How common is this birthday
May 21 among the 366 days
May 21 averages 11,472 births a day in the US — the 143rd most common of the 366 dates, 1.1% above the average day. The deep dips are holidays.
Which sign, by birth year
- Gemini at midday UTC
- Taurus at midday UTC
- Sign changed during the day (UTC)
- 2026
Gemini at midday UTC in 72 years and Taurus in 28: 1930, 1931, 1933, 1934 … 1987, 1991, 1995. In 75 of the years — dotted — the Sun entered Gemini during May 21 itself, so a birth that day can be either sign depending on the hour.
- Gemini
- Taurus
- 2026
The bar is the whole of May 21 in UTC; where its color changes, the Sun crossed into Gemini, so a birth after that minute is Gemini. The time on the right is that minute.
- 9 of these 21 years had the change inside May 21 itself, so the hour of birth decides — from as early as 12:37 AM UTC in 2026 to as late as 8:45 AM in 2015.
- In 2016, 2017, 2020, 2021, 2024, 2025, 2028, 2029, 2030, 2032, 2033 and 2034 the whole day was already Gemini: the crossing came on May 20.
- Two sites can give two different signs for May 21 because both print a fixed range, and no fixed range is right in every year — the noon sign here flipped 33 times between 1930 and 2029.

May 21 opens Gemini in 2026: the Sun crossed in at 12:37 AM UTC on May 21, and the Jupiter decan that starts here lasts until May 31.
Jupiter widens the sign — more appetite, more optimism, and less patience with detail. In its first ten degrees Gemini shows in its rawest form: Taurus has only just handed over, and nothing of the new sign has worn down yet.

The Moon and nakshatra columns change every year because the Moon returns to the same calendar date in a different position — which is why a birth date alone cannot tell you those, and why this table exists.

The most frequent is 3 with 12 years; every other number, 11 included, turns up in 11 years. And this date can carry a master number: 11 in 11 of those years — kept whole rather than reduced. Why 11, 22 and 33 are treated differently →
Why the answer moves
There is no third sign and no blend — at your moment of birth the Sun was one side of the boundary or the other. For May 21 that came out Gemini in 72% of years and Taurus in 28%. The noon sign switched 33 times between 1930 and 2029; the last three switches fall in 1992, 1995 and 1996.
