Understanding how many weeks are in a year is a simple yet fundamental question. While most of us generally accept that there are **52 weeks in a year**, let's take a closer look at the details and variations.

## The Basics: Weeks and Years

### 1. **Standard Year**

A standard year consists of **365 days**. To find the number of weeks in a standard year, we can perform the following calculation:

[ \text{Weeks} = \frac{\text{Days in a Year}}{7} = \frac{365}{7} \approx 52.14 ]

This means that a standard year has **52 complete weeks** and **1 extra day**.

### 2. **Leap Year**

Every four years, we add an extra day to the calendar to account for the slight discrepancy in the Earth's orbit around the Sun. This is known as a **leap year**. A leap year consists of **366 days**. Here’s how it breaks down:

[ \text{Weeks} = \frac{366}{7} \approx 52.29 ]

Thus, a leap year has **52 complete weeks** and **2 extra days**.
