CalcHoursHow 9:30 AM to 3:30 PM is calculated
3:30 PM minus 9:30 AM is 6 hours of presence. The half hour is the only part people trip over: count the minutes to the next full hour first, then the full hours, then whatever is left. In 24-hour time it is 09:30 to 15:30, which makes the subtraction plain. Unpaid breaks are deducted from that. Federal law does not require a break; with a common 30-minute lunch you are paid for 5:30 hours (5.50 decimal hours).
| Unpaid break | Hours worked | Decimal |
|---|---|---|
| 0 min | 6:00 | 6.00 |
| 15 min | 5:45 | 5.75 |
| 30 min | 5:30 | 5.50 |
| 45 min | 5:15 | 5.25 |
| 60 min | 5:00 | 5.00 |
Per week and per month
Five days from 9:30 AM to 3:30 PM with a 30-minute lunch add up to 27:30 hours per week (27.50 h) and about 119.08 hours per month (factor 4.33). That stays under the 40-hour FLSA overtime threshold. Enter your own breaks, blocks and pay rate in the calculator above; the Week tab totals the days and splits overtime.
