It is my best friends bday next week. I know that but I am confused between dates 😬

What should I do. Can't ask her obvy 😬

Assistant prof, dabbles in art at times.
She/her

That's some solid plan! 

I just went to fb and checked 😂

Check her telegram Id the entire week if she has one, it notifies on that day(only if she had uploaded the date). Your or some mutual friend's insta story archive for a birthday story/post. Search for happy birthday on the chat, see if you can find the last birthday wish that you sent. 
Ask her for an id card under some random premise (last resort)
