May 20 Zodiac Sign: Taurus or Gemini? Exact Times

Am I Taurus or Gemini?

This is the actual question, and almost every page that comes up for it prints an approximate date range and leaves you no better off. Here is the real answer. The Sun does not change sign at midnight, or on the same date every year. The Earth's year is 365.2422 days rather than 365, so the changeover drifts about six hours later each year and jumps back when a leap day is inserted. Over a century that moves it across two or three calendar dates.

On May 20 specifically, the Sun was in Gemini rather than Taurus in 8 of the 106 years surveyed: 2004, 2008, 2012, 2016, 2020, 2024, 2028 and 2032.

Born before that time on that date, you are the earlier sign. Born after it, you are the later one. Those times are US Eastern: if you were born elsewhere, convert. Three hours earlier on the west coast, five hours later in London, and so on.

Where the Sun actually sits on May 20

Not just the sign: the degree. Each sign is thirty degrees wide and the Sun covers roughly one a day, so a birthday pins it to about a degree. On May 20 the Sun falls between 28.7 and 30.0 degrees of Taurus, the variation coming from the same leap-year drift.

The third decan of Taurus

Decans are a much older idea than Sun signs and a more specific one. Each sign divides into three ten-degree stretches, each with its own planetary ruler drawn from the Chaldean order, so a Taurus born in the third decan is not quite the same as one born in the others. May 20 falls in the third, ruled by Saturn.

In practice that means the Taurus traits run through a Saturn filter rather than only through Venus. The same system assigns a tarot card to every decan: this one is Seven of Pentacles, which is a genuinely useful second description of the same ten degrees and one almost nobody connects back to a birthday.

What a Taurus born on May 20 is like

The honest version first. A birthday gives you the Sun, and the Sun is one of about ten things in a chart. It describes what you are consciously trying to become rather than how you behave on a Tuesday, which is usually the Moon and the rising sign. Everything born on May 20 in a given year shares this Sun, so nothing on this page is personal to you.

With that said: Taurus is Earth and Fixed, ruled by Venus, and the traits most often attached to it are steady, sensual, patient, stubborn and loyal. Its recognised weak spot is that it digs in long after the ground has moved. The third decan adds Saturn, which tends to sharpen that picture rather than soften it.

What your birthday cannot tell you

The three things people most want from astrology, which are their rising sign, their Moon sign and their houses, all need a birth time and a birth place as well as a date. The Moon moves about half a degree an hour, so it can change sign inside a single day. The rising sign changes completely every two hours. A date on its own gets you the Sun and very little else.

If you do not know your birth time, this covers how to get it, including which record to ask your state for and which one leaves the hour off.

Your solar return is not always on your birthday

This surprises people and it follows directly from everything above. A solar return is the moment the Sun comes back to the exact degree it held when you were born, and a year of that cycle is 365.2422 days rather than 365. So the moment drifts about six hours later each year and snaps back on a leap year, which means it regularly falls on the day before or the day after May 20.

In practice: if you were born late on May 20, your solar return will often land on May 21 in some years. If you were born early in the day, it will sometimes fall on the 19th. It is not a mistake in the calculation; it is the same quarter-day that moves the sign boundaries.

That matters if you use the technique, because a solar return chart is cast for that exact moment and for wherever you happen to be standing. How to read one is here.

The date opposite May 20

Every point in the zodiac has one directly across from it, and so does every birthday. For May 20 that is November 21, when the Sun sits at roughly the same degree of Scorpio, the opposite sign.

The gap between them is 185 days rather than a tidy half of 365, because the Earth moves faster through its orbit in early January, when it is closest to the Sun, than in early July when it is furthest. The two halves of the year are genuinely different lengths, by about seven days.

Astrologically the opposite date is the other end of your axis: Taurus and Scorpio want different things and the tradition treats them as two halves of one problem rather than as enemies. Taurus and Scorpio compatibility is covered here.
