1 answer

All of them are correct.

In # 1, the implication was that you went to India, but probably didn't travel around there. You may have visited only one city.

In # 2, you've indicated that you traveled in several places in India.

# 3 is not usually used.

# 4 is usually used in the U.S.

# 5 is more common in the U.K. and other parts of the world. I think, though, that they say 5 July 2009.
