Just a little discussion about the first day of Libra= Also called The Autumn (or Autumnal) Equinox
Here's the piccie of the other Equinox's and Solstices which are our seasons:
Spring-Aries, Summer-Cancer, Autumn-Libra, Winter-Capricorn.
The other Pagan Festivals are when the Sun is (approx) halfway through the Fixed signs of Aquarius-Imbolc, Taurus-Beltane, Leo-Lammas and Scorpio-Samhain
These are the lovely diaries that I use, aren't they fab!
