1. What is a Length of Service Calculator?

Definition: This calculator determines the duration between two dates in years, months, or days.

Purpose: It helps HR professionals, employees, and administrators calculate tenure, service periods, or time intervals between events.

2. How Does the Calculator Work?

The calculator uses the formula:

Where:

• \( LOS \) — Length of Service (in selected unit)
• \( \text{End Date} \) — The ending date of the period
• \( \text{Start Date} \) — The beginning date of the period

Explanation: The calculator computes the exact difference between two dates and converts it to your preferred unit (years, months, or days).

3. Importance of Length of Service Calculation

Details: Accurate service period calculation is crucial for benefits eligibility, retirement planning, leave accruals, and employment records.

4. Using the Calculator
