The twelve constellations are divided according to the Gregorian calendar, also called Gregorian calendar, which is an international calendar. In astronomy, the Gregorian calendar refers to a calendar arranged mainly according to the annual movement of the sun. It has about 365 days in a year. The solar calendar is based on the running cycle of the direct point of the sun, and its average calendar year is the tropic year. There are two kinds of calendar years, one is the normal year, the other is the leap year, and the leap year is only one day away from the normal year. This kind of solar calendar is universal all over the world, so it is also called solar calendar.
