This question is very simple, because only when March 1 is Friday, or March 1 is Thursday, or March 1 is Wednesday, there will be four Tuesdays and five Fridays in March. So March 1 is (Wednesday or Thursday or Friday)

Math: 3 1÷7=4 (weeks) ... 3 days

The remaining three days may be Friday, which can satisfy the meaning of the question. That is, March 29th, March 30th, March 3rd1may be Friday.

So March 1 is Friday, and March 29th is Friday.

Similarly, March 1 is Thursday, and March 30th is Friday.

March 1 is Wednesday, and March 3 1 is Friday.
