The origin of solar calendar and yellow calendar

Because the Gregorian calendar was originally called the Gregorian calendar, it became the Gregorian calendar, so it is very interesting. In fact, the so-called lunar calendar is our traditional calculation method, while the solar calendar is an international name. Some major festivals in China are basically calculated according to the lunar calendar, such as the Spring Festival and Mid-Autumn Festival. Some foreign festivals are calculated according to the solar calendar, such as Halloween or Christmas. In ancient China, everyone calculated according to the lunar calendar, but later, in order to connect with the world, they adopted the algorithm of foreigners. It was called "foreign calendar" at that time, and it became "solar calendar" over time.

In fact, the most important thing about farming is the calendar, because the crops planted all year round are different, and which season is suitable for planting which crops is very particular, so in ancient times, our ancestors had already worked out a set of calendars themselves, which is what we now call the lunar calendar. The earliest lunar calendar was also called the solar calendar by the ancients, because this calendar was calculated completely according to the law of sunrise or sunset.

The solar calendar mainly comes from Christianity. Now most western countries actually calculate according to the solar calendar. Generally speaking, the difference between solar calendar and lunar calendar is about 50 to 65 days. Therefore, the Spring Festival in China is usually in February of the solar calendar. The biggest difference between the solar calendar and the lunar calendar is that the lunar calendar has leap months, but the solar calendar does not.

During the feudal rule of China, the lunar calendar was also called the imperial calendar. With the geological end of 19 12, the imperial calendar became the old yellow calendar. Now people usually call the lunar calendar the lunar calendar. In fact, it is remarkable that our ancestors were able to calculate these calendars containing the wisdom of the ancients.
