Why does the lunar calendar of grapefruit not match?

There are several reasons why grapefruit lunar calendar does not match:

1, calculation algorithm error. The lunar calendar conversion algorithm is complex, and there may be errors or inaccuracies in programming, resulting in inconsistent lunar calendar information.

2. Time system error. Because of the difference in time calculation and statistics, the fixed calendar and solar terms do not correspond completely, and there is a time difference. If the program does not consider these time differences, it may lead to errors in the lunar calendar calculation formula.

3. The database was not updated in time. The update of lunar calendar information depends on the update of data. If the data is not updated in time, errors will accumulate and lead to inaccuracy.
