Chinese calendar
--------------
The Chinese calendar is a traditional cultural tool that integrates elements
such as the lunar calendar, solar terms, and traditional festivals. It is
widely used in Chinese social life, helping people understand the dates of
the lunar calendar, arrange festival activities, and inherit the excellent
traditional culture of the Chinese nation. Whether in families, businesses,
or education, the Chinese calendar plays an irreplaceable role, enabling
people to better understand and appreciate the charm of Chinese traditional
culture.
If you want to use the Chinese calendar, please
use :cpp:expr:`lv_calendar_set_chinese_mode(calendar, true)` to enable it.
