I've noticed that Alexa often fills an AMAZON.DATE slot without the day.
For example, if the user says, "December 25", my skill (usually) receives the string "2020-12".
However, if the user instead says "December 25th", my skill receives the correct string ("2020-12-25").
Is there a way to allow Alexa to correctly interpret a date in either case? Quite a few users of my skill have complained about this behavior.
It looks like others are experiencing this as well: https://forums.developer.amazon.com/questions/235234/amazondate-returns-january-11-as-2021-01.html
