Mercury Retrograde Calendar 2018 November and December

Mercury rules Gemini and Sagittarius is its Shadow, so this retrograde will be interesting. It suggests the revelation of international missteps. Because Sagittarius rules the courts, past misdeeds and missrepresentations may surface. In 2017, the December retrograde in Sagittarius presented a clash between the US, NATO and the United Nations.

Using the 2018 Mercury Retrograde Calendar

The calendar shows the three phases and four significant points of each Mercury Retrograde Cycle. Mercury appears retrograde when it is on the far side of the Sun from our perspective on the earth. Its motion is direct when it is on the near side relative to the earth.

The Pre-Shadow

The Pre-Shadow is the phase when mercury passes over the part of the sky that it will later be retrograde. Often this phase sets up the errors, false assumptions and omissions that are revealed during the retrograde itself. It is shown in blue. As Mercury slows down towards the retrograde, the effect is strengthened, and this is shown in violet.

The Retrograde

The Pre-Shadow ends with the Mercury Retrograde Station, as Mercury appears to hang in the sky, as it is about to go backwards and behind the Sun. It is during the retrograde phase that the areas that Mercury rules tend to bring up challenges, especially in communication, scheduling and detailing. This phase is shown in pink. During the beginning and end of this phase, Mercury is moving more slowly and the effect is stronger. This is shown in a darker color.

The Post-Shadow

For the next two weeks or so, Mercury enters the Post-Shadow as it moves in front of the sun and over the part of the sky it had been previously retrograde, Typically, the Post-Shadow reveals the errors, false assumptions and omissions that may have occurred previously, especially during the earlier phases of the cycle. This phase is shown in brown with the days Mercury is still  moving slowly emphasized with a darker  color.

Mercury Retrograde is Really About Not Being Centered

At its core, the experiences of mercury retrograde are the consequences of actions that occur when we are disconnected from our core and center. It is then that we act from our tunnel vision, from assumptions without checking or being aware.

Although we can not do much for the actions of others, we can certainly do our own part for ourselves. If you seek to do this I recommend  a book that illumines the practical path to do just that:
