A Review Of ‘Diurnal’ Chart Advance

Discussion Invitation-J

In recent posts I have presented charts which some may find confusing in terms of how a Return chart relates to an Advanced charts and how that chart can be ‘turned’ forward or backwards within a given day to portray an ‘Event’ chart.  It is important for astrologers not familiar with these methods to feel comfortable with them.  In the big picture, all that is happening is that the natal chart (using the Sun’s precise position) is used to find the Moon’s exact time-of-day (for a future date) when the Moon contacts the natal Sun position.  This establishes a Moon-to-Sun Return chart and the initiation of its cycle.  We then follow that cycle forward each day using a ‘diurnal’ factors (the Sun’s daily rate of advance).  Once we have an Advanced chart for an event-date, we can rotate that chart within that day’s time frame to the time of the event.  In this case involving Carol Parrish, the event was in the morning hours.  The diagram below will be used to discuss this further.

Diurnal diagram-J

We can start with the area of the diagram marked “A.”  The black sine-wave is the plot of the Sun’s progress through the sky during its annual cycle, starting at the Aries point (spring) and continuing through the summer, fall, winter and back to the spring Aries point.  Each of us was born when the Sun was at some precise point along this black curve.  That point is important to us, individually, as it is a key factor symbolizing our identity, character, and attitude towards life.

This example point of birth is shown by the black circle.  Once each 28-to-29 days, the Moon will contact this precise zodiac point.  The red Lunar Cycle  indicates this through the following little circles (the Sun’s position) when the Moon’s orbital path crosses that point 12 or 13 times each year.  For my practice of Moon-to-Sun Returns I use a half-cycle (Moon-to-Sun and Moon-opposite-Sun).  The first person that wrote about these Moon-to-Sun Returns, Therese Sweeney in 1981, used a complete Lunar cycle.  You can see that I have indicated both the Lunar half-cycle and full-cycle in the diagram.

Let us now focus on area “B” in this diagram.  The red lunar cycle has been expanded to better-illustrate that the Return point (Moon-to-Sun) can be extended along the red sine-wave plot of the Moon’s movement through the zodiac as it advances over the course of its monthly cycle.  This daily advance occurs at the same time each day and reflects the Sun’s rate of advance through the sky.  This is called ‘Diurnal” or ‘daily’ motion.  Keeping the chart’s calculated time constant permits us to tie the Moon’s cycle to the Sun’s cycle, and that to our birth cycle. 

Still viewing section B of the diagram, keeping the same calculation time found in the Return chart, but changing or advancing the date used to calculate the chart, let’s put the chart in motion.  The chart angles advance a degree or so each day, the transiting planets take up slightly different positions — except that the fast-moving Moon may be found 12 or 13 degrees further along, the Sun may be a degree-or-so further along, etc. 

This charting method allows us to watch life unfolding, flowing along on a day-by-day basis as if it was a motion picture.  As long as we understand the context of the subject’s life, and the way in which they express their symbols, we can easily forecast the changes that will be faced and the conditions under which they will be encountered.  No other method of astrological charting does this so well, so simply.

Let us now move to area “C” of the diagram.  Once we are looking at an event date using the Advanced chart, we recognize that this is a cyclic view of what taking place on that date.  This ‘cyclic view’ reflects what the day’s changing nature is and how it is perceived by the subject.  However, it is not the event itself.  Merely how the event affects the flow of daily life.

To review the event, we need to rotate the chart forward or backward over the course of that day so that the chart’s calculated time reflects the time of the event.  In this case we have moved Carol Parrish’s Advanced chart time from late afternoon backward to 7:20 AM in the morning.  This method is what I term the ‘Double Diurnal’ method as it requires two adjustments of time from the Return chart to the daily chart to the event chart.

I hope this clarifies the idea behind how these charts are calculated.  Dave.

About dadsnook

Dave has been exploring cyclic astrology since the mid-1970's. CYCLIC astrology utilizes both Return charts and planetary-pair cycles for short-term prediction. These practices and four years of archived material are available for study or reading at ninthhouse.wordpress.com A new book, Personal Prediction ISBN 978-9-615-63033-5, has been published and the MC-Solar Cycle technique is now supported through a recognized software provider so that all students and practicing astrologers can apply these techniques for their own use. Recently, Dave has been exploring a new charting format:, transiting Moon to natal Sun Return charts. These moon-sun returns show how see seek to maintain or deal with change in our lives. A book is expected to be released in 2015. Contact Dave for details at dadsnook@charter.net Dave is a retired business systems analyst and automation systems engineer, enjoys woodcarving and tarot in addition to astrology.
