Siri has switched the autumnal & vernal equinox

For some reason Siri has confused the northern hemisphere with the southern hemisphere. I live in the US state of Ohio & Siri has switched the autumnal & vernal equinox’s! When asked when the first day of autumn is, she responds March 19, when asked when the first day of spring is she responds September 23, say it isn’t so! I have iPhone 14 Pro Max, location services ON & running iOS 17.6.1…..

What’s up with this?
