Ignorant vs. oblivious

Hello everbody, how are you today? (Today is Friday the 13 so beware ;-)).
Anyway, I wanted to ask you to tell me the difference between ignorant and oblivious. I understand that ignorant describes a person who does not know much and oblivious means the person is not aware of something. Is that correct?
Thank you!

Hello Jamie (K),

Thank you for your prompt and useful response. Now I know how to distinguish between both adjectives. By the way, I’ve read the other posts you have made here and it seems to me you are a teacher or professor of English. Am I right?
