What is it?
For entertainment purposes only. Western astrology divides the year into 12 zodiac signs, each ~30 days long, beginning with Aries at the spring equinox (~March 21). Each sign belongs to one of four elements (Fire: Aries, Leo, Sagittarius; Earth: Taurus, Virgo, Capricorn; Air: Gemini, Libra, Aquarius; Water: Cancer, Scorpio, Pisces) and one of three modalities (Cardinal: initiators; Fixed: sustainers; Mutable: adapters). This calculator uses a simplified approximation � cusp dates (around the 20th�23rd of each month) may be off by one sign.
How to use
Enter your birth month (1�12) and day. The calculator returns an approximate sun sign index (0=Aries through 11=Pisces), along with element and modality indices. Because the 30-day approximation is simplified, people born on cusp dates should verify with a precise ephemeris or an astrology site.
Example scenario
Born July 1: dayOfYear = 1 + (7-1)�30 = 181. sunSignIndex = floor(181/30.4) = 5 ? Virgo (index 5). Element = 5 mod 4 = 1 ? Earth. Modality = 5 mod 3 = 2 ? Mutable. Virgo is indeed an Earth-Mutable sign � analytical, detail-oriented, and adaptable according to astrological tradition.
Pro tip
The elements in Western astrology loosely map to personality archetypes: Fire signs (Aries, Leo, Sagittarius) are associated with energy and action; Earth signs (Taurus, Virgo, Capricorn) with practicality and stability; Air signs (Gemini, Libra, Aquarius) with intellect and communication; Water signs (Cancer, Scorpio, Pisces) with emotion and intuition. These archetypes appear in Jungian psychology and many storytelling frameworks, making them interesting cultural and literary references regardless of one's beliefs in astrology.
