The date table it uses

Only the month and day matter - there is no year field, because the twelve Western sun signs are matched against a fixed calendar table:

Sign	Dates	Element
Aries, Leo, Sagittarius	21 Mar-19 Apr, 23 Jul-22 Aug, 22 Nov-21 Dec	Fire
Taurus, Virgo, Capricorn	20 Apr-20 May, 23 Aug-22 Sep, 22 Dec-19 Jan	Earth
Gemini, Libra, Aquarius	21 May-20 Jun, 23 Sep-22 Oct, 20 Jan-18 Feb	Air
Cancer, Scorpio, Pisces	21 Jun-22 Jul, 23 Oct-21 Nov, 19 Feb-20 Mar	Water

15 June therefore returns Gemini, an Air sign. Capricorn is the one span that crosses New Year, so it is matched as two pieces - late December and the first nineteen days of January.

Cusp dates and what the table cannot know

The real boundary is the moment the sun crosses into the next sign, and that instant moves by up to a day from year to year. Aries begins at the March equinox, which in 2026 is 20 March rather than the 21st in the table. If your birthday is the first or last day of a sign, the answer here can differ from a chart drawn for your exact birth time and place.

Any day from 1 to 31 is accepted for any month, so 31 February will return Pisces without complaining. Check the date is real first. This is the tropical zodiac used in Western astrology; Vedic astrology uses sidereal positions and will usually give the previous sign.

Frequently asked questions

What zodiac sign is 15 June?

Gemini, which runs 21 May to 20 June. A day later, 21 June, and it is Cancer.

What does my element mean?

The twelve signs are grouped into Fire, Earth, Air and Water, repeating in that order around the circle, so signs of the same element sit 120 degrees apart - four groups of three.

What is a cusp birthday?

A birthday on the first or last day of a sign's range. Because the sun's crossing shifts each year, only a chart cast for your birth time settles which side of the line you fall on.
