The International Astrology Day, annually celebrated by astrologers and enthusiasts on March 20 or 21 (sometimes March 19), is held on the day of the vernal equinox. This day of a unique natural phenomenon begins a new astrological year.
More than ten years ago, Western astrologers suggested celebrating this holiday on March 20, the first day of the astrological year, when the sun enters Aries. It is interesting that in the Northern hemisphere the Day of the spring equinox is celebrated, while in the Southern - the Day of the autumn equinox.
