About International Astrology Day
The vernal equinox is recognized as International Astrology Day because it marks the first day of the astrological year. The Earth spends its first full day in the astrological sign of Aries on the spring equinox.
International Astrology Day was first asserted by the Association for Astrological Networking in 1993 and is an annual observance/holiday celebrated by astrologers and astrology enthusiasts.
