How do I calculate the time between two times?

Enter your start time and end time. The calculator shows the difference in hours and minutes. If the end time is earlier than the start time, it assumes the end time is on the following day.

Does this work with 24-hour time?

Yes. Enter times in 24-hour format (e.g., 14:30 for 2:30 PM) or 12-hour format with AM/PM. The calculator handles both.

How do I calculate work hours between two times?

Enter your start time (e.g., 09:00) and end time (e.g., 17:00). The result shows 8 hours 0 minutes. For shifts that span midnight, the calculator automatically adjusts — entering 22:00 to 06:00 gives 8 hours.

Can I use this for tracking study or project time?

Yes. The calculator works for any time tracking: study sessions, meeting durations, travel time, cooking, exercise, or project work. Just enter your start and end times.
