How Time Addition Works
When adding time, the calculator converts all time values to minutes, performs the addition, then converts back to your preferred format. This ensures accurate calculations across different units.
Using Negative Values
Negative time inputs allow you to subtract time from your total. This is useful for time budgeting and checking if you can complete tasks within a given timeframe.
