1. What Is The Weeks Calculator?

The Weeks Calculator accurately calculates the number of weeks between two dates, accounting for leap years in the calculation. It provides precise results for any date range.

2. How Does The Calculator Work?

The calculator uses the following formula:

Where:

• \( Date1 \) — Start date
• \( Date2 \) — End date
• The difference is calculated in days (including leap year days)
• Result is divided by 7 to get weeks

Explanation: The calculation automatically accounts for leap years (years divisible by 4, except for years divisible by 100 unless also divisible by 400) when determining the number of days between dates.

3. Importance Of Accurate Week Calculation

Details: Precise week calculations are essential for project planning, pregnancy tracking, financial calculations, and any time-sensitive scheduling that spans multiple years.
