Solve the programming task below in a Python markdown code block.
A particular month has 30 days, numbered from 1 to 30.

Day 1 is a Monday, and the usual 7-day week is followed (so day 2 is Tuesday, day 3 is Wednesday, and so on).

Every Saturday and Sunday is a holiday. There are N festival days, which are also holidays. Note that it is possible for a festival day to occur on a Saturday or Sunday.

You are given the dates of the festivals. Determine the total number of holidays in this month.

------ Input Format ------ 

- The first line of input contains a single integer T, denoting the number of test cases. The description of T test cases follows.
- The first line of each test case contains an integer N denoting the number of festival days.
- The second line of each test case contains N distinct space-separated integers A_{1}, A_{2}, \ldots A_{N}, denoting the festival days. Note that the A_{i} are not necessarily given in sorted order.

------ Output Format ------ 

For each test case, output a new line containing the total number of holidays.

------ Constraints ------ 

$1 ≤ T ≤ 1000$
$1 ≤ N ≤ 30$
$1 ≤ A_{i} ≤ 30$
- All the $A_{i}$ are distinct

Test Case $1$: Days $6, 13, 20$ and $27$ are Saturdays, and days $7, 14, 21, 28$ are Sundays. The festivals fall on day $5$ and day $7$, but day $7$ is already a Sunday. This gives us $9$ holidays in total — days $5, 6, 7, 13, 14, 20, 21, 27, 28$.

Test Case $2$: Days $6, 13, 20$ and $27$ are Saturdays, and days $7, 14, 21, 28$ are Sundays. The festivals fall on day $1$, day $6$, and day $23$. This gives us $10$ holidays in total — days $1, 6, 7, 13, 14, 20, 21, 23, 27, 28$.

Test Case $3$: Days $6, 13, 20$ and $27$ are Saturdays, and days $7, 14, 21, 28$ are Sundays. The only festival is on day $13$, which is already a holiday. This gives us $8$ holidays in total — days $6, 7, 13, 14, 20, 21, 27, 28$.
