Hi X..........Welcome to the forum,
Think of the original chart as showing how you are programmed to behave, in order to attract the events needed to achieve psychological growth over the course of your lifetime............the progressed chart as a year-by-year indication of where/how you should be growing.......and transit charts as pointing to the events you are likely to attract.
The progressed chart is calculated on the basis that "one day after birth = 1 year of life"........so, your progressed chart for age 1 is drawn using same birthtime and location but on 27th March 1989.......and that for age 20 on 15th April 1989 at 14.58 in Taunton, MA.........[Note
: The chart you've drawn is a " daily progressed chart" for 22nd June 2009........To draw the "day-for-a-year progressed chart" at astro.com, you have to amend the chart start date to 26th March 2009 rather than use the already filled-in default date....which was 22nd June 2009 when you drew the progressed chart].
We then compare the Natal and progressed charts to determine any significant changes, as these reveal the areas where opportunities for growth will occur in the next year/progressed chart period.........And, we also look at the progressed chart as a "stand-alone" chart for further information.
However (if you are a "greenhorn") you'll need to first get a thorough understanding of your natal chart before attempting to make sense of any progressions to it.
