California SB 464 'Weeks Worked' Calculation Guide: Step-by-Step for HR Managers
California Senate Bill 464 (SB 464) introduces strict reporting guidelines for employers. Among the most complex additions is the mandatory calculation of "Weeks Worked" for every employee on the payroll roster.
What is SB 464 and Why Does It Mandate 'Weeks Worked'?
Under California's updated Pay Data Reporting requirements, the Civil Rights Department (CRD) requires companies with 100 or more employees to submit annual wage and hour audits. SB 464 closes loopholes by requiring employers to report the exact number of weeks each employee worked during the reporting year.
This metric is crucial because it helps state regulators identify pay disparities by normalizing compensation against the actual length of employment, preventing part-time or partial-year employees from distorting wage statistics.
Step-by-Step Calculation Methodology
Calculating weeks worked seems simple initially, but payroll cycles (semi-monthly, bi-weekly, weekly) complicate the math. Here is the legally compliant calculation standard:
The Standard Formula:
Weeks Worked = (Total Days Employed in Calendar Year / 7) rounded up to the nearest whole week.
1. Defining the Employment Window
For each employee, compute the number of calendar days between their hire date (or January 1st if hired earlier) and their termination date (or December 31st if still active).
2. Factoring in Unpaid Leaves of Absence
Any week where the employee was on a continuous unpaid leave of absence for 7 consecutive days must be subtracted from the total. Paid leaves (e.g. PTO, sick leave, paid family leave) count as weeks worked.
3. Standardizing Payroll Data
If you pay bi-weekly, you cannot simply assign 2 weeks to every pay period. An employee starting mid-period may have only worked 3 days. Use the actual days worked to determine partial-period compliance.
Example Walkthrough
| Employee Scenario | Dates | Calculation | Result |
|---|---|---|---|
| Full-Year Active | Jan 1 – Dec 31 | 365 days / 7 = 52.14 | 52 Weeks |
| Mid-Year Hire | Hired June 1 – Dec 31 | 214 days / 7 = 30.57 | 31 Weeks |
| Unpaid FMLA Leave | Full year (4 weeks unpaid FMLA) | 52 weeks - 4 weeks leave | 48 Weeks |
