1. What is Weeks Between Dates Calculation?

The Weeks Between Dates calculation determines the number of full weeks between two dates. This is useful for project planning, pregnancy tracking, academic scheduling, and other time-sensitive activities.

2. How Does the Calculator Work?

The calculator uses the following formula:

Where:

• \( Date1 \) — The start date
• \( Date2 \) — The end date
• The difference is calculated in days
• The floor function gives whole weeks only

Explanation: The calculation first determines the total number of days between the two dates, then divides by 7 (days in a week) and rounds down to the nearest whole number.

3. Importance of Weeks Calculation

Details: Knowing the exact number of weeks between dates helps in precise planning, scheduling, and tracking of events, projects, or developmental milestones.

4. Using the Calculator

Q4: Can I calculate weeks between dates far in the past or future?
A: Yes, the calculator can handle any valid dates within the range supported by your browser.

Q5: How precise is this calculation?
A: It's precise to whole weeks. For more granular time measurements, consider using days or a days calculator.
