It was ordered by westerners, and people in Hong Kong and Taiwan also called it the Gregorian calendar.
Lunar calendar (lunar calendar): Except Gregorian calendar (solar calendar), China has kept the calendar that has been used since the Xia Dynasty. The lunar calendar takes the period of the moon as one month and 12 months as one year.
It takes period of revolution with twelve moons as a year, ten days less than a return. So they are consistent by setting leap, which is called lunar calendar (the moon is called lunar calendar). It also contains calendar knowledge such as 24 solar terms, which is closely related to agricultural production, so it is also called lunar calendar.

The relationship among solar calendar, lunar calendar and lunar calendar
1, the lunar calendar is a lunar calendar, but the lunar calendar is not just a lunar calendar. The lunar calendar handed down in ancient China is a combination of yin and yang, including the lunar calendar recorded by the moon cycle, represented by the "full moon on August 15th". It also includes "Tomb-Sweeping Day", which is represented by "solar terms" and always falls on April 5th every year.
So we often see the saying "the seventh day of the seventh lunar month, the ninth day of the summer" on the calendar. The seventh day of the seventh month of the lunar calendar is the lunar calendar representation in the lunar calendar, while the ninth day of the summer is the solar calendar representation in the lunar calendar.
Literally, the solar calendar is the abbreviation of "solar calendar". The lunar calendar is divided into lunar calendar and solar calendar, which is such a representation. However, since the adoption of the western "AD calendar", the current solar calendar is basically dedicated to the "AD calendar", that is, the "solar calendar".
This is mainly related to our habits. Because most date records and festivals in China are defined according to the lunar calendar in the lunar calendar. For example, "New Year's Eve" is the thirtieth day of the twelfth lunar month, and 2008 is the first day of the first month. Dragon Boat Festival and so on. It seems that there is only one "Tomb-Sweeping Day" that is not a festival.
The solar calendar of the lunar calendar is 24 solar terms, mainly serving agricultural production. Speaking of it, the solar calendar in the lunar calendar can better represent the title of "lunar calendar"
