## Definition

A time calculator is a utility that performs arithmetic operations on hours, minutes, and seconds. The calculator adds or subtracts time intervals, handles conversions between different time units, and determines the duration between two specific times. It manages standard sexagesimal (base-sixty) math, ensuring that sixty seconds correctly carry over to one minute, and sixty minutes carry over to one hour. Professionals tracking billable hours, project managers scheduling tasks, and students solving duration problems use this tool to avoid manual calculation errors.
