1. What is the Post Op 90 Day Calculator?

The Post Op 90 Day Calculator determines the end date of the 90-day postoperative period by adding 90 days to the surgery date. This timeframe is commonly used in clinical studies and recovery assessments.

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 postoperative monitoring period

Explanation: The calculation accounts for all calendar days (including weekends and holidays) in the 90-day period.

3. Importance of Post-Op Timeframe

Details: The 90-day postoperative period is critical for monitoring surgical outcomes, complications, and recovery progress in many medical specialties.

4. Using the Calculator
