"My birthday is June 19th."
This is one of the sentences that made me feel everything in this course is for conversation only.
Make sure you use 日 not 号 when you write a date.
Not disagreeing, but why is that?? Duo lingo doesn't have a grammar course beyond tapping on the words to look at their meaning, this app kinda needs you to have some sorry of basic knowledge of grammar and sentence structure.
Hm... I don't catch your meaning well... Anyway I do not have a problem if Duo wants to teach conversational uses only and there must be people out there who only want to learn how to talk. I only think it is important for learners to know what they are learning.
Yeah, I used 日 instead of 号 and got dinged for it... This is one of those times when Duolingo needs to make its expectations clearer.
