Secondary progressions
Progressions relate symbolic time to a birth chart. They do not simply show the real sky’s positions on the consultation date.
How it is defined
Secondary progressions commonly use one day after birth for one year of life. Other techniques apply different rules.
How to read it
A useful reading explains its rule before proposing questions. Keep the compared data distinct from the meaning a particular school assigns to it.
A concrete example
For year 30, the day-year rule uses approximately the thirtieth day after birth. This is not the real sky on the thirtieth birthday or a guarantee of change.

Before extending a reading, identify the data the technique requires and what the application actually provides. Keep the rule with your notes so comparisons use consistent criteria.
