Tentang Time Calculator
Adding times on paper goes wrong fast: 40 minutes plus 35 minutes is not 75 minutes. This calculator performs base-60 arithmetic for you — stack multiple HH:MM:SS durations and add them, or subtract one from another, with clean carrying between units. It totals work sessions for timesheets, running splits for training plans, and clip lengths for video editing, and shows both the total and a breakdown per entry.
Cara memakai Time Calculator
- Enter each duration on its own line, like 1:30:00.
