So I asked "What month is it?" of Siri on these of my devices: MacBook Pro, iPad Pro, Original Large Home Pods, and AppleTV streamer, and they ALL came back with "Friday, March 21, 2025". Only my iPhone 15 Pro could not answer the question in either voice or text modes, responding with "Sorry, I don't understand".
Therefore something seems to be amiss with the iPhone's parsing of the English word "month" when preceded with the words 'what' or 'which' before it is sent to the cloud for translation and response. If the question to the iPhone Siri is phrased "What is today's date?", it comes back with the exact same answer as the other devices mentioned above.
Yet if I ask my iPhone Siri "What does the word 'month' mean?", it responds with "Each of the twelve named periods into which a year is divided". I then asked my iPhone Siri "What is the month?" and it came back with a discussion of moon cycles. When I asked "how is the word 'month' spelled? it came back with "M, O, N, T, H." Yet when I asked my iPhone Siri "How are today's month and today's date related" it then asked if I wanted to have it submit the question to ChapGPT and I said "yes" resulting in this response: "Today's month (March) and today's date (21st) together represent the United Nations' International Day for the Elimination of Racial Discrimination, which is observed annually on March 21st." Finally I asked my iPhone Siri: "What is the M, O, N, T, H?" and it responded with a dictionary definition of the word month."
So if I want to know the current month from my iPhone Siri (if I ignore the fact that it's always present on the lockscreen) then I merely ask: "What is today's date?"
In German "Was ist die Uhr?" (literally 'What is the clock?') is their way of asking "What time is it? When I asked my iPhone Siri "What is the clock" it came back with the correct time. Go figure.
