How it works

• Enter times as 1.30/1:30 (1h 30min) or 1.30.45/1:30:45 (with seconds).
• Use + − * / to add, subtract, multiply or divide values.
• Group calculations with ( ) to control order of operations.
• Reference any previous line with #1, #2, etc. to reuse its result.
• The total at the bottom sums up all time values across all lines.
