Venus Square Pluto...

starts on October 15 (using a 1 degree orb), is exact on October 16 at 4.21am and leaves on the same day.  Venus at 0 degrees and 58 minutes of Libra, Pluto at 0 degrees and 58 minutes of Capricorn.

This is a bit of a baptism of fire for Venus as she tries to settle into Libra, a sign that she likes.  However, although a stressful day or so, this period of time represents the opportunity to reach a turning point with the relationships and themes represented by Venus and Pluto in your birth chart.  Look to see where this aspect is happening, and also to which houses are ruled by Venus (Taurus and Libra), and Pluto (Scorpio).

The square is a stressful aspect and one that suggests that you are likely to reach a stage where something has to change in regards to the areas represented in your own chart.  This stress gives the incentive for us all to actually do something about whatever is causing the stress.

If you have personal planets and/or points in the early degrees of any of the cardinal signs (Aries, Cancer, Libra and/or Capricorn) you are likely to feel this aspect especially strongly.
