Without accurate birth time, an astrologer’s forecast for the client could be off by a year, or more, which is not professionally acceptable. This 5-week course focuses on time range searches from a few minutes to six hours and meets the PAA/NCGR rectification requirement for their Level IV professional certification.

Even with a birth certificate, all birth times should be tested because of the wide disparity of recording around the world. Testing ensures that the ANGLES of the chart are confirmed by movement techniques that show the activation of the natal chart at dates of major life events. If they don't, the astrologer and client can determine if rectification of the birth time is needed and what is to be accomplished by the search. To rectify the chart, the client often needs to be asked for additional information about specific life turning points based on his or her memory, records, family, and/or friends. 

Common problems with recorded birth time accuracy are:

  1. Times rounded to the quarter-hour,
  2. Times recorded in standard time by statute, when daylight time was in effect,
  3. Clock and watch variances, and
  4. Birth time is not a priority for the medical staff.

By the end of this course, students will be able to apply various chart movement techniques to align appropriate chart patterns and astrological significators to actual life events, from a few minutes of known birth time to a 6-hour search. They will learn the important areas of practice and controversy in rectification; demonstrate knowledge of timing techniques; evaluate activated natal chart angles at important events, and derive a time that can consistently be repeated and aligned with major events.

Weekly Topics Include:

  • Problematic Issues: Assessing the Need for Birth Time Rectification
  • How to Assess the Natal Chart Dynamics to Set the Stage for Rectification
  • If the Birth Time Doesn’t Match Events, Why Does It Matter? Looking at first-tier techniques.
  • Arcing Planets to Angles Can Confirm Birth Time
  • Putting Rectification Theory into Practice

This course does require a good knowledge of transits, progressions, directions and other methods of moving the chart in time. 

Advanced astrology software that can search various movement methods is highly recommended, such as: Solar Fire 9, Sirius 3.0, Time Passages, and others. Jigsaw (a research program) is not required.

Gloria SciglianoInstructor Gloria Scigliano, has a BS Information Systems, San Francisco State University. Gloria's interest in astrology began in the early 1970s, after a difficult time led her to an astrologer for a five-minute-five-dollar reading. During the years of raising her children, Gloria worked in the software development field, eventually traveling all over the US and Canada teaching large corporations how to install and implement the company's financial software. There was little time for astrology, and there were so many laborious steps involved! Untold hours were spent dreaming of better designs for astrology systems. When Solar Fire came along, readings for family, friends, and then clients finally got serious.


After moving to Alaska in 1988, she began writing an astrology column for a local paper in Pacifica, California which, in turn, led to creation of her website at www.stellardays.com. And finally, she found the online Diploma of Professional Astrology program offered by Kepler College, which she completed in 2015. However, for Gloria, astrology seems to be a life-long learning adventure. The search is still on for discovering the Karmic path hidden in the natal charts, developing her Horary skills, and sensing the energies of the planets as they impel and compel us through life.
