What happens when you ask Siri to set a reminder that far in the future? Do you see it show up in Reminders? If you do, then you can ask Siri what your reminders are on any given day and it will tell you. At this point, Siri will not, without you prompting it, remind you of something audibly. You might be able to set something up with Shortcuts.
