The rules are:

Overtime (1.5 times rate of pay) is paid for:

• Any time worked in excess of 8 and up to and including 12 hours per day.

• The first 8 hours worked on the seventh consecutive day of work in the work week.

Double time (2 times rate of pay) is paid for:

• Any time worked in excess of 12 hours in one day.

• Any time in excess of 8 hours on the seventh consecutive day of work in the work week.

Under California law, a workweek is any seven consecutive days, starting with the same calendar day each week beginning at any hour on any day, so long as it is fixed and regularly occurring. A workweek is a fixed and regularly recurring period of 168 hours, or seven consecutive 24-hour periods. An employer may establish different workweeks for different employees, but once an employee’s workweek is established, it remains fixed regardless of his or her working schedule. An employee’s workweek may be changed only if the change is intended to be permanent and is not designed to evade the employer’s overtime obligation.
