Usage of the Gregorian Calendar

The Gregorian calendar is the name of the chronological system. This chronological system uses the birth of Jesus as the first year of AD, and those before the first year of AD are called BC. The so-called year 2021 is two thousand and twenty-one years starting from the first year of the Christian era. It should be noted that although 0 is a natural number, there is no year 0 BC or AD 0. The year after 1 BC is 1 AD, which is the first year of AD.

Although BC dates are counted backwards, and the later numbers are smaller than the previous ones. For example, 202 BC when the Western Han Dynasty was established was later than 221 BC when the Qin Dynasty was established. The months of the year are still numbered correctly, with January in front and December in the back, and the same goes for the dates, with the first day of the lunar month in front and the fifteenth in the back.
