2. How Does the Calculator Work?

The calculator uses a simple date addition formula:

Where:

• Surgery Date — The date when the surgical procedure was performed
• 90 days — Standard global period duration for major procedures

Explanation: The calculation accounts for calendar days (not just business days) and properly handles month/year transitions.
