It also handles clock-outs that cross midnight (a 22:00 - 06:00 shift counts as 8 hours, not -16) and accepts fractional hours like 7.5. Pair it with the Work Week Calculator for a fuller plan.

Frequently asked questions
What if a shift crosses midnight?
Type the times in order (e.g. "22-06"); the calculator adds 24 hours to the end automatically.
How are breaks subtracted?
Use "(45m break)" or "(1h break)" anywhere in the line to subtract that amount from the day total.
