Introduction: ADP (Automatic Data Processing) is a prominent provider of payroll and HR solutions, and understanding how ADP calculates time is essential for accurate time tracking and payroll processing. In this article, we’ll delve into the method ADP uses to calculate time and provide a practical ADP Time Calculator to help you determine total hours worked using the same method.

Formula: ADP typically calculates time by taking the difference between the start time and end time. The formula for this calculation is as follows: Total Time = End Time – Start Time

The result is provided in hours and minutes.

How to Use:
