What are the dates of the zodiac signs, lunar or new?

Constellations are calculated according to the solar calendar Because constellations are the twelve constellations on the path of the sun (i.e., the ecliptic), which is the solar calendar The zodiac is the area where the orbit of the sun is seen from the Earth, extending an octave to both sides. There are the "return ecliptic" in Western astrology, which is counted by the vernal equinox, and the "sidereal ecliptic", which is marked by fixed stars in Indian astrology. The ecliptic is the path of the sun in the sky during the year, and it is also the starry path of the great circle formed by the earth's orbital plane in the celestial sphere.

Ancient astronomers divided these constellations into 18, 14, and 12 constellations. Ancient Babylonian astrology regarded the zodiac signs, which are easier to divide into 12 equal parts of 30 degrees, and took different constellation totems according to different symbolic patterns (such as Sagittarius, Leo, etc.). The sun is "yang", and the calendar set based on the sun's apparent motion is called "solar calendar"; The moon is "yin", and the calendar set based on the apparent motion of the moon is naturally called the "lunar calendar" The Chinese lunar calendar is a lunisolar calendar The lunar calendar is a traditional calendar adopted by our country, also known as the summer calendar, the middle calendar, and the old calendar, and the folk also call the lunar calendar.

It uses a strict synodic cycle to determine the month, and uses the method of setting leap months to make the average length of the year similar to the return year, and has the properties of both lunar months and solar years, so it is essentially a lunisolar calendar. The lunar calendar takes the date of the conjunction of the sun and the moon (the sun and the moon have equal ecliptic longitude) as the first day of the month, that is, the first day of the new month. The average length of a synic month is about a day, so some months have 30 days.

Weigh the moon big; Some months are on the 29th, which is called the small month. The date of the beginning of the month is calculated according to the position of the sun and moon and is not mechanically arranged. The lunar calendar takes 12 months as a year, with a total of 354 or 355 days, a difference of 11 days from the return year.

To this end, it is coordinated by inserting seven leap months every nineteen years. The arrangement of the leap month is determined by the 24 solar terms. The Gregorian calendar is also the national calendar.

The new calendar, also known as the Gregorian calendar, is also called the solar calendar in some places.

Constellations are counted according to the Gregorian calendar (new calendar) birthdays, which are translated in the English-Chinese dictionary as follows: "signs."

In fact, the origin of this constellation is similar to that of the West and the East, and the lunisolar calendar arrangement is different. More than 2,000 years ago, the Greek astronomer Hiparchus (190 120 BC) divided the ecliptic into 12 segments with the vernal equinox at 0°, every 30° from the vernal equinox (i.e. zero degrees on the ecliptic).

It is a house and is named after the main constellations contained in each house at that time.

The zodiac signs are divided according to the solar calendar. The zodiac sign for February 20 in the solar calendar is:

Pisces. The zodiac sign for July 2 is:

Cancer.

The solar calendar corresponds to the horoscope table Cancer.
