In the United States, full-time employees typically work 160–176 hours per month, calculated from a 40-hour week or 8-hour days across 20–22 workdays. Holidays and weekends cause variations, with some months totaling up to 184 hours (23 days). For IRS and benefits calculations, a lower threshold like 130 hours per month may be used.

Work hours per month differ based on part-time, flexible, and shift schedules. A 20-hour weekly part-time job translates to approximately 80–88 hours in a month of four to four-and-a-third weeks. A standard 40-hour full-time job adds up to about 160–173 hours per month, with the exact total depending on the length of the month.

The number of workdays differs each month because some months have more days than others. Weekends are generally non-working days, but some regions observe different schedules, like a Sunday-only weekend. Public holidays also vary by country or region, which influences the total working days per month.
