Working with Base-60 Math

How the Tool Calculates

To guarantee mathematical accuracy, this calculator first converts all input values (hours, minutes, seconds) into a flat "total seconds" integer. It performs standard base-10 arithmetic on that integer, and then uses modulo division to convert the final total back into human-readable hours, minutes, and seconds.
