Astrological birth signs are not applicable only to your birth date.  Every year when the Sun transits each constellation (geocentric perspective), the characteristics of the birth sign are highlighted.  In the case of the Sun in Libra we are called to reflect on relationships and harmony in everything surrounding us.  The Sun enters Libra when the Autumn / Spring Equinox takes place.  During this event, both day light and night time reach a perfect balance.  The message in the stars is actually all around us: find harmony and balance between opposites.  Libra speaks of balance and harmony between the opposites and reminds us that one cannot exist without the other.  The transition in the seasons from summer to autumn and from winter to spring are again a manifestation of balance and a reminder that we could not survive without both cold and warm, day and night. 

Libra tends to be associated with relationships in terms of our partner or spouse, however it speaks about our relationship with the rest of the world, the way we relate to others and how do we find balance between our ego and the external world.  During the month of Libra (September 23 to October 22) the message for everyone is to find balance and to become aware of the need to find peace within ourselves in order to promote peace beyond our individual space.  Only in the extend we learn to relate with our individuality we are able to relate to others.
