    grammar tenses

    Could someone tell me the difference between the following:

    1) We had been working for 3 hours.
    2) We have been working for 3 hours.

    1) I had not eaten for 24 hours.
    2) I have not eaten for 24 hours.

    Which is correct? Can I use either to mean the same?

    1) I hadn't worked since last December
    2) I haven't worked since last December

    Thanks very much in advance to those who reply.

    I have a very hard time understanding English grammar tenses. I have tried reading grammar books, but I am still confused.

    Re: grammar tenses

    We had been working for three hours when he came.

    He came in the past. We started working three hours before he came and worked continuously until he came. It could all happen years before the uttering of the sentence.

    We have been working for three hours.

    We started working three hours ago. Now (at the moment when the sentence is uttered) it is three hours after we started working. We worked continuously until now.
