1. What is Post Op Day?

Post Op Day (Postoperative Day) is the number of days that have passed since a surgical procedure. It's an important metric for tracking patient recovery, medication schedules, and follow-up care timelines.

2. How Does the Calculator Work?

The calculator uses a simple date difference calculation:

Where:

• Current Date — Today's date or any specified date
• Surgery Date — The date when the surgical procedure was performed

Explanation: The calculation counts the full days between the surgery date and current date.

3. Importance of Post Op Day Calculation

Details: Accurate postoperative day counting is crucial for monitoring recovery milestones, medication schedules (like antibiotics or pain management), wound care protocols, and determining when sutures or drains should be removed.

4. Using the Calculator
