How this calculator works
This general-purpose time calculator adds two durations together, each entered in hours, minutes, and seconds, useful for combining work shifts, workout segments, cooking steps, or any other time spans you need to total up.
Both durations are converted into total seconds, added together, and then converted back into a readable hours:minutes:seconds format, along with the grand total in minutes and seconds for reference.
This is a simple arithmetic tool for general everyday time tracking.
