How many years is it today?

This year is 2022, the Gregorian calendar year, with a total of 365 days and 53 weeks. The lunar calendar that we have used since ancient times is also called the Old Yellow Calendar. According to this calendar, the calendar year is 47 19.

This gives 47 19. At the end of the Qing Dynasty and the beginning of the Republic of China, after repeated research by a large number of experts and scholars, it was confirmed that the Yellow Emperor officially ascended the throne in 2697 BC (some people think it was before 2697), so this year was designated as the first year of the Huangli calendar. Therefore, based on this, the following year of the Gregorian calendar is determined as: 2697+ AD years. This year is 2022 AD, the solar calendar adds up to 47 19, and the Gregorian calendar year is a sad and ugly year.

The difference between solar calendar and lunar calendar

1, different sources

Gregorian calendar = Gregorian calendar is a universal date, which is our usual date.

Lunar calendar = lunar calendar, which is the date used for farming in ancient China, that is, the date indicated by the small print at the bottom of the calendar.

2. Different algorithms

The solar calendar is a calendar in which the earth revolves around the sun for one year.

Lunar calendar is a calendar in which the lunar (moon) moves around the earth as a month and 12 months as a year (leap year is 13 months) (leap month adjusts the four seasons).

Conversion between Gregorian calendar and lunar calendar

Many people have been looking for formulas to change the lunar calendar. However, due to the instability and irregularity of the moon's rotation, there is no formula to find, that is to say, there is no calculation method for the conversion between the Gregorian calendar and the lunar calendar, which is also the reason why the calendar must be changed every hundred years in ancient China.
