1. What is the Service Computation Date Adjustment?

The Service Computation Date Adjustment calculates length of service per OPM (Office of Personnel Management) guidelines. It determines the exact years, months, and days of federal service for retirement, leave accrual, and other benefits.

2. How Does the Calculator Work?

The calculator computes the difference between two dates following OPM guidelines:

Where:

• Start Date — The beginning date of service
• End Date — The ending date of service

Explanation: The calculation accounts for full years, months, and days according to OPM standards for federal service computation.

3. Importance of Length of Service Calculation

Details: Accurate service computation is essential for determining federal retirement eligibility, calculating annuity benefits, leave accrual rates, and within-grade increases.

4. Using the Calculator

Tips: Enter the start date and end date of service in the format YYYY-MM-DD. Ensure dates are valid and the end date is after the start date.
