What's the difference between lunar calendar, solar calendar, lunar calendar and solar calendar? Which one counts everyone's birthday and birthday? Thank you for your questions.

Lunar calendar = lunar calendar = solar calendar We mainly use the international calendar, namely the Gregorian calendar. It takes a tropical year as a year and then divides it into twelve months (the number of months is 3 1 day, 30 days and 29 days, all of which are manually designated), which is called the solar calendar, that is, the solar calendar. It was ordered by westerners, and people in Hong Kong and Taiwan also called it the Gregorian calendar. In addition to the Gregorian calendar, China also retains the calendar that has been used since the Xia Dynasty-the Summer Calendar, in which twelve moons revolve once a year, so that the time of a year is ten days less than that of a tropical year. Therefore, passing the leap test 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. As can be seen from the above, the solar calendar and the lunar calendar are just two different ways to record time. No matter whether the lunar calendar or the solar calendar is reported, it must be converted into the punctuality of heavenly stems and earthly branches before calculation can be made. The blind fortune teller arranges heavenly stems and earthly branches according to the formula compiled by the lunar calendar, and gives him the lunar calendar. At present, there are perpetual calendars of yin and yang. You can report the lunar calendar or solar calendar at will to see its corresponding heavenly stems and earthly branches. Everyone's birthday is calculated according to how it is calculated locally. Some places are lunar calendars, while others are solar calendars.
