Formula and Assumptions

Elapsed minutes = end - start - break; overnight shifts add 24 hours before subtracting.

If the end time is earlier than the start time, the calculator treats it as an overnight span.

Rounding is applied after subtracting the break.

Reference Upgrade

Built from the Calculator.net model, with added context.

Live validation and instant result updates instead of a submit-only workflow.

Multiple decision metrics are shown together, not only the primary answer.

Formula notes and assumptions are visible on the page so the math is easier to audit.

Reference Model

Modeled after the input style and primary output on Calculator.net's Time Calculator.

The page keeps the math in one place and exposes the assumptions beside the result.

Default inputs: startTime=09:00, endTime=17:30, breakMinutes=30, roundTo=1
