California Code, Labor Code - LAB § 204

(a) All wages, other than those mentioned in Section 201, 201.3, 202, 204.1, or 204.2, earned by any person in any employment are due and payable twice during each calendar month, on days designated in advance by the employer as the regular paydays. Labor performed between the 1st and 15th days, inclusive, of any calendar month shall be paid for between the 16th and the 26th day of the month during which the labor was performed, and labor performed between the 16th and the last day, inclusive, of any calendar month, shall be paid for between the 1st and 10th day of the following month. However, salaries of executive, administrative, and professional employees of employers covered by the Fair Labor Standards Act, as set forth pursuant to Section 13(a)(1) of the Fair Labor Standards Act, as amended through March 1, 1969, in Part 541 of Title 29 of the Code of Federal Regulations, as that part now reads or may be amended to read at any time hereafter, may be paid once a month on or before the 26th day of the month during which the labor was performed if the entire month's salaries, including the unearned portion between the date of payment and the last day of the month, are paid at that time.

(c) However, when employees are covered by a collective bargaining agreement that provides different pay arrangements, those arrangements shall apply to the covered employees.

(d) The requirements of this section shall be deemed satisfied by the payment of wages for weekly, biweekly, or semimonthly payroll if the wages are paid not more than seven calendar days following the close of the payroll period.

(e) Notwithstanding subdivision (a) of Section 220, all wages earned by employees directly employed by the Regents of the University of California shall be paid on a regular payday. For the employees on a monthly payment schedule, payment is due no later than five days after the close of the monthly payroll period. For employees on a more frequent payment schedule, payment is due according to the pay schedule announced by the University of California in advance. Nothing in this section shall be construed to prohibit the Regents of the University of California from allowing its employees to choose to distribute their pay so that they will receive paychecks throughout the year, rather than during pay periods worked only.
