A workweek is a fixed, recurring period of seven consecutive days used to measure an employee’s working time. Under the federal Fair Labor Standards Act (FLSA), it consists of 168 consecutive hours. The period can begin on any day and at any hour, so it does not have to match a calendar week or a Monday-to-Friday schedule. Employers use this defined period to apply federal overtime rules to covered, nonexempt employees. A workweek is different from a work schedule, which sets when someone is expected to work, and from a pay period, which sets the dates included in a paycheck. These periods can have different start and end dates. That distinction remains important when a worker’s schedule changes or payroll is processed every two weeks.

How Is a Workweek Established?
For FLSA purposes, an employer establishes a fixed and regularly recurring period of 168 hours. It may begin at a particular day and time, such as Monday at midnight or Sunday at 6 a.m. Different workweeks may apply to different employee groups. Once established, the start time remains the boundary for measuring hours even if employees work different days or shifts.
The workweek is a timekeeping boundary rather than a description of a typical work pattern. A worker might have shifts that cross midnight or work different days from one week to the next. Those changes do not by themselves reset the defined period. Federal rules permit an employer to change a workweek when the change is intended to be permanent and is not designed to avoid overtime obligations. A temporary change in scheduling is not the same as changing the established workweek. For the federal definition and its application, see the Department of Labor’s FLSA guidance.
Keeping the start and end boundaries clear helps ensure that hours are counted in the correct period. Employers should communicate the established workweek to the people responsible for recording and reviewing time. Workers should also know which boundary applies so they can check that their reported hours fall in the right week.
How Does a Workweek Affect Overtime?
Under the federal FLSA, covered employees who are not exempt generally must receive overtime pay for hours worked over 40 in a workweek. The required federal rate is at least one and one-half times the employee’s regular rate. The calculation is made separately for each workweek. An employer generally cannot average hours across two workweeks to cancel overtime in one of them. The Department of Labor explains the federal rule on its page about overtime.
For example, if a nonexempt employee works 45 hours in one workweek and 35 in the next, the first week still has five hours above the federal threshold. The shorter following week does not erase those hours. This example describes the federal rule for covered, nonexempt employees. Whether a particular worker is covered or exempt can depend on the work performed and other legal requirements.
State or local laws may provide different or more protective requirements. Employers may need to follow the rule that applies to the worker’s situation. The FLSA is a federal law and does not replace checking applicable state and local rules. A worker’s classification and the details of the work can affect which overtime requirements apply. Accurate records of hours worked are important because the calculation depends on the hours within each defined workweek.
How Is a Workweek Different from a Schedule or Pay Period?
A workweek measures time for purposes such as federal overtime calculations. A work schedule identifies when a person is expected to work. A pay period identifies the dates included in a payroll cycle. Each term answers a different practical question. Their boundaries do not have to line up, and one does not automatically determine the other.
Suppose an employer’s workweek runs from Monday through Sunday. A worker may be scheduled Tuesday through Saturday while the employer issues pay every two weeks. The biweekly pay period contains two separate workweeks for federal overtime calculations. Paying every two weeks does not turn the workweek into a 14-day period. Similarly, a work schedule that changes from week to week does not itself change the employer’s established workweek.
Accurate payroll depends on recording work time against the correct workweek even when a paycheck covers a longer span. The U.S. Department of Labor states that hours cannot be averaged across workweeks to determine federal overtime. Separating these concepts helps workers understand why a paycheck may cover multiple workweeks while overtime is calculated week by week.
Does the Workweek Dictate Which Days or Hours Someone Works?
No. The workweek sets the recurring period for measuring hours; it does not require employees to work five days or follow a standard daytime schedule. A person might work four longer shifts, part-time hours, rotating shifts or overnight shifts. Those arrangements can still be measured within the same defined seven-day period. A flexible working arrangement may change when work happens without changing the workweek’s fixed start.
Nor does a workweek automatically mean that someone has a 40-hour schedule. Forty hours is the federal overtime threshold for covered, nonexempt employees, not a requirement that everyone work that amount. An organization may define full-time hours differently for its own scheduling or benefits purposes, subject to applicable law and plan terms. The workweek remains relevant even if someone works fewer hours or has a variable schedule.
For overnight shifts, hours should be assigned to the workweek in which they are worked under the established boundaries. A shift that crosses the start of a new workweek may therefore have hours in two different workweeks. The schedule itself does not alter where that boundary falls. Clear time records help distinguish the hours worked from the scheduled shift as a whole.
Why Does the Workweek Matter for Contingent Workforce Programs?
For organizations using contingent workers, a clearly defined workweek helps align time records with the period used to review hours and calculate pay. It matters when a worker changes shifts or works at more than one location. It can also matter when time is submitted through different project teams. The timekeeping process should capture actual hours and assign them to the right workweek. An assignment plan alone may not show when work was performed.
In contingent workforce management, an organization and its workforce partners may have separate roles in scheduling, collecting time and processing payment. Those roles should be clear enough that hours reach the responsible payroll process promptly. Hours should not be moved between workweeks simply because the pay cycle differs. Consistent procedures can help identify discrepancies between time records and scheduled hours before payroll is processed.
The FLSA’s workweek rules apply based on the worker’s legal circumstances and the relevant employment relationship. Understanding whether someone is an employee and who is responsible for timekeeping and payroll helps organizations manage the process. This prevents an assignment schedule from being confused with the legal overtime calculation period. For contingent workforce programs, the practical value of a clear workweek is that time reporting and payroll review can use the same defined boundary.
