Pick both dates to see zodiac compatibility.

How it works

First each date becomes a tropical Sun sign, then an element. The same element scores 92. Fire with Air or Earth with Water scores 84. Other pairs score 58 with a compromise label. 8 August 1988 (Leo, Fire) and 12 April 1992 (Aries, Fire) is 92.

1 January 2000 (Capricorn, Earth) and 7 July 1977 (Cancer, Water) is 84. Leo and 1 June 1990 (Gemini, Air) is also 84. 15 May 1990 (Taurus, Earth) and Leo is 58. 9 September 1999 (Virgo, Earth) and 3 March 1991 (Pisces, Water) is 84. Cancer and Sagittarius is 58.

A comparison of the elements of two Sun signs. We do not compute rising sign, Moon, Venus, or aspects. The band describes elements, not relationship quality. The same element does not guarantee harmony. A “harder” pair can still build a good bond.

Sign boundaries match the zodiac-sign card. A cusp day belongs to one band. Clock time does not enter.

Fields: date A and date B, YYYY-MM-DD. Click Calculate. One date and its element live on the zodiac-element page. A second pairing model lives on numerology compatibility.

Treat 92, 84, and 58 as combination labels. Do not read them as a verdict on a couple or dating advice.

Formula

signA / signB from date (tropical table) → elementA / elementB.

score: same element = 92; Fire↔Air or Earth↔Water = 84; otherwise = 58.
