Day 1 is the first day of your workweek. California counts overtime by the day, so it needs each day.
- Regular 40 h
- Overtime 1.5x 6 h
- Regular pay40 h x $22.00$880.00
- Overtime pay6 h x $33.00 (1.5x)$198.00
- Total pay$1,078.00
overtime h = 46 - 40 = 6
regular = 40 x 22 = 880.00
overtime = 6 x 22 x 1.5 = 198.00
total = 1,078.00US federal law (FLSA): non-exempt employees get at least 1.5 times their regular rate for every hour over 40 in a workweek. There is no federal daily, weekend or holiday overtime, and weeks cannot be averaged. Some states add daily rules.

Overtime questions
Is overtime paid after 8 hours in a day?
Not under federal law, which only counts hours over 40 in the workweek. California pays overtime after 8 hours in a workday, and some other states have daily rules of their own.
Is double time required by law?
Not by federal law. California requires double time for hours over 12 in a workday and for hours over 8 on the 7th consecutive day worked in the workweek.
Do UK employers have to pay extra for overtime?
No. GOV.UK says employers do not have to pay for overtime, and your contract sets the rate. Your average pay for all the hours you work must still be at least the National Minimum Wage.
Can overtime be averaged over two weeks in the US?
No. Under the FLSA each workweek stands alone, and averaging hours over two or more weeks is not allowed.
