Hi!

Did is the past tense for the verb "do", meaning to perform an action. 
Ex. I did my homework. 
      I did the laundry for my mother.
Had is the past tense for the verb "to have", meaning to have possession of something.
Ex. I have a lot of money.
      I have a shirt from Japan.
It can also be used in a phrase like: 
Ex. I have to work many hours on Friday.
