About the Hours Calculator

Our Hours Calculator is a precise and easy-to-use tool designed to compute the exact duration between any two times of day. Whether you need to track work hours for payroll, calculate the length of a shift, or determine how long a meeting lasted, this tool delivers instant and accurate results. It handles both 12-hour AM/PM and 24-hour time formats, making it versatile for any use case.

The calculator automatically accounts for overnight calculations, so you can enter a start time in the evening and an end time the next morning without worrying about midnight crossovers. This makes it ideal for night shift workers, security personnel, and healthcare professionals who often work non-standard hours. Simply input your start and end times, and the calculator provides the total duration in hours and minutes.

Whether you are self-employed tracking billable hours, a manager calculating employee overtime, or a student managing study sessions, this tool simplifies time arithmetic. No manual math required — just enter the times and get your answer instantly.

How to Use the Hours Calculator

Using the Hours Calculator is simple and straightforward. Follow these steps to get accurate results:

• Enter your start time in the first field using either 12-hour (e.g., 8:30 AM) or 24-hour format (e.g., 08:30).
• Enter your end time in the second field in the same format.
• Click the Calculate button to instantly see the duration in hours and minutes.
• The result will display the total time difference, including fractional hours if applicable.

For overnight shifts, simply enter the evening start time and the next morning end time. The calculator handles the midnight crossover automatically. You can use the Clear button to reset the fields and perform a new calculation.
