Overtime and days per week for 8 AM to 4:30 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.

|---|---|---|---|---|
| 3 days a week | 24 | 24 | 0 | 24 |
| 4 days a week | 32 | 32 | 0 | 32 |
| 5 days a week | 40 | 40 | 0 | 40 |
| 6 days a week | 48 | 40 | 8 | 52 |
