About Time Calculation
Calculating time differences can be tricky due to the base-60 system (60 minutes in an hour) and the 12/24-hour cycles. This tool simplifies the math, ensuring you get accurate durations or future timestamps without manual conversion errors. It's especially useful for payroll, travel planning, and shift management.
