1 Day for 1 Year". This is the phrase generally used in reference to the way which astrological progressions are computed. It is the basis for the calculation of a progression according to the procedure employed by us

One of the many astrological topics which needs clarification and a more revealing and significant approach is what is usually called "progressions"

There are many ways that astrologers "progress" a chart. One of the most popular techniques is called "Secondary Progressions". With this system, astrologers equate one day after birth to one year of life (the day-for-a-year method).

Secondary Progressions furnish the best starting point for finding the current trend in life through the close aspects that have formed between the natal and progressed planets. This technique employs the assumption that one day of planetary transits is equal to a year of life.

The Moon moves around the earth in an orbital cycle and in doing so reflects the light of the sun in an ever-changing relationship. At the same time, the earth is orbiting the sun and our view from earth of this orbit is the apparent path of the sun across the Ecliptic.

If you look at any date in the Ephemeris, you will notice that the Moon travels at a much greater speed in a day than do the planets.
