What is Time Duration Calculator?
A Time Duration Calculator helps you easily find the difference between two times, with option to subtract breaks. It is especially useful for work shifts, exams, or travel where you want to know the exact time spent.
The tool instantly calculates how many hours, minutes, and seconds elapsed between a start and end time—including cases where the time crosses midnight! No manual calculations or time math needed.
Formula Behind Time Duration Calculator
The duration is calculated as: (End Time in seconds) - (Start Time in seconds) - (Break Time in seconds, if any). If the end time is earlier than the start time, 24 hours are added to handle overnight durations automatically.
