Times are universal time — convert your birth time before reading your year.

Tradition prints May 21 as Gemini’s opening day, and sometimes the sky agrees — in about one year out of four, the Sun is already in Gemini when the date begins. In most years, though, the crossing happens somewhere inside May 21 itself, at whatever hour the ephemeris pleases, leaving the early part of the day to Taurus and the rest to the Twins. Check the table above: a sign means the whole day was one thing; a time means your birth hour decides.

Twins with topsoil

Whichever side of the line, May 21 people describe a similar mix: Gemini’s appetite for input planted in Taurus soil. The Gemini Sun’s curiosity is present — the questions, the tabs, the talking to strangers — but it moves at a walkable tempo and prefers its ideas to end up as objects. Call it the difference between wind and weather vane: this birthday registers every current while staying bolted to the roof. The Taurus Sun contribution is exactly that bolt.

Conversation you can build on

In love the blend is disarming: chatty warmth that actually follows through. This date courts by talking — then shows up Saturday with the tools, which is not a combination partners forget. Work sits happily where language meets material: explaining products, documenting a craft, negotiating over real goods, teaching hands-on subjects. Pure abstraction bores the earth half; pure repetition suffocates the air half.

When the halves trade vices

The friction shows up as vice-swapping: Taurus stubbornness defending Gemini whims — a fleeting interest suddenly held like a fortress — or Gemini restlessness undermining Taurus commitments right at the boring-but-crucial middle. The growth edge is matching the tool to the task: hold hard to the things chosen on purpose, stay light about the ones that drifted in. Sorting which is which takes about one honest evening.

Two signs, one date, and an answer that exists: the table above for your year, and — for split years — the birth chart calculator for your exact minute, which settles the Sun and maps the Moon, rising sign, and houses in the same pass.

The date, answered

What zodiac sign is May 21?

Taurus or Gemini — this date sits on the boundary. In 0 of the years from 1940 to 2030 the whole day belonged to Taurus; in 24 it belonged to Gemini; in 67 the Sun crossed over during the day. The year table above gives your answer, and a birth chart settles it to the minute.

What time does the sign change on May 21?

In years when the ingress lands on May 21, it falls between 00:05 and 23:02 universal time. In the other years the whole day is one sign. Convert your birth time to UTC before reading the table.

Which sign should I read?

Check your birth year in the table. If your year is a split year, the deciding fact is your birth time converted to universal time — or skip the table and compute your chart, which reads the Sun's exact degree for your birth moment.

What degree is the Sun on May 21?

Between 29°33′ Taurus and 0°57′ Gemini at noon universal time, depending on the year — the calendar drifts about a quarter degree per year against the Sun and resets on leap years. Your exact degree needs your birth date, year, and time.

The date gives you the Sun. The rest takes a chart.
