Calendar week

A calendar week is a seven-day period that runs from Sunday through Saturday, based on the standard calendar format used in the United States. Unlike a rolling 7-day period or custom workweek, a calendar week resets every Sunday and ends every Saturday—regardless of your company’s operating hours.

For small business owners, understanding the calendar week is useful for tracking employee hours, calculating overtime, and aligning with federal and state wage and hour laws. 

While the calendar week is not used as a legal reference period for labor laws, it can be an easy way to structure your business for items such as:

Even if your business operates on a different schedule (e.g., Monday to Sunday or rotating shifts), your employees may use the calendar week as a reference for their workload. Just make sure you follow your defined workweek for labor rules like overtime work.

While they may seem similar, calendar week and workweek are not the same thing:

Employers are allowed to define their own workweek (e.g., Wednesday to Tuesday), but some states and local agencies still use the calendar week when enforcing labor laws or scheduling protections.

Under federal law (FLSA), non-exempt hourly employees must be paid overtime—typically 1.5 times their regular pay rate—for any hours worked over 40 in a single workweek. While employers can define their own 7-day workweek, some businesses find it easier to use the calendar week.

If you specify your workweek to be the calendar week, and an employee works:

They’ve worked 43 hours during the calendar week (Sunday–Saturday) and are owed 3 hours of overtime.

Using the calendar week structure helps streamline:

If your business runs variable shifts, restaurants, or retail, organizing your schedule and reports by calendar week can simplify operations.
