1. What is Weeks Before Date Calculator?

The Weeks Before Date Calculator calculates the number of weeks between a target date and the current date. It helps in project planning, event countdowns, and time management by providing the exact number of weeks remaining or passed.

2. How Does the Calculator Work?

The calculator uses the simple mathematical formula:

\[ Weeks = \frac{(Target\ Date - Current\ Date)}{7} \]

Where:

\( Target\ Date \) — The future or past date you want to calculate from
\( Current\ Date \) — Today's date or any reference date
\( 7 \) — Number of days in a week

Explanation: The calculator first calculates the difference in days between the two dates, then divides by 7 to convert to weeks. The result shows either weeks remaining or weeks passed.

3. Importance of Weeks Calculation

Details: Calculating weeks between dates is essential for project timelines, academic schedules, vacation planning, pregnancy tracking, and any situation requiring precise time measurement in weekly increments.

4. Using the Calculator

Tips: Enter the target date and current date in the format YYYY-MM-DD. The calculator automatically determines whether the result represents weeks remaining or weeks passed based on the date comparison.
