Time Rounding Rules
The Department of Labor permits rounding to the nearest increment if it doesn't consistently favor the employer. Common increments:
- 6 minutes (1/10 hour): 8:07 AM rounds to 8:06, 8:09 rounds to 8:12
- 15 minutes (1/4 hour): 8:07 AM rounds to 8:00, 8:08 rounds to 8:15
- 30 minutes (1/2 hour): Less common, largest increment the DOL generally allows

| California | After 8 hrs | After 40 hrs | Double time after 12 hrs/day or 8 hrs on 7th consecutive day |

| Colorado | After 12 hrs | After 40 hrs | Also OT after 12 consecutive hours |
| Nevada | After 8 hrs | After 40 hrs | Daily OT if rate is under 1.5x minimum wage |
Break Requirements
Federal law doesn't require breaks, but most states do:
- Meal breaks: Most states require a 30-minute unpaid meal break after 5-6 hours of work
- Rest breaks: Many states require a paid 10-minute break per 4 hours worked
- Minors: Stricter break requirements apply to workers under 18
Converting Time to Decimal
Payroll systems use decimal hours. Divide minutes by 60:
| Minutes | Decimal | Minutes | Decimal |
|---|---|---|---|
| 5 min | 0.08 | 35 min | 0.58 |
| 10 min | 0.17 | 40 min | 0.67 |
| 15 min | 0.25 | 45 min | 0.75 |
| 20 min | 0.33 | 50 min | 0.83 |
| 25 min | 0.42 | 55 min | 0.92 |
| 30 min | 0.50 | 60 min | 1.00 |
