Astrology is also about recurring cycles that aid or hinder at different times. Mercury retrograde is one such cycle that recurs three times each year. Since the planet Mercury is related to all forms of communication, written and oral, this is not the time to sign important documents, legal agreements, or to initiate something new. You can, however, review and renew things already under way. Once Mercury is direct, go ahead and launch your project.
Mercury also rules travel and the mechanism to get you there. It's not unusual to have mechanical problems during this cycle. Expect breakdowns and/or
mix-ups with travel arrangements as well.
In 2007 Mercury is Retrograde on the following dates:
February 14 - March 8
June 15 - July 10
October 12 - November 2
The closest orbiting body to earth is the Moon and her influence is so important that two branches of astrology, Electional and Horary, use the Moon as primary significator.
The Moon moves very quickly and in her travels makes many aspects to the planets in the sky. When she is not in aspect, or ceases to make an aspect she is referred to as Void-of-course. These void time intervals may occur for a few minutes or hours on any given day. When the Moon is void "nothing of consequence will evolve" and its best to delay important activities.
