Average Work Days Per Month
On average, you’re looking at about 20 to 22 work days per month in the US. This estimate comes from analyzing a full year, where 2025 has 250 work days after excluding weekends and federal holidays, out of 365 total days. This average helps with quick planning, but for precise counts, you’ll need to check specific months.
Why It Matters
Knowing the number of work days in a month is key for several reasons. It helps with payroll, ensuring accurate pay for hourly workers or salaried employees. It’s also vital for project planning, allowing you to set realistic deadlines. Plus, it benefits work-life balance by helping you plan personal time around work commitments.
How to Calculate Work Days
You can calculate work days with a simple formula: Total Days – Weekends – Federal Holidays. For example, in January 2025:
- Total days: 31
- Weekends: 8 (4 Saturdays, 4 Sundays)
- Federal holidays: 2 (New Year’s Day, Martin Luther King Jr. Day)
- Work Days: 31 – 8 – 2 = 21
Tools like the Business Days Calculator can automate this process, saving you time.
Standard Number of Working Days in a Month
The average number of work days per month in the US is approximately 20 to 22, based on a standard five-day workweek, excluding weekends and federal holidays. This average is derived from the total work days in a year, which for 2025 is 250 work days.
These 250 days come from subtracting 104 weekend days (52 Saturdays and 52 Sundays) and 11 federal holidays from the 365 total days in 2025. For payroll and work days calculation, this average provides a useful baseline, but exact counts require month-specific analysis due to holiday variations.
Monthly Work Days Calendar for 2025
The number of work days in a month fluctuates due to the calendar and federal holidays. Below is a table detailing the number of work days (business days excluding weekends and holidays) for each month in 2025, based on data from LeaveBoard:
| Month | Total Days | Weekdays | Federal Holidays on Weekdays | Work Days | Notes |
|---|---|---|---|---|---|
| January | 31 | 23 | 2 (New Year’s, MLK Day) | 21 | New Year’s (Wed), MLK Day (Mon) |
| February | 28 | 20 | 1 (Presidents’ Day) | 19 | Presidents’ Day (Mon) |
| March | 31 | 21 | 0 | 21 | No federal holidays |
| April | 30 | 22 | 0 | 22 | No federal holidays |
| May | 31 | 22 | 1 (Memorial Day) | 21 | Memorial Day (Mon) |
| June | 30 | 21 | 1 (Juneteenth) | 20 | Juneteenth (Thu) |
| July | 31 | 23 | 1 (Independence Day) | 22 | Independence Day (Fri) |
| August | 31 | 22 | 0 | 21 | No federal holidays |
| September | 30 | 22 | 1 (Labor Day) | 21 | Labor Day (Mon) |

| November | 30 | 20 | 2 (Veterans Day, Thanksgiving) | 18 | Veterans Day (Tue), Thanksgiving (Thu) |
| December | 31 | 23 | 1 (Christmas) | 22 | Christmas (Thu) |
| Total | 365 | 262 | 11 | 250 | – |
This table shows that months like November (18 work days) have fewer work days due to multiple holidays, while April and October (22 work days) have more due to no holidays.
Variations by Month
The number of work days varies monthly due to several factors:
- Total Days: February has 28 days, reducing the potential weekdays compared to March’s 31.
- Weekends: Months with five weekends (e.g., January 2025) have fewer weekdays than those with four.
- Federal Holidays: Holidays like Thanksgiving (Thursday, November 27, 2025) reduce work days when they fall on weekdays. In 2025, all 11 federal holidays fall on weekdays, directly impacting the count.
For example, work days in January 2025 are 21 because New Year’s Day (Wednesday) and Martin Luther King Jr. Day (Monday) reduce the 23 weekdays by two. In contrast, April 2025 has 22 work days with no holidays.
