1. What is Weeks and Days Calculation?

The Weeks and Days Calculator calculates the exact number of weeks and remaining days between two dates. This is useful for project planning, pregnancy tracking, and various time-based calculations.

2. How Does the Calculator Work?

The calculator uses the following formulas:

Where:

• \( \text{Date1} \) — The starting date
• \( \text{Date2} \) — The ending date
• \( \left\lfloor \right\rfloor \) — Floor function (rounds down to nearest integer)
• \( \mod \) — Modulo operation (returns the remainder)

Explanation: The calculator first calculates the total days between two dates, then divides by 7 to get weeks, and uses modulo to find remaining days.

3. Importance of Date Difference Calculation

Details: Calculating weeks and days between dates is essential for project management, event planning, financial calculations, and various personal and professional scheduling needs.

4. Using the Calculator

Tips: Select both dates using the date picker. Date1 should be earlier than Date2. The calculator will automatically compute the weeks and days difference.
