Mercury is shown in the solar or lunar calendar.

The constellation looks at the solar calendar. When everyone is born, every planet in the solar system, regardless of its size, including sun, moon, Venus, Jupiter, Mercury, Mars, Saturn, Neptune, Uranus and Pluto, runs at different angles and distances, so each planet and its corresponding 12 constellation are mutually causal. Note: We should adopt a scientific attitude towards horoscope, believing rather than superstitious.

The sun sign is the most frequently mentioned in astrology. As long as you know a person's date of birth, you can find out his sun sign. The twelve constellations begin in spring, that is, when the sun runs to the vernal equinox around March 20 every year, they will be sorted in order: Aries, Taurus, Gemini, Cancer, Leo, Virgo, Libra, Scorpio, Sagittarius, Capricorn, Aquarius and Pisces.
