Naturally, sighted people can just allow Siri to set the event on the wrong day and correct it later manually, but this is not an option for the visually disabled.
*sigh* Okay. Figures. Just keep on telling people that all blind people can do with their iPhone is talk to Siri. So tiring and insulting. Like yes this bug is important. Yes it should be fixed. But blind people have got to be able to use VoiceOver if Siri doesn’t work, or breaks, or can’t read your voicemail, or whatever Apple does to it.
