Understanding Date Calculations
When calculating the difference between dates, there are several ways to measure time:

- Weeks: Complete 7-day periods plus remaining days
💡 Pro Tip: Leap Years
When calculating days between dates spanning a leap year (like 2024), February has 29 days instead of 28. This calculator automatically accounts for leap years in all calculations.
