Fucking participants!
This problem is the most stupid problem I have ever seen.
Why the problem is to output the calendar but not to find the day of
week? It is very simple to find but it is IMPOSSIBLE to output! The
sample does not give the answers to many questions.
Why I MUST GUESS, GUESS and GUESS again?

I think, you're wrong. The format of output data is rather clear, and
the only thing, not mentioned in the problem statement is that one
has to output [.n] when current date is less than 10.

IMHO problem 1177 is rather worse from this point of view.

Jesus Christ !!! I had thought that maybe that was why (putting a space to the left between the brackets when the number had a single digit) that WA had in test2, but I didn't believe it. In fact I assumed that in this problem the spaces were irrelevant.
I find it terrible!, "[1]" incorrect and "[ 1] ([.1])" correct, for such nonsense one should not have a WA, much less if the problem does not specify it explicitly.
And it is a pity because it is a beautiful problem.
Thanks for clarifying this.
