What the Stars Agree On Today

Your zodiac sign — also called your sun sign — is determined by the position of the Sun on the day you were born. The Sun moves through each of the twelve signs over the course of a year, spending roughly a month in each. For example, if you were born between 21 March and 19 April, your sign is Aries. If your birthday falls on a changeover day, the exact time and place of birth can confirm which sign the Sun was in. Use the birth calculator on Orveluna to find your sign instantly.

Western astrology recognises twelve signs: Aries (21 Mar – 19 Apr), Taurus (20 Apr – 20 May), Gemini (21 May – 20 Jun), Cancer (21 Jun – 22 Jul), Leo (23 Jul – 22 Aug), Virgo (23 Aug – 22 Sep), Libra (23 Sep – 22 Oct), Scorpio (23 Oct – 21 Nov), Sagittarius (22 Nov – 21 Dec), Capricorn (22 Dec – 19 Jan), Aquarius (20 Jan – 18 Feb), and Pisces (19 Feb – 20 Mar). The exact changeover date shifts slightly each year because the Sun does not move into a new sign at the same moment every year. Explore each sign in detail on the zodiac signs guide.

In Western astrology the twelve signs are grouped into four elements: Fire (Aries, Leo, Sagittarius), Earth (Taurus, Virgo, Capricorn), Air (Gemini, Libra, Aquarius), and Water (Cancer, Scorpio, Pisces). Each element is associated symbolically with a style of energy and perception — Fire with action and drive, Earth with practicality, Air with communication and ideas, and Water with emotion and intuition. This is an interpretive framework, not a scientific claim about personality. Read more on the Orveluna blog.

Ophiuchus is sometimes called a "thirteenth sign" because the Sun passes through the constellation between late November and early December, but Western astrology uses a fixed twelve-sign system based on the solar calendar, not on constellation boundaries. Within the standard twelve signs, Capricorn and Aquarius are statistically among the least common birth signs in many countries because their seasons fall during periods with lower birth rates. However, no sign is astronomically "rare" — the Sun spends roughly equal time in each. Browse all twelve signs on the zodiac signs page.

Your sun sign is determined by the Sun's position on your birth date and is the sign most people know. Your moon sign is the zodiac sign the Moon occupied at the moment of your birth; in astrological tradition it is associated with your inner emotional life. Your rising sign — also called the ascendant — is the sign that was rising on the eastern horizon at the exact time and place of your birth; it changes roughly every two hours, so knowing your birth time is essential. Together these three are sometimes called the "big three" in a birth chart. Learn more on the Orveluna methodology page.

Astrological compatibility between sun signs is an interpretive starting point within the Western tradition. Astrologers typically look at the relationship between elements (Fire, Earth, Air, Water), modalities (Cardinal, Fixed, Mutable), and ruling planets. Signs sharing the same element are often considered to have an affinity, while opposite signs can create complementary tension. It is important to note that sun-sign compatibility is a simplified lens; a full birth chart comparison — called synastry — provides a much richer picture. Explore sign pairings on the compatibility page.

A birth chart — also called a natal chart or horoscope chart — is a map of the sky at the exact moment and location of a person's birth. It shows the positions of the Sun, Moon, and planets across the twelve zodiac signs and twelve astrological houses. Astrologers use the birth chart as the primary tool for interpretation, going well beyond the sun sign alone. The chart requires a precise birth time and place to be accurate. Use the birth calculator on Orveluna to generate your personal chart.

In Western astrology each zodiac sign is associated with a ruling planet considered its primary symbolic influence. The classical rulerships are: Mars rules Aries, Venus rules Taurus and Libra, Mercury rules Gemini and Virgo, the Moon rules Cancer, the Sun rules Leo, Pluto rules Scorpio, Jupiter rules Sagittarius, Saturn rules Capricorn, Uranus rules Aquarius, and Neptune rules Pisces. Modern astrology added Uranus, Neptune, and Pluto as outer-planet rulers after their discovery. Ruling planets are an interpretive tool, not a physical force.

Orveluna's daily horoscopes are generated from structural signals derived from licensed astronomical data, including the real-time positions of the planets. Those signals are combined with the symbolic archetypes of each zodiac sign to produce individualised readings in eleven languages. The content is designed as a reflective tool within the interpretive astrological tradition — it is not a scientific prediction or a guarantee of any outcome. Read today's horoscope for your sign on the daily horoscope page, or learn about our approach on the methodology page.

The cusp refers to the transition period when the Sun moves from one sign to the next, typically around the 20th or 21st of each month. In Western astrology the Sun occupies exactly one sign at any given moment — there is no recognised "cusp sign" as a separate astrological category. If your birthday falls on a changeover day, the precise time and place of birth determine which sign the Sun was actually in. Use the birth calculator to confirm your sign if you were born near a boundary date.