Impact of Federal Holidays
Federal holidays significantly affect the number of work days, excluding weekends and holidays. The US observes 11 federal holidays in 2025, all on weekdays:
- New Year’s Day: January 1 (Wednesday)
- Martin Luther King Jr. Day: January 20 (Monday)
- Presidents’ Day: February 17 (Monday)
- Memorial Day: May 26 (Monday)
- Juneteenth: June 19 (Thursday)
- Independence Day: July 4 (Friday)
- Labor Day: September 1 (Monday)
- Columbus Day: October 13 (Monday)
- Veterans Day: November 11 (Tuesday)
- Thanksgiving Day: November 27 (Thursday)
- Christmas Day: December 25 (Thursday)
These holidays reduce work days when they fall on weekdays, as most businesses close. For instance, November 2025 has only 18 work days due to Veterans Day and Thanksgiving. Some state-specific holidays, like Patriots’ Day in Massachusetts, may further reduce work days locally.
How to Calculate Work Days
Calculating the number of work days in a month is straightforward with the formula: Total Days – Weekends – Federal Holidays. Here’s an example for work days in January 2025:
- Total days: 31
- Weekends: 8 (4 Saturdays, 4 Sundays, e.g., January 4-5, 11-12, 18-19, 25-26)
- Federal holidays: 2 (New Year’s Day on Wednesday, MLK Day on Monday)
- Work Days: 31 – 8 – 2 = 21
This method ensures accuracy for payroll and work days calculations. For instance, an hourly worker in January 2025 working 8 hours per day would log 168 hours (21 × 8). This calculation can be applied to any month by adjusting for the specific number of days and holidays.
Tools and Calculators
Manual calculations can be time-consuming, especially for long periods or complex schedules. Online tools simplify the process:
- Business Days Calculator from Time and Date allows users to input start and end dates, automatically excluding weekends and US federal holidays.
- LeaveBoard offers a downloadable Excel file with a 2025 calendar detailing work days and hours per month, ideal for HR professionals and project managers.
These tools are user-friendly for beginners and efficient for pros, supporting tasks like payroll, scheduling, and project planning. They also allow customization for state-specific holidays if needed.
Practical Applications
Understanding the number of work days in a month has several practical uses:
- Payroll: Accurate work day counts ensure correct payments. For example, an hourly worker in May 2025 (21 work days) at 8 hours per day works 168 hours, critical for payroll accuracy.
- Project Planning: Managers can set realistic timelines. A project requiring 40 work days in June 2025 (20 work days) would need two months.
- Scheduling: Businesses can allocate shifts or resources, especially in industries like retail, where weekends may count as work days.
- Work-Life Balance: Planning work days helps carve out personal time, reducing burnout.
For career management, tracking work days can be part of maintaining professional growth, similar to routine career check-ins.
Current Job Market Context
In 2025, the US job market emphasizes flexibility and work-life balance, influencing how work days are perceived. Hybrid and remote roles are increasingly popular, with 63% of professionals preferring flexible schedules, according to work-life balance statistics.
This trend makes accurate work day calculations vital for aligning work schedules with personal life, especially for job seekers targeting roles with a strong balance. Industries like tech and healthcare lead in offering flexibility, while traditional sectors like retail may include weekends, affecting work day counts.
International Differences
Work days vary globally due to different holiday schedules and weekend structures. For example:
- United Kingdom: Approximately 253-256 work days annually, with eight bank holidays in England and Wales.
- European Union: Averages around 257 work days, varying by country due to holidays like Bastille Day in France.
- Asia: Highly variable due to cultural holidays like Lunar New Year, reducing work days significantly in some months.
Weekend structures also differ, with some Middle Eastern countries observing Friday-Saturday weekends, altering work day counts. These differences are crucial for US professionals working with global teams or considering international opportunities.
Leap Years and Other Factors
Leap years add an extra day to February (29 days), potentially increasing work days if it’s a weekday. However, 2025 is not a leap year, so February has 19 working days. Other factors include:
- Part-Time Work: Reduces individual work days but doesn’t affect monthly totals for planning.
- Industry Variations: Retail or hospitality may include weekends as work days, increasing counts for those workers.
- Remote Work: Flexible schedules may blur work day definitions, but standard calculations apply.
Conclusion
The average number of work days in a month in the US is 20 to 22, but this varies by month, holidays, and the calendar. In 2025, the US has 250 work days, with months like November (18 work days) and April (22 work days) showing significant variation.
