Really worried, did I get the job or not?

So I had an interview yesterday at 4:30pm and the manager said he would call me back later that night or either or today letting me know if I got the job and its 3pm here and he still hasn't called. I know he said either yesterday OR today but I feel like if he wanted me to work there he would have called last night or earlier today. I'm kind of sad and worried. What is your opinion? :(
