You are at work for 7:30 (7.5 hours) each day and paid for 7:00 (7 hours) once the 30-minute unpaid break is taken off. Multiply by the days you work to get the longer periods below.

Overtime and days per week for 8:30 AM to 4 PM
Overtime here means weekly paid hours above 40, with a 1.5 times multiplier shown as pay-equivalent hours. Your contract or local law may define overtime differently, for example by day. At five days you do not reach the 40-hour threshold, so there is no overtime until you add days or hours.
| Days worked | Paid hours | Regular (up to 40) | Overtime (over 40) | Pay-equivalent hours at 1.5x |
|---|---|---|---|---|
| 3 days a week | 21 | 21 | 0 | 21 |
| 4 days a week | 28 | 28 | 0 | 28 |
| 5 days a week | 35 | 35 | 0 | 35 |
| 6 days a week | 42 | 40 | 2 | 43 |
| 7 days a week | 49 | 40 | 9 | 53.5 |
