12 months in a year
Abstract an array

c = [摩羯，水瓶， 双鱼，白羊，金牛，双子，巨蟹，狮子，处女，天秤，天蝎，射手，摩羯]

c is a list of months
The starting month corresponding to the Aquarius with the serial number 1 in the array isJanuary
The serial number is Starting month or (Ending month - 1)
The constellation corresponding to the dateThe starting month is the date The month or the ending month is the month (that is, the starting month is the month -1 of the date)
In order to get the constellation corresponding to the date, we calculate the start of the corresponding constellation through the date Month

startMonth = month - [(day < Date[month]) ? 1 : 0]
c = [摩羯，水瓶， 双鱼，白羊，金牛，双子，巨蟹，狮子，处女，天秤，天蝎，射手，摩羯]
index = [0, 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12]
Date = [22, 20, 19, 21, 21, 21, 22, 23, 23, 23, 23, 22, 22]

startMonth - the calculated starting month of the corresponding constellation;
Month - the month corresponding to the date;
day - the number corresponding to the date;
Date - the date corresponding to the month list List;

Explanation:
Corresponding constellation starting month = current month - [(whether the current date is less than the date of the corresponding month), if yes, it is 1, otherwise it is 0]
Judge (date corresponding number Number < The starting month is the starting number of the zodiac sign corresponding to the month)
Example February 18th is Aquarius and February 19th is Gemini
18 < 19 (19 is Pisces in February Starting date) If less than true, 2 - 1 = 1. The corresponding zodiac sign for January is Aquarius
19 = 19. If less than true, 2 - 0 = 2, so the corresponding zodiac sign for February is Pisces

Simplified list Cancel the date list
day < Date[month] =》 day - x < Date[month] - x
Let y = Date[month] - x, y needs to be a single digit
From now on The minimum number corresponding to the start date is 19th (Pisces) and the maximum is 23rd (Leo)
Exhaustive and list the table
