How it’s worked out
On a 24-hour clock 9 AM is 9:00 and 9 PM is 21:00. 21:00 − 9:00 = 12:00. Take off any unpaid break, then divide leftover minutes by 60 for decimal hours.
A single 12-hour day is not overtime under federal law, which counts only hours over 40 in a workweek. In California, Alaska and (for lower-paid workers) Nevada, paid hours over 8 in a day earn 1.5×; see overtime rules by state.
