How Many Work Hours in a Month? 2025 Guide + Detailed FAQs

Ever caught yourself staring at the calendar, wondering how many work hours in a month actually exist? If you manage technicians, handle payroll, or schedule jobs across multiple zip codes, that number matters more than you'd think. The year 2025 is no exception.

Time, after all, is money. And in field service, it’s also planning, payroll, overtime, and productivity.

Miscalculate those work hours in a month, and you might find yourself overbooked, understaffed, or over budget.

Here’s the deal: the total working hours per month don’t stay fixed. They shift depending on how the weekdays and holidays fall. That means no two months play out exactly the same on a schedule or spreadsheet.

In this guide, we’re going to look at how many hours in a work month you can count on for 2025, why the number isn’t always predictable, and how Field Promax makes tracking everything a lot less painful thanks to its Time Card & GPS Tracking feature.

Here’s the straightforward answer: June 2025 gives you 21 working days, assuming a standard Monday through Friday week and no federal holidays. Multiply that by 8 hours per day, and you land on 168 hours for the month.

That’s your number. If your team’s full-time, on a 40-hour workweek, this is what they’ll be scheduled for, give or take some vacation time or job site delays.

Note: If your team observes Juneteenth (June 19) as a federal holiday, subtract one day (8 hours) from the total. That brings the monthly total to 160 working hours.

But don’t get too cozy with that total. It doesn’t always look like this.

Monthly hours shift more than you'd expect. Here’s why:

• Weekday count varies: Some months have 20 workdays; others go up to 23.

• Holidays interfere: Toss in a federal day off, and you’re shaving off 8 hours right there.

• The calendar’s messy: Leap years, month lengths, and weekday starts throw things off.

So when someone asks, “how many hours per month do people usually work?” there’s no one-size-fits-all number. It changes month to month, and that’s exactly why businesses track it closely.

Most of the time, you're looking at somewhere between 160 and 184 hours per month for a full-time schedule. That’s the general range for average working hours in a month if you're operating on 8-hour days.

If you're just trying to set a general benchmark for planning or payroll, here’s a quick formula that employers often use: (40 hours per week × 52 weeks) ÷ 12 months = 173.33 hours

That’s what many HR and payroll systems use when they need a standard monthly number, especially for salaried roles. It's close enough for averages, but don't rely on it for billing or scheduling because real-life months aren’t that neat.

Let’s take a closer look at August 2025. Here’s the month at a glance:

• Total calendar days: 31
• Workdays (Mon–Fri): 23
• Federal holidays: 0
• Total work hours: 23 × 8 = 184 hours

With no holidays and a full five-week run, August 2025 is one of the most workload-heavy months on the calendar. If you're managing field teams or planning overtime limits, this month delivers more billable time than most but also demands sharper scheduling to avoid burnout.

You don’t need fancy software to figure this out (though, we won’t say no to that). Here’s the manual way:

1. Count the number of weekdays in the month
2. Subtract any official holidays
3. Multiply the result by your standard daily hours (usually 8)

21 workdays × 8 hours = 168 hours

Simple, but critical. If you're budgeting labor hours, projecting revenue, or keeping an eye on overtime thresholds, this number guides your decisions.

Heads-up: If your company observes Juneteenth (June 19) as a holiday, you'll need to subtract one workday. That brings the total down to 160 hours for the month.

Field service teams aren’t just fighting the clock anymore; they're managing it. And in 2025, your competition is probably using some form of automation or mobile tracking. If you’re still relying on gut estimates or messy time sheets, you're already behind.

Accurate hour tracking helps you:

• Avoid payroll errors
• Prevent overtime surprises
• Improve job costing
• Plan shifts without chaos

Digital tools like Time Card & GPS Tracking make this painless. Your techs clock in through their mobile app. Their location and job hours sync instantly. No phone tag. No paper trails. Just time data you can trust.

You don’t need to micromanage every minute. Just make sure the right ones are recorded. That’s what separates smart ops from stressed-out ones.

If you’re managing HVAC, plumbing, electrical, or general maintenance crews, those 8-hour chunks of time add up fast.

You’re balancing:

• Billable vs. non-billable time
• Travel hours vs. work hours
• Overtime triggers
• Part-time vs. full-time allocations

Knowing how many working hours in a month lets you forecast labor costs, plan service schedules, and set proper customer expectations.

And when your field data syncs in real-time, you can make decisions without waiting until the end of the month or the next staff meeting.

Whether you’re running payments, approving overtime, or just trying to understand where your team's hours go each month, knowing how many work hours are in a month can give you back control.

Use it to forecast, plan, and adjust staffing, all without doing mental gymnastics. Better yet, let Field Promax handle it for you.

Give it a try. It’ll probably save you a dozen spreadsheets.
