Natal and tertiary progressions INatal chart with tertiary progressions I in the outer circle. With additional tables (PDF). In the method Tertiary I, each day after the day of birth is equivalent to one lunar month in an individual's life. Key for progressions in Tertiary I: 1 day in the ephemeris = 27.32158218 days in life. The Tertiary Progression I (also called tertiary direction I) is based on the idea that there is a symbolic analogy of 1 month = 1 day, a "month" referring to the so-called tropical month of 27.32158 days. So, the age of a person is calculated in tropical months and a chart is generated for the same number of days after birth. Unlike the progressed chart, the tertiary chart does not change continuously, but remains identical for a whole month in a person's life, i.e. it changes after the chosen month in a person's life is completed.
