Venus Sign Calculator

Your Venus sign is the zodiac sign Venus occupied when you were born, and it is read as the part of a chart that governs love, attraction and taste. Where the Sun describes what you are becoming and the Moon what you need, Venus describes what you want: how you express affection, what draws you to a person, what you find beautiful, and what you treat as valuable. It is the placement people reach for when a Sun sign description of their relationships does not fit - which is often, because the two are not measuring the same thing.

Venus never strays far from the Sun in the sky - at most about forty-seven degrees - so your Venus sign is always your Sun sign or within two signs of it on either side, five possible signs in all. That constraint is why Venus sign and Sun sign so often coincide, and why the cases where they differ are informative. Venus moves a little over a degree a day when direct, spending three to five weeks in a sign, but it also turns retrograde for about forty days every nineteen months. During a retrograde it can cross back over a boundary it has already passed, which is why a table of date ranges cannot be trusted for Venus the way one roughly can for the Sun.

This is a free Venus sign calculator with no signup, and it asks for less than a full birth chart. Most people only need a birth date, since Venus stays in one of the twelve zodiac signs for weeks at a time. A birth time and city matter only when Venus changed sign on your birthday. Unlike a zodiac Venus sign calculator built on date tables, it is not thrown off by a retrograde year, and the result shows the sign, its exact degree, element, modality and ruler, plus the house when you give a time and place.

This calculator computes Venus's actual position rather than looking it up. It uses the VSOP87 planetary theory - the standard analytic model of the solar system, published by Bretagnon and Francou at the Bureau des Longitudes - reduced to the terms that matter at this precision, then corrects for light travel time and aberration to give the position as it appeared from Earth. The test suite checks the result against JPL Horizons, NASA's ephemeris service, to within six arcseconds at eight dates between 1905 and 2060.
