Check whether the birthday calendar is accurate.

The expert said: Don't take it too seriously.

Xu Hualong, an expert of Shanghai Intangible Cultural Heritage Protection Group, said that the Gregorian calendar is one of the earliest calendars, which put the contents of agricultural life into the calendar according to the changes of the four seasons and gradually became the criterion of agricultural activities.

Xu Hualong also introduced that it was later that marriage and other contents entered the Gregorian calendar. In the farming era, these contents were completely ignored. The ancients put what they thought was compatible and suitable on the agenda, forming the yellow calendar, just to adjust people's lives with this combination of natural science and social science.

The farming society has changed for a long time now, and the social environment and life content are far apart after all. Therefore, the contents related to agriculture in the ancient yellow calendar have disappeared, and only those neglected in the past, such as marriage and tourism, have continued to this day.

Xu Hualong told reporters that in order to attract consumers, today's producers of the yellow calendar imitate the form of the yellow calendar and join other contemporary people's concerns about moving and getting money. Since today's almanac has become a new trick for later generations to play with the old template, it is not surprising that the versions are different.

But in any case, citizens need not take it too seriously. If the Gregorian calendar says "everything doesn't agree", it is impossible for everyone to do anything on this day.
