Какво е времетраене?

Time duration is the amount of time that passes between two points in time, or the length of time something takes. This calculator finds duration between two clock times, adds or subtracts duration from a time, converts between time units, and computes end time from a start time and elapsed duration.

Time format: HH:MM or HH:MM:SS (24-hour)

Формат на времето

HH:MM: Часове: минути (напр. 14:30)

HH:MM:SS: Часове:Минути:Секунди (напр. 14:30:45)

Use 24-hour format (0-23 hours).
