An Hours Calculator is a simple online tool that helps you quickly find out the duration between two times. Instead of manually counting hours and minutes, this calculator instantly shows you the exact difference in hours, minutes, and seconds. Whether you are tracking working hours, studying, exercising, or planning travel, this tool makes the process effortless.
Simply enter a Start Time and an End Time. The calculator finds the difference by converting both times into seconds and subtracting them. If the end time is earlier than the start time, the tool assumes the calculation continues into the next day (useful for night shifts).
Suppose you start work at 09:15 AM and finish at 05:45 PM. The calculator shows:
✅ Yes. If you enter a start time of 10:00 PM and an end time of 06:00 AM, the calculator will return 8 hours.
✅ Yes. The tool shows decimal hours (e.g., 7.5 hours = 7 hours 30 minutes).
✅ Absolutely. Employers and employees can use it to calculate daily or weekly work hours.

The tool is perfect for personal, educational, or professional use. Whether you’re calculating payroll, planning study sessions, or tracking workouts, this free online calculator has you covered.
