UAC 2026

The American Federation of Astrologers (AFA) invites you to join us the day before UAC begins for our ORG Day event from 9 am to 5 pm: The Pain in the Math class!

This class will cover all the math that the student will need to know to cast an astrological chart.

This entails the following:

• Calculating Local Mean Time at birth, Sidereal Time at birth, and Greenwich Mean Time at birth
• Calculating planetary longitude using two different techniques, one using fractions and another using logarithms
• Calculating declinations, Part of Fortune, and house cusps
• Calculating the ACD, progressing a chart to a specific date, including progressed Asc. and MC.
• (If time permits, we will cover how to calculate applying and separating aspects, the last and next aspect the moon will make, the largest and smallest orbs.
