How does siri calculate days?

Enter a date and check the remaining days of the selected date to download and add it to My Quick Help. Later, you can start it with Siri voice password: "Hey Siri, automatically count the days", and he will count the days.

Siri can support natural language input, and can call the weather forecast, schedule, search data and other applications that come with the system. It can also learn new sounds and intonations continuously and provide conversational response. Siri can turn iPhone4S and above into intelligent robots. At the 20 17 Apple WWDC Developers Conference, Siri updated the real-time translation function, supporting English, French, German and other languages, and will support it in the future.
