A set of Tables of Houses for Lat
Definition
“A set of Tables of Houses for Lat” refers to a set of astrological house tables prepared for a particular terrestrial latitude, with “Lat” functioning as an abbreviation for latitude. Before astrology software, astrologers used such printed tables to convert local sidereal time into house-cusp positions for a chosen house system. Separate tables were needed because the relationship between the ecliptic and the local horizon changes with geographic latitude.
Astrological Meaning
Tables of Houses are calculation tools rather than interpretive symbols. They help establish the degree placed on each house cusp, including the Ascendant and Midheaven, for a specific time and location. Those cusps divide a horoscope into areas associated with topics such as identity, resources, relationships, vocation, and community. The resulting positions can vary according to latitude and the house system used, so the table must match the astrologer’s chosen method.
Why It Matters
Accurate house tables were essential to traditional chart construction and remain useful for understanding how horoscopes are calculated. Choosing a table for the wrong latitude can shift house cusps and may alter which houses contain particular planets, affecting interpretation. Studying these tables also clarifies that house placement depends on birth time, location, and calculation method—not only on zodiacal position. Modern software usually performs this work automatically, but the underlying geographical and astronomical principles still matter when checking a natal chart or comparing house systems.
