“Working 9 to 5, what a way to make a living,” as the famous song by music legend Dolly Parton goes. But have you ever wondered why the 9 to 5 schedule became so popular? Is it the most effective way of working? Or are you and your team working too much? Join us and find out all you need to know about average working hours throughout history.
Today vs. 100 Years Ago: How Many Work Hours in a Year?
Back in hunter-gatherer societies, the average working day was around three to five hours (but up to eight if you include food prep). And that’s just as well, as the average lifespan at the time was between 21 and 37 years.
Since then, a lot has changed. Lifestyles have shifted, and we’ve become a more modern society. And that seems to mean working more. But why? And is it effective? For starters, let’s take a look at how working life has changed throughout history.
❗ To navigate this evolving landscape, using the best time tracking software can help ensure you and your team maintain a balanced workload.

What are the average hours worked per week?
Nowadays, according to US labor law, a full-time workweek equals 40 hours. Multiplied by 52 weeks, that’s 2,080 hours per year. But most people don’t actually work that much.
- Global average: Around 35 hours/week, or 1,820 hours/year
- Monthly average: About 176 hours
- Part-time or statutory employees may work even less
Working hours have changed over time due to historical and economic factors. Let’s take a look at how working hours evolved over the last 70 years:

- 1914 (WWI): Average was 55 hours/week, with some workers doing 72 hours to meet wartime demands
- But productivity declined beyond 40 hours/week (source)
- 1926: Henry Ford introduced the 9-to-5, 40-hour week
- 1930s: During the Great Depression, many still worked 46–50 hours/week
- Post-WWII: The 40-hour week became standard
- Today, employers are exploring new models like the 9/80 schedule and 4-day workweeks
What Is the Average Working Year?
It might seem that the work never ends, but how much are we really working? Let’s take a look at the average working year as it stands today.
Number of hours in a year vs. how many you spend working
It might feel like work takes up most of your life. But how does it compare to the total number of hours in a year? Here’s a quick breakdown:

And don’t forget about leap years! Every four years, February gains an extra day—adding 24 hours and bringing the total to 8,784 hours.
If you worked the global average of 1,820 hours in 2023, then about 20.78% of your entire year was spent working. That’s nearly one-fifth of your time.
How many full-time hours per year are there?
To calculate your annual work hours, you need to consider:
- Holidays
- Vacations
- Paid time off
Let’s say you had 12 vacation days and 8 paid days off last year. That’s 20 days or 160 hours off (20 × 8). Subtract that from 2,080 (the standard full-time hours), and you worked 1,920 hours in total.

Work hours in a year: North America, Europe, and Asia
Work hours differ greatly depending on where you are. Here’s a snapshot:
Country with the longest working hours: 🇲🇽 Mexico – 2,137 hours/year
Country with the shortest working hours: 🇩🇰 Denmark – 1,380 hours/year
But here’s the twist: Danes earn $55 more per hour than Mexicans, showing that longer hours don’t equal higher productivity.

How many hours did Everhour users work last year?
Everhour users are a productive bunch. It’s a fact! But have you ever wondered about the average work hours in a year logged by Everhour users? Wonder no more! Here’s just how productive we’ve been together. *

How many workweeks are there in a year?
There are 52 weeks in a year, but no one works all of them. Once you factor in weekends and holidays, that number drops.
To estimate how many weeks you actually work:
- Subtract holidays and weekends
- Divide the result by 7 (days per week)

But the question here isn’t always how many hours or weeks are worked in total. It’s also if an employee is receiving holiday pay. Normally, such holiday payments are included in contracts, so employees know if they are entitled to paid time off.
In the US, employers are not always required to compensate workers if federal holidays fall on a weekend. However, some companies choose to do so to gain loyalty and boost morale.
How many weeks in a year overall vs time spent working?

The International Organization for Standardization states that a year is 52 weeks. But if we want to get technical about it, it’s a little more than that. If you multiply 52 weeks by 7 days, you’ll get 364 days. But there are 365 days in a year, right? Correct!
That’s why there are 52.143 weeks in a year, or 52 weeks and one day. In a leap year, that becomes 52.286 weeks in a year or 52 weeks and two days. So:
1 Year = 52 weeks and 1 day
1 Leap Year = 52 weeks and 2 days
Now, how does this compare to time spent working? Let’s take a look at the weeks spent working by country:

