Question

can anyone tell me what is the difference between "have" and & "did". And also tell where to use it.

Answer 1

'Did' is the simple past tense of the verb 'do' and 'have done' is the present perfect tense.

Whenever you refer to any event that has occurred in the past, you use simple past tense to describe it. It only states that the action was performed by someone in the past.

You use present perfect tense to showcase that the action you are referring to is done in the present and that the Action is now completed. This means that the action began in the near past and is completed in the present.

So in a way simple past signifies the doing of an action in the past whereas present perfect represents its completion in the present.

Hope it helps you..
