May 21 is a changeover day. At noon UTC across the 41 years from 1992 to 2032, the Sun was in Gemini in 40 years and Taurus in 1 year.
The Sun moved from Taurus into Gemini on May 21 in 21 of those years. The latest time in this span is 21 May 2031 at 05:27 UTC. That minute shifts from year to year, and a birth city changes which clock time it falls on.
Gemini usually runs May 21 to June 20. It is an air sign, ruled by Mercury. Taurus is the sign just before it. Curious, talkative, always juggling ideas.
The constellation behind the Sun on May 21 is Taurus. That is the true place of the Sun in the stars, and it is a separate fact from the astrological sign.
