In a normal year of 365 days, how many complete weekends (Saturday–Sunday pairs) are there?

Introduction / Context:
This question tests whether you can relate the total number of days in a year to the number of full weeks and therefore to the number of weekends. In most practical contexts, a “weekend” is considered to be one Saturday–Sunday pair within a single week.

Given Data / Assumptions:

• The year considered is a normal year with 365 days (not a leap year).
• Each week has 7 days: Monday to Sunday.
• A complete weekend consists of one Saturday and the following Sunday.

Concept / Approach:
We first determine the number of full weeks in a 365-day year by dividing by 7. Each full week has exactly one Saturday and one Sunday, hence one complete weekend. Any remaining days after counting full weeks might contribute extra Saturdays or Sundays but will not form an additional complete weekend unless they form a full pair within the same week.

Step-by-Step Solution:
Step 1: Compute the number of full weeks in a year: 365 / 7 = 52 weeks with a remainder of 1 day.Step 2: Each of these 52 full weeks has exactly one Saturday and one Sunday.Step 3: Therefore, each full week contributes one complete weekend.Step 4: The total number of complete weekends is therefore 52.Step 5: The extra 1 day beyond the 52 full weeks may or may not be a Saturday or Sunday, but by itself it cannot form a full weekend pair.

Verification / Alternative check:
Think of lining up the year into 52 blocks of 7 days. Each block is exactly one week, containing all days from Monday through Sunday, and hence exactly one Saturday–Sunday pair. After these 52 blocks, one extra day remains. This lone day cannot create another full weekend pair because it would require two consecutive days (Saturday and Sunday) to do so.

Why Other Options Are Wrong:
53 or 104 weekends overestimate the number of full Saturday–Sunday pairs. 103 is actually the total count of Saturdays plus Sundays in some years, not the number of paired weekends. 51 underestimates the minimum number of Saturdays–Sundays, because 52 full weeks guarantee at least 52 such pairs.

Common Pitfalls:

• Confusing the number of Saturdays and Sundays separately with the number of weekend pairs.
• Assuming every extra day or two adds a new “weekend”, even if the pair is incomplete.
• Not dividing the total days by 7 to find full weeks first.

Final Answer:
There are 52 complete weekends in a normal year.