Now, who is picking up their French textbook and booking a ticket?!
What do workweeks in a year look like worldwide? Fast facts!
Think it’s Monday to Friday everywhere? Think again. Workweeks vary around the world. Check out these fast facts:
- In many Muslim-majority countries, the workweek runs from Sunday to Thursday
- Mexico, Singapore, and Thailand (among others) have 6-day workweeks
- New Zealand and some Asian countries are trialing a 4-day workweek
- In Russia, Belarus, and other former Soviet Union countries, subbotniks (working Saturdays) are scattered throughout the year—citizens perform voluntary, unpaid work
How many workweeks in a year in North America, Europe & Asia?
In theory, all 52 weeks of the year are available for work—but most people don’t work all of them. The average number of workweeks per year is around 36.3.
To calculate how many weeks you actually work, subtract holidays and weekends, then divide the remaining days by 7.
- UK: 256 working days = 36.6 workweeks
- US: 261 working days = 37.3 workweeks
- Denmark: 254 working days = 36.3 workweeks
- Australia: 254 working days = 36.3 workweeks
- Ireland: 252 working days = 36 workweeks
- Russia: 249 working days = 35.6 workweeks
- France: 212 working days = 30.3 workweeks
- South Africa: 249 working days = 35.6 workweeks
But it’s not just about how many weeks or hours are worked—it’s also about whether those holidays are paid. Typically, employment contracts spell this out.
In the US, employers aren’t required to compensate workers when federal holidays fall on weekends. However, some do so to boost morale and loyalty. According to the US Bureau of Labor Statistics, as of 2019, about one-third of workers were eligible for 10 to 14 days of PTO after one year of service.
What Does the Average Working Month Look Like?
Whether you’re paid 4-weekly or monthly, you’ll probably want to know how many hours you’re getting paid for. Here’s how that time spent working compares to the rest of the world.
How many work hours in a month today vs 100 years ago?
Assuming a full-time role with a traditional schedule, calculating today’s work hours in a month generally looks like this:
40-hour workweek × 4 weeks = 160 hours per month
But that’s a rough estimate. Not every month has exactly four workweeks, and not everyone follows a 40-hour schedule. Some countries count workdays instead of full weeks. A more accurate way to calculate monthly work hours is:
40 hours/week × 52 weeks/year ÷ 12 months = 173.33 hours/month
Still, if we go with the rough 160-hour estimate, how does it compare to working hours a century ago?
In the early 1900s, amid industrial growth and global upheavals, work hours were significantly longer. In 1919, the average manufacturing workweek was about 50 hours, or roughly 200 hours per month. Over time, labor reforms helped reduce this. As of January 2023, the average workweek is 40.4 hours, translating to about 161.6 work hours per month.
How many hours in a month are there overall?
Thirty days has September, April, June, and November, all the rest have thirty-one, except for February. You may remember this rhyme from your schooldays, but it is still helpful when figuring out how many days and hours there are in a month.
So, let’s calculate:

Working 9 to 5? Here’s What the Average Working Week Looks Like Today
How many work hours are there in a week?
In 2024, full-time employees worked 42.9 hours per week (in the US).

How much time do we spend working on average?
Ever wondered just how much of your week you spend working? Let us break it down for you with some handy math.
7 days in a week x 24 hours in a day = 168 hours in a week
So, if we take the average working week of 40 hours per week and make it a percentage we get:
23.8% of our week spent working

What is the average workweek in North America, Europe, and Asia?
We might have the impression that some nations are more laid-back than others, but is it really the case? Here are the true stats on the average working week in North America, Europe, and Asia. As you can see, the average work week hours in the US, for example, is under 40 hours.

What are working hours in North America, Europe, and Asia?
We know the average working week across the world can range from 29 hours to well over 40 hours per week. But when do people work? Across the world, business days vary.
In the USA and much of Western Europe, the average working week is 9 am to 5 pm from Monday to Friday. Meanwhile, in Japan, the average business day runs from 8.30 am to 7 pm from Monday to Friday. However, in Saudi Arabia, the workweek starts on Sunday at 8 am. They work till noon, then take a 3-hour break before returning to work from 3 pm till 6 pm. Let’s take a look at some other daily routines around the world.

Working Laws — How Many Hours Can a Young Person Work?
From getting their first paper round to that first “proper” job, it’s vital young workers receive the support and protection they need. Here are the rules employers need to know today.
How many hours can a minor work? Today vs 100 years ago
In the UK, child labor laws began with the Factory and Workshops Act, which banned children under 10 from working in factories or workshops. That was all the way back in 1878.
Before then, it was legal for kids, even under 10, to work in industrial settings. Just two years later, in 1880, the Education Act made school attendance compulsory. So, what was happening across the Atlantic?
In the United States, the turning point came in 1938 with the Fair Labor Standards Act (FLSA). This law outlawed exploitative child labor and introduced strict rules for the employment of minors. But what did life look like before that?
A century ago, child labor was widespread. Kids as young as 10 — and sometimes as young as 5 — were expected to work. Not just helping around the house, but doing full labor in roles like:
- cotton picking and mill work
- factory jobs
- chimney sweeping
- retail work
- selling newspapers
- farming and more
Hard to imagine today, but this was once the norm. So, what changed? Society’s mindset.
Between 1908 and 1924, photographer Lewis Hine documented child labor across the U.S. for the National Child Labor Committee (NCLC). His photos exposed the harsh realities kids faced on the job.
Gradually, public opinion shifted. Wealthier families began to believe that children should be supported by parents, not be the providers.
By 1938, the FLSA became law, setting child labor limits that remain the foundation of youth employment regulation in the U.S. today.
What does the FLSA say exactly?
FLSA prohibits oppressive child labor and sets the following rules for non-exempt children, minimum age of:
- 18 years for hazardous occupations
- 16 years for employment in non-hazardous conditions
- 14 years for selected occupations – includes restrictions on hours and work conditions
Caught using oppressive child labor? The fine is $11,000 for every violation with up to $50,000 fine for death or serious injury of a minor. And this can be doubled for repeat offenders.
Think child labor is a thing of the past? It’s not! Since 2007, over 9,700 employers have been found guilty of violating these regulations – and that’s just the ones that were caught.

How Many Hours Can a Part-Time Employee Work Without Benefits?

Eligibility for employment benefits, such as paid time off, stock options, health insurance, and more may depend on how your staff is classified.
- Full-time employees are eligible for benefits
- Part-time employees are not always eligible for benefits
- Full-time is generally considered 40+ hours a week work
- Part-time employment is usually less than 30 hours a week
BUT! It’s not that simple. Calculating whether you have a full-time or part-time worker should be done using data given by the Bureau of Labor Statistics.
Should your employee receive benefits? If they are full-time – YES! If they are part-time, check your local laws. For example, in Hawaii, employees that work more than 20 hours per week are eligible.
In short, according to the Affordable Care Act, in 95% of cases, if your employee works more than 30 hours per week, they will be entitled to benefits.
How Many Hours Can You Work a Day in North America, Europe, and Asia? Maximum Working Hours per Day
