user16626: I understand that the opening 1. d4 d5 2. c4 e6 3. Nf3 Nf6  is called Queen's Gambit Declined. But how about 1. d4 Nf6 2. Nf3 e6 3. c4 d5? There is no gambit offered, let alone declined. Is it still called Queen's gambit declined?

user23468: This is a transposition, you have to think about the pawn structure instead on focusing on the concrete order, there are thousands of different ways of getting to the same (or quite similar) positions

user18809: They reach the same position, so they have the same name. It wouldn't make sense to call the same position differently depending on the moves that lead to it. 1.f4 e5 2.e4 is a King's gambit, not a declined From's gambit. 1.e4 c6 2.d4 d5 3.cxd5 exd5 4.c4 Nf6 5.Nc3 e6 6.Nf3 is a Tarrasch Defence despite having started as a Caro-Kann

user12873: Yes, it is still called the Queen's Gambit Declined. That's just the name of the system, regardless of the move order used to reach it. However, it is not the QGD before Black chooses to push 3...d5.
