This New Moon in Sagittarius occurs Sunday, December 5 at 12:37 pm EST (5:37pm GMT). New Moons are a time of new beginnings and undertaking new projects; since this New Moon occurs in Sagittarius, these projects will likely center on adventure, discovery, and personal experiences, whether they be physical (by planning future travels, say) or mental (through learning or new personal understanding). This is likely to be a weekend of fun and discovery, no matter your definitions.
Uranus is now direct after five months in retrograde, which could add new dimensions of your knowledge and insight of your own self. All other planets are also currently direct until December 10 (when Mercury again goes retrograde–eek!).
Mars is also in Sagittarius, which will add an air of determination to any new undertakings (or adventures) that you may begin.
