Horoscopic astrology is a form of astrology that relies on horoscopes, a pseudoscience suggesting that the alignment of the planets to the stars can be used to gain divination on someone's personality, answer questions they may have, or provide analysis on world affairs.

Natal astrology, also known as genethliacal astrology, is the most common type of horoscopic astrology where astrologers construct a horoscope for a person's date, time, and location of birth, and this is used to determine what their personality and path in life is. The first part is easy to understand as attention is paid to their sun sign, moon sign, and ascending (rising) sign. However, most people stop at their sun sign.

The second part is chart weighing by sign and house. Chart weighing by sign categorizes the signs in three categories: element (fire, earth, air, water),¹⁾ quality (cardinal, fixed, mutable),²⁾ and the polarity (positive, negative).³⁾ Meanwhile, chart weighing by house looks at the house modals the planets are in which could be angular (1st, 4th, 7th, 10th), succedent (2nd, 5th, 8th, 11th), and cadent (3rd, 6th, 9th, 12th).⁴⁾

Lastly, we have chart shaping which generally analyzes any patterns that the planets are in, and also checks if most of the planets fall under a specific hemisphere (northern, southern, eastern, western).⁸⁾

Interrogatory astrology, also known as horary astrology, is a branch of horoscopic astrology where the astrologer tries to answer a question by constructing a horoscope for the time and location it was asked. It relies on moon position and the question being assigned to one of the twelve houses. Naturally, this branch is best suited for vague questions and, while the answer may be simple, it can also provide some options.

Babylonian astrology, also known as mundane astrology or political astrology, is the oldest branch of astrology that uses horoscopes to analyze world affairs and events, usually the weather and politics. Most historians believe it emerged within the second or third millennium before the common era, with other forms of horoscopic astrology being invented and popularized around the sixth century before the common era.

A horoscope is a chart or diagram that maps out where the planets and stars are in relation to Earth at a given date, time, and location. They're typically generated for someone's birth for natal astrology, but can also be generated for other situations as explained in the previous sections.

Western astrology divides the chart into twelve houses and their division relies on a bunch of factors that are way too convoluted to summarize within a short paragraph. Each house represents an aspect of life that play a significantly huge role in regards to interrogatory astrology.

• There have been discussions of a potential 13th zodiac sign between Scorpio and Sagittarius named “Ophiuchus” (⛎) but it boils down to astrologers explaining that constellations and signs aren't the same thing despite their naming schemes, and astronomers being irritated that astronomy is still being mistaken for astrology. The “re-calculated zodiac” story is from September 2016 and was debunked.
