How Many Working Days Are in a Year? (2025, 2026, 2027 Breakdown)

The Quick Answer

For the United States, the numbers are:

The US has 11 federal holidays, but when a holiday falls on a weekend, the observed day shifts to a weekday. The actual count of weekday holidays varies slightly year to year, but 251 is the standard for most recent years.

A quick note on why that number sometimes shows as 250 or 252 in other sources: it depends on whether you count "observed" holidays that shift to a weekday, and whether a given year has holidays landing on weekends. In 2026, Independence Day (July 4) falls on a Saturday, and the observed day (Friday, July 3) is what actually affects the working day count. Some counters miss this substitution.

The Formula

It's straightforward:

Working days = Total days - Weekend days - Public holidays (on weekdays)

A non-leap year has 365 days. That's 52 weeks (364 days) plus 1 extra day. The number of weekend days is typically 104 (52 Saturdays + 52 Sundays), but can be 105 if the extra day falls on a Saturday or Sunday.

Leap years add one more day. If it lands on a weekday, you get 252 working days instead of 251 (assuming the same number of holidays).

Where it gets tricky: company-specific holidays, half-days (like Christmas Eve, which many US companies give as a half day), and "floating holidays" that employees can assign to any date. If you're doing precise project planning, you really need three numbers: statutory holidays, company holidays, and expected PTO. The statutory number is the baseline, but it's almost never the whole story.

Working Days by Country

This is where it gets interesting. The differences are bigger than most people realize.

Japan has 16 national holidays but also the cultural expectation of using fewer vacation days than allocated. India's count is all over the place because each state sets its own list. Germany varies by Bundesland — Bavaria gets the most holidays, and Berliners get the fewest.

What this table doesn't capture is statutory vacation days, which dramatically change the picture. The UK mandates 28 days of paid leave (including bank holidays). Germany mandates 20 days minimum vacation plus the 9–13 holidays. France mandates 25 vacation days plus the 11 holidays. The US mandates exactly zero days of paid vacation at the federal level — it's entirely up to the employer. So while the US has more "working days" on paper, a German employee with 30 days vacation (common for experienced workers) and 13 Bavarian holidays actually works fewer total days than an American with 10 days PTO.

Working Days by Quarter

Annual totals are useful, but most planning happens at the quarterly level. Here's how 2026 breaks down for the US:

Q4 is always the shortest in the US because of the Thanksgiving-to-Christmas holiday cluster. I've worked with project managers who didn't account for this and consistently underdelivered on Q4 commitments. If you're estimating a "3-month project" starting in October, you've actually got about 61 working days, not 65. That's almost a full week less than Q2.

The Weekend Problem: Not Everyone Gets Saturday-Sunday Off

Everything above assumes a Monday-to-Friday workweek. But about 40% of the world's workforce doesn't follow that pattern. Israel's standard workweek is Sunday through Thursday. The UAE switched from Sunday-Thursday to Monday-Friday in 2022, but Saudi Arabia still uses Sunday-Thursday. Many Middle Eastern countries have Friday-Saturday weekends. Bangladesh uses Friday-Saturday. Nepal uses Saturday as the only weekly day off (a 6-day workweek).

This matters for global teams. If your Tel Aviv office works Sunday through Thursday and your London office works Monday through Friday, you have exactly four overlapping workdays per week. Schedule a Friday deployment? Your Israeli team is off. Schedule a Sunday standup? Same problem. I've managed distributed teams across these splits, and the only workable solution is to treat the overlap days as sacred — no one takes meetings outside the 4-day intersection unless absolutely necessary.

Why This Matters for Planning

I use working-day counts constantly in project estimation. If a client says "deliver in Q2," I need to know that's roughly 64 working days in the US but could be 58 in Germany depending on the state. Sprint planning across international teams falls apart if you assume everyone has the same calendar.

For payroll, the number matters for calculating daily rates. A salaried employee earning $120,000/year in the US effectively makes about $478/day ($120,000 ÷ 251). Getting the divisor wrong by even a few days compounds into real money over a year.

Contractors and freelancers feel this even more acutely. If you bill by the day at $800/day and you're estimating annual revenue, the difference between 251 and 245 working days is $4,800. Factor in realistic PTO (say 15 days), sick days (5), and admin days (10), and your actual billable capacity might be closer to 220 days. The people I know who freelance successfully all track this number obsessively — it's the difference between a sustainable business and chronic underearning.

For software specifically, working-day calculations show up in SLA agreements ("5 business days response time"), financial settlement windows ("T+2 business days"), and shipping estimates. Amazon's "arrives by" dates factor in business days, warehouse holidays, and carrier-specific non-delivery days. Getting it wrong means either overpromising (bad for customers) or underpromising (bad for conversion rates).

Tools for Counting Working Days

If you need to calculate business days programmatically, here's the landscape by language:

In Excel, NETWORKDAYS(start, end, holidays) does exactly what you'd expect. Pass a range of holiday dates and it returns the count of working days. There's also NETWORKDAYS.INTL, which lets you define custom weekend days — useful if your workweek is Sunday–Thursday.

In Python, numpy.busday_count() is fast and supports custom holiday arrays. If you don't want a numpy dependency, a simple loop checking weekday() < 5 works for small ranges. The pandas.bdate_range() function generates a range of business dates if you need the actual dates rather than just the count.

In JavaScript, there's no built-in function — you'll need to loop through dates and check the day of week. Libraries like date-fns provide eachWeekdayOfInterval() for this. Our business days calculator handles holidays for multiple countries automatically.

In SQL, it depends on your database. PostgreSQL has no built-in function, but a common approach generates a date series and filters out weekends and holidays. MySQL's approach is similar. Oracle has NUMTODSINTERVAL and business calendar extensions in Oracle Applications, but vanilla SQL requires manual calculation everywhere.

Frequently Asked Questions

How many working days are in 2026?

In the United States, 2026 has 251 working days (365 days minus 104 weekend days minus 10 weekday federal holidays).

Is the number of working days the same across countries?

No. It varies significantly. Japan has only about 245 working days due to 16 national holidays. India can have as few as 230 depending on the state. The UK has about 253 because it has fewer public holidays than most countries.

How do I calculate business days between two dates?

Count the weekdays between the two dates, then subtract any public holidays that fall on weekdays in that range. In Excel, use NETWORKDAYS(). In Python, numpy.busday_count() handles it. Our business days calculator does this automatically.

How many working hours are in a year?

In the US, a standard work year is approximately 2,008 hours (251 working days multiplied by 8 hours per day). This does not account for paid time off, sick days, or company holidays beyond federal ones. The actual hours worked varies by employer and industry.

Does a leap year add an extra working day?

It depends on what day of the week February 29 falls on. If the extra day lands on a weekday (Monday through Friday), the year gains one additional working day. If it falls on a weekend, the working day count stays the same as a non-leap year with similar holiday alignment.

What is the NETWORKDAYS function in Excel?

NETWORKDAYS is an Excel function that calculates the number of working days between two dates, automatically excluding weekends. You can optionally pass a list of holiday dates to exclude those as well. The syntax is NETWORKDAYS(start_date, end_date, [holidays]).

Which country has the fewest working days per year?

Among major economies, Japan has one of the fewest at roughly 245 working days due to 16 national holidays. India can have as few as 230 working days in some states because of extensive regional holiday lists. Cambodia also ranks low with around 28 public holidays annually.
