (and more usual) way is to add 5°04' and subtract a whole sign.
This VP position moves 5' of arc for every 6 years of time. It increases as you move to the past, and decreases moving into the future. Thus, for early 1963 (50 years ago), subtract one-sixth (1/6 of 50', in round numbers, is 8'): the amount travelled is 50' - 8' = 42'. Add that to the current value (5°04' Pisces) to get 5°46' Pisces for early 1963.
A short table of VP values for current times is given in the front of Andromeda Sidereal Ephemeris of the 21st Century which you can download for free from https://www.thelema.org/publications#article--monographs
