Why doesn't Apple's mobile calendar have 24 solar terms?

There is no 24 solar terms in Apple's mobile phone calendar because 24 solar terms originated in China, and the manufacturer of Apple's mobile phone is the United States. The date calendar in the United States is not set according to the holiday standards in China, so the calendar of Apple's mobile phone does not have the unique 24 solar terms in China.

The current calendar is actually an annual calendar that records the dates of a specific solar calendar or lunar calendar within a certain time range, which is convenient for people in need to inquire and use.
